GTL (Gas to Liquids) and CTL (Coal to Liquids) + HT GCR (High Temperature Gas Cooled Reactors) = Cheap Hydrocarbons w/ Excellent EROEI

Unconventional liquid fuels are slated to provide ever growing proportions of future demand for transportation fuels. The burgeoning success of plants such as Shell's Pearl GTL plant in Qatar herald a new era of liquid fuels production.
In terms of what GTL is, it is the process of chemically turning natural gas into cleaner-burning liquid products, including fuel, base oil for lubricants and feedstock for chemicals. To produce, the process firstly involves methane and oxygen which are converted into a mixture of hydrogen and carbon monoxide known as synthesis gas or syngas. This is then fed to a reactor with a proprietary Shell catalyst that accelerates the conversion of the mixture to long-chained waxy hydrocarbons and water.

From the GTL reactor, the long-chained hydrocarbons are then reacted with hydrogen and ‘cracked,’ into a range of smaller molecules of various sizes using another proprietary Shell catalyst. This process is referred to as ‘hydrocracking.’ The final step is distillation. Various boiling points are reached to separate out the products, which can be in the form of GTL naphtha, GTL kerosene, GTL normal paraffins, GTL gas oil, or GTL base oils. These are then eventually fed to their own storage tanks ready for use.

...One of the products, GTL gasoil (diesel-type fuel), can contribute significantly to the diversification of the diesel fuel supply. This product can reduce local emissions of nitrogen and sulfur oxides and particulate matter. Because it contains virtually no sulfur or aromatic compounds and has a high cetane number – a measure of combustion quality – GTL gasoil burns more efficiently than conventional oil-based diesel and thus produces fewer local emissions and less black smoke than conventional diesel. The high cetane of GTL gasoil can lead to noise reductions in certain engines under certain driving conditions and improve cold start performance. GTL gasoil can also be blended with conventional diesel and/or biodiesel and used in the same vehicles and infrastructure, thus offering a low investment cost compared with other alternatives.

GTL Kerosene is an alternative to conventional oil-based kerosene. Its primary use is expected for aviation. GTL kerosene can be used as a blend with traditional jet fuel without any modifications to existing aircraft and engines. Given that the aviation sector will rely on liquid hydrocarbons for decades, this fuel can help support the future energy needs of the industry, and offer customers fuel diversification. GTL kerosene has higher energy density than conventional oil-based kerosene and this reduces the required fuel payload, thus aircraft may be required to carry less fuel weight to cover the same distance. _QatarShell
When even pro-nuclear activists such as Rod Adams are speaking out in favour of a coal - nuclear partnership to produce liquid transportation fuels, you should understand that people are finally beginning to look at the possibilities.
Coal is a valuable resource that can be safely mined for centuries by well-trained and compensated miners. Instead of eliminating the use of coal, I would prefer to help coal miners and coal mine owners to recognize that they could make more money and sell a cleaner product if they upgraded their fuel at the mine rather than shipping a dirt-filled, unrefined product that sells for a huge discount in the energy market.

...My pitch to the coal industry would be to use cheap, clean nuclear heat to convert H2O and their carbon rich fuel into a refined hydrocarbon that could compete with petroleum products.

...Shipping oil instead of coal from our domestic mines would also be very beneficial to the US national security and to the prosperity of the world. Just think about the positive impact that substantially lower US demand would have on the price of diesel fuel delivered to a developing country. _RodAdams
Until more people are able to think of energy in multi-disciplinary, multi-industrial terms, societies will be forced to pay higher prices for fuels and energy than is necessary. By including cheap and unlimited nuclear reactor process heat into the fuel production mix, we can immediately bring CTL, GTL, bitumens to liquids, kerogens to liquids, and even biomass to liquids (BTL) into the feasible and profitable arena.
Fortunately, more nuclear advocates are beginning to understand the importance of cleanly integrating coal and gas into the overall energy and fuels mix. But we need more bright chemical engineers like Robert Rapier, and physicists like Tom Murphy, to crunch the numbers once again -- this time including the powerful impact of high temperature process heat from modular and mini-modular HT gas-cooled nuclear reactors.
By utilising scalable, factory produced reactors which can be sited at the point of production of gas, coal, bitumens, kerogens, methane hydrates -- and even biomass in some situations of intensive cultivation -- it should be clear to any objective observer that a new era of hydrocarbon production is quite feasible.

Government action could certainly prevent this development. The great carbon hysteria delusion -- if firmly enacted into law in the developed world -- would not only kill unconventional fuels, it would kill the economic viability of the underlying societies themselves. That is what several governments, from the UK to Obama's US to Australia to the EU are attempting to do in various ways.

