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

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.

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

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.

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.
