This process is often known as "Coal to X" or "Carbon to X", where X can be many different hydrocarbonbased products. However, the most common process chain is "Coal to Liquid Fuels" (CTL) Coal liquefaction is the process of converting solid coal into liquid fuel. This process has been developed as a means to utilize coal resources that are ...
obtained from gasification of coal to hydrocarbon liquids. Because the coal is first gasified before conversion to liquid fuels, the FischerTropsch (FT) process for CTL is known as a type of indirect coal liquefaction (ICL). ICL is a completely different approach from DCL for providing liquid fuels from coal. ICL processes first convert ...

Coal and biomass are the main components of hydrocarbon solid fuels. In recent years, bioenergy is the fourth largest primary energy source which is preceded by oil, coal, and natural gas [ 3 ]. By 2019, the world consumption of bioenergy increased by % over the previous year, reaching 2566 Mb/d [ 4 ].
(509) . PNNL develops advanced materials, catalysts, transformational processes, and integrated systems to capture or separate greenhouse gas emissions in a costeffective manner and to efficiently convert fossil hydrocarbons to electricity, fuels, or chemicals.
Fuels may be solid, liquid or gaseous. They may be natural or artificially prepared. Classification # 1. Solid Fuels: i. Wood: Except in industries in which a large amount of waste wood is available, this material is not generally considered as a commercial fuel. The heat value of wood varies both with kind of wood and with the water content.

In the process of our subject, "United States Patent 8,999,134 Manufacturing CarbonBased Combustibles by Electrochemical Decomposition of CO2", it is seen that Carbon Dioxide, in combination with Water, H2O, can be efficiently converted into an hydrocarbon synthesis gas mixture of Carbon Monoxide and Hydrogen from which, using known and ...
ICL includes two steps; in the first step, coal is converted into syngas ( Coal+H2OCO+H2), and during the last step, syngas is synthesized in the presence of a catalyst into liquid fuels. Syngas can be converted into liquid hydrocarbon through the FischerTropsch process or by converting syngas into oxygenates such as methanol, dimethyl ether ...
Direct liquefaction of coal can be achieved with and without catalysts (represented by R), using high pressures (200 to 700 atmospheres) and temperatures ranging between 425 and 480 °C (800 and 900 °F). In the indirect liquefaction process, coal is first gasified to produce synthesis gas and then converted to liquid fuels