A far less likely -- but still potentially effective -- way to stop the revolution in unconventional fuels, is for the national oil companies of OPEC and other oil dictatorships to route needed funds into oil field production, exploration, discovery, and development. It would be easy for existing oil fields and fields under development to ramp up production to overwhelm even the current inflated levels of global demand -- if the equipment, manpower, and funding were allotted for the purpose. But this will not be done, because governments from Russia to Venezuela to Saudi Arabia etc need oil prices to remain artificially high so that they can use oil profits to pacify unstable populations and pay off highly placed insiders.

Extra bonus just for loyal Al Fin readers: China apparently has vast shale gas reserves. China is vigorously pursuing the development of these gas reserves.

In the early phases this will help the North American engineers and drilling companies who assist in China's learning curve for shale gas production. It will also help China negotiate more favourable gas prices with Russia's Gazprom.

In the long run, these huge natural gas reserves will help reduce China's oversize demand for imported crude oil. This down-shifting of global oil demand will occur due to China's increasing use of an up and coming coal -- natural gas hybrid liquefaction process. This process of synthetic fuels production should become particularly economical when using cheap nuclear process heat as the primary heat source.

Russia itself will be forced to adopt GTL technologies as it finds some of its best customers turning to their own shale gas reserves, and turning away from Gazprom.

Questioning the Peak Oil Dogma

We are being told once again to expect ever-higher fuel and energy prices in the coming years, with a consequent drag on economies. Underlying these gloomy predictions is an underlying belief that humans are running short on sources of energy -- the peak oil dogma -- and will have to pay more as shortages worsen. But is the peak oil dogma based upon superstition, or fact?
Myth of Scarcity

Unless humans look for energy, they are unlikely to find it. But if they are willing to use their brains and their eyes, they can detect ever more geologic locations where a wide variety of hydrocarbon fuels were formed.
It is said that the cheap and easy oil is all gone, and that the low hanging fruit has been picked. But the "cheap and easy oil" was not that cheap and easy when it was first tapped. Technology had to be developed for each type of deposit to be exploited. This will continue to be the case.
This is an IEA estimate of hydrocarbon resource. It is very likely to be a vast unerestimate, as is typically the case.
Here is another scholarly estimate of world hydrocarbon resources, also likely to have significantly underestimated the true resource.
Here is another estimate, which clearly fails to account for the economic impact of cheap and abundant nuclear process heat from high temperature gas-cooled reactors, in the processing of gas to liquids, coal to liquids, kerogens to liquids, etc.
This graphic includes an estimate of comparison between relative carbon resources of gas hydrates and all other hydrocarbons.
This graphic compares relative gas hydrate resources in various locations.
This graphic looks at recoverable fossil fuel resources by nation. It underestimates a number of probable resources across the board, including shale oil & gas and several others.

When humans are confronted with resource shortages, they take a number of parallel approaches to relieving the resource scarcity.

But when shortages are caused by political or ideological perversity, there may be much less that humans can do, until the political or ideological constrictions are removed. That appears to be the situation associated with the multiple political dogmas of peak oil, carbon hysteria, overpopulation, and various other faux environmental political dogmas.

In the modern world, Russia, China, India, and a number of third world and emerging states stand out as distinct outliers from the global faux environmental rush to energy suicide. It is unlikely that Europe, Oceania, and North America will be willing to take the final faux environmental step of cutting their own throats (figuratively speaking), when such a large part of the world stands ready to loot their corpses in a very un-PC, un-green manner.

A Dynamic View of Continental Movements, and the Birth and Death of Oceans and Seas


500 Million Years of Continental Rearrangement

Oil and gas are generally formed under seabeds, when organic matter is covered with sediment, deprived of oxygen, and exposed to heat and pressure over long time periods. The video above presents one scientific theory of how continents move about, forming new seas and destroying others.

Confined seas that are fed a rich diet of sediments and nutrients are the best oil formers -- in other words, those that are fed by large, seasonably variable rivers. Of course, rivers will necessarily be birthed, change their courses, and die over geologic timespans -- just like seas.

That is why mental prospectors of ancient oil-forming seabeds must visualise the movement of the continents, the mountains, the rivers, the seas, over time.
Supercontinent Formation
In a paper published Feb. 9 in the journal Nature, Yale researchers introduce a process called orthoversion, in which each succeeding supercontinent forms 90 degrees from the geographic center of its ancient predecessor. Under the theory, the present-day Arctic Ocean and Caribbean Sea will vanish as North and South America fuse during a mutual northward migration that leads to a collision with Europe and Asia.

“After those water bodies close, we’re on our way to the next supercontinent,” said Ross N. Mitchell, the Yale doctoral student who is the paper’s first author. “You’d have the Americas meeting Eurasia practically at the North Pole.” _Physorg
Oil & gas are renewable resources -- but on a long timescale. Humans have barely begun to discover all the hydrocarbon resources which they will ultimately be able to economically exploit.

Plan ahead so as to ride out the waves and chop that are certain to come along the way.

Peak Oil: Meet Sophisticated Coal-Biomass to Liquids CBTL

There is more than 250 billion tons of recoverable U.S. coal reserves – equivalent to an estimated 800 billion barrels of oil, compared to Saudi Arabia’s proven reserves of 260 billion barrels

_National Mining Association_via_Accelergy.com
EERC PDF

Accelergy's Coal Biomass to Liquids (CBTL) process utilises direct liquifaction of coal (using hydrogen from gasification of algal biomass and coal), combined with advanced catalytic processing of hydrotreated coal and hydrotreated algal lipids, to produce advanced hydrocarbon liquid fuels at high yields.

Accelergy is developing its coal biomass to liquids technology in several locations across the US, in China, and for the US military.
In the United States, Accelergy is working on demonstration facilities in Pennsylvania, Montana, and North Dakota. Accelergy's process can be tuned to utilize a wide range of feedstocks, and the company is currently exploring the use of both coal and natural gas in the U.S, along with biomass.

The company is also targeting its efforts in China since the country already has a small number of synthetic fuels plants where coal is converted to a liquid, he said. China is also the world's largest producer and consumer of coal. _Energy.AOL.com

Consider these facts about CBTL [Coal Biomass to Liquids]:

Abundant Supply: There is more than 250 billion tons of recoverable U.S. coal reserves – equivalent to an estimated 800 billion barrels of oil, compared to Saudi Arabia’s proven reserves of 260 billion barrels. (Source: National Mining Association)

Environmental Benefits: Combining the Coal-to-Liquids (CTL) and Biomass-to-Liquids (BTL) processes, Accelergy removes 20% of the CO₂ emissions associated with standard refining methods, resulting in cleaner fuels that reduce nitrogen oxide and particulate emissions and enabling use of higher efficiency engines.

Reliable Sources: Coal currently provides more than half of the nation’s electricity and is the largest single source of overall domestic energy production at more than 31% of the total, according to the National Mining Association. Additionally, our feedstocks can be grown domestically an land deemed unsuitable for food crop cultivation. _Accelergy

More on direct coal liquefaction:
• Direct liquefaction processes add hydrogen to the hydrogen deficient organic structure of the coal, breaking it down only as far as is necessary to produce distillable liquids.
• Coal dissolution is accomplished under high temperature (~400 0 C) and pressure (~1500-3000 psi) with hydrogen and a coal-derived solvent.
• The coal fragments are further hydrocracked to produce a synthetic crude oil.
• This synthetic crude must then undergo refinery upgrading and hydrotreating to produce acceptable transportation fuels. _Direct Liquefaction of Coal PDF

More on Accelergy's potentially lucrative move into the Chinese market

Accelergy's approach to CBTL is rather sophisticated, involving some advanced Exxon Mobil technology along with other imaginative innovations. The fact that Accelergy is working with the US military, with civilian US entities, and inside China, indicates that the company is following an aggressive path of expansion and development.

Taken from a previous posting at Al Fin Energy

With its vast resources of coal, natural gas, bitumens, kerogens, oil, uranium, thorium, and more, North America is well situated to transition from the fossil fuel age to the advanced fission / fusion age.

Bad government is a far greater threat to North America and Europe than resource depletion, climate catastrophe, or overpopulation doom. Fear only bad government and the accompanying twin demons of debt and demographic decline.

Peak Oil: Meet Primus' Competitive Biomass to Gasoline $1.95/Gal

Get Adobe Flash player
More information on Primus
GCC article about Primus' plans
Primus’s process is based on a proprietary variant of the ExxonMobil Methanol-to-Gasoline process, simplified to produce standard gasoline without need for separation or further treatment, the company says. The Primus process consists of three main steps:
  1. Gasification of biomass (feedstock flexible) to produce a syngas;
  2. CO2 separation and scrubbing of the syngas;
  3. catalytic liquid fuel synthesis using a four-stage catalytic system (the MTG variant).
Primus says that its gasoline is cost-competitive with fossil fuels without subsidies, utilizing carbon-efficient and high fuel-yielding non-agricultural biomass that does not compete with foodstocks.

A February 2011 report from the US Department of Energy’s National Renewable Energy Laboratory (NREL) conclude that gasoline produced via the methanol-to-gasoline (MTG) route (earlier post) using syngas from a 2,000 dry metric tonne/day (2,205 US ton/day) biomass-fed facility could have a plant gate price (PGP) of $1.95/gallon US ($0.52/liter). _GCC

The biomass is pelletised, then gasified. The syngas is converted to methanol, and the methanol is converted directly to gasoline, via Exxon Mobil's highly efficient MTG process -- as modified by Primus. More on MTG:
In the MTG process, dimethylether (DME), the dehydrated derivative of methanol, is reacted over a ZSM-5 zeolite catalyst, on which the chain growth of molecules is sterically hindered, thus allowing only production of gasoline and lighter material. The gasoline product from the MTG process has more than 51 compounds, similar to straight-run gasoline in a petroleum refinery.

This mixture is then separated using a process similar to that used in a gasoline refinery. The design utilized in the NREL model utilizes five distillation columns to separate the remaining gas, LPG, light gasoline, and heavy gasoline. The remaining gas is sent to the fuel combustor. The light gasoline continues without further treatment. The heavy gasoline could proceed through a durene isomerizer in order to eliminate the presence of the 1,2,4,5-tetramethylbenzenes by converting them to 1,2,3,5-tetramethylbenzenes. This stream would then be merged with the light gasoline. The two product streams are LPG and gasoline. _GCC

This is an entirely renewable biomass to gasoline process which is likely to impact the fossil fuels markets in good time. Perhaps the main obstacle to a large scale adoption of biomass to liquid fuels, is the current very cheap price of natural gas.

A Pandemic of Malthusian Illiteracy

Global economy optimists however say that "Malthusian illiteracy" lurks behind remaining adherents of Peak Oil theory - which basically says conventional oil production will stagnate and fall but demand will go on growing. _MarketOracle
As knowledgeable analysts come to understand that oil demand, rather than oil supply, is currently in the driver's seat, some of the impetus behind the peak oil panic has subsided. And yet the "Malthusian Impulse" continues to drive many observers, against their more rational proclivities. Still, global hydrocarban reserves continue to grow, year after year, and oil demand is slated to decrease in time.

New sources for transport fuels are likely to come from many directions, including new gas-to-liquids (GTL) technologies. Oxford Catalyst's microchannel GTL technology is very much in demand, as are other new varieties of GTL technologies. The market for GTL fuels may be more than 20 million barrels per day! Imagine the impact of that huge new supply on the global oil market. (Note that approximately between 5 and 10 million barrels per day could be produced via GTL from currently flared gas alone. Stranded gas could double that number.) More information at this PDF white paper download from Velocys, creator of the Oxford Catalysts microchannel technology.

A more conventional source for GTL transport fuels is the large scale technology championed by Shell.
In 2011, Shell began shipments from its Pearl GTL project in Qatar...The project is able to produce 140,000 b/d of fuel and 120,000 b/d of ethane and condensates... _Petroleum Economist

And that is just the beginning. As long as the huge price spread between the cost of natural gas and the cost of crude oil remains, more and more GTL projects will kick in to take advantage of this "easy money."

Second and third generation biofuels from biomass technologies are beginning to come on line, slowly (consult Al Fin Energy blog for updated news on this topic). Advanced biofuels technologies are not likely to take an appreciable bite out of crude oil demand for another 5 or 10 years. As long as natural gas prices stay this low, only the most efficient biofuels projects will be able to compete in the liquid fuels markets without government subsidies. But by the year 2030 if the technology continues to develop, the writing will be on the wall. This is a biological world, after all.

Advanced nuclear power technologies are likely to aid the development of new fuels technologies of all kinds, supplying safe and abundant power and heat for a multitude of energy development projects from oil sands to oil shales to biomass and aquaculture projects in cold climates, irrigation and desalination of saltwater in arid climates etc etc.

Other factors leading to a decreased demand for crude oil includes the increasing use of both natural gas and biomass as feedstock for the vast chemicals industry -- an industrial sector previously dependent upon petroleum for feedstock. (see Al Fin Energy blog for much more)

The ongoing global economic downturn and demand destruction extends from Europe to Japan to the US, and is beginning to put stress on the Chinese and Indian economies -- despite all the rah! rah! hype about the coming age of the Chindian global economy. Many nations which have maintained hefty consumer subsidies for transport fuels are being forced to reduce the subisidies. More downward pressure on demand.

Malthusian theories are appealing for their simplicity. And yet the never-ending and never-fulfilled Malthusian predictions of doom ignore the most salient and disruptive human technology of all -- the goal-oriented innovativeness of the human mind.

Despite the best efforts of energy-starvationists in the Obama administration, in the EU bureaucracy, in national bureaucracies of EU nations and advanced nations around the globe -- the prospects for abundant energy and fuels in the future are quite good, as long as the clowns in power do not destroy the economies they oversee.

If you have abundant clean energy and fuels, everything else is doable.
