The FischerTropsch process is a catalytic chemical reaction in which carbon monoxide (CO) and hydrogen (H 2) in the syngas are converted into hydrocarbons of various molecular weights according to the following equation: (2n+1) H 2 + n CO → C n H (2n+2) + n H 2 O. Where n is an integer. Thus, for n=1, the reaction represents the formation of ...

Coal can also be liquefied directly, without going through the production of synthesis gas. This process is termed coaltoliquid (CTL) and is a reasonably mature technology. The process typically uses the technique of heating under pressure (up to 470°C, 200 bar) and hydrogenation where hydrogen is added to a coalwater slurry. The slurry ...

In industrial chemistry, coal gasification is the process of producing syngas—a mixture consisting primarily of carbon monoxide (CO), hydrogen (H 2), carbon dioxide (CO 2), methane (CH 4), and water vapour (H 2 O)—from coal and water, air and/or oxygen.. Historically, coal was gasified to produce coal gas, also known as "town gas".Coal gas is combustible and was used for heating and ...

Indirect liquefaction processes require first gasifying the solid feedstocks into a syngas. Therefore, while direct coal liquefaction (DCL) takes coal directly into a liquid phase, indirect coal liquefaction (ICL) consists of two major steps: (a) gasification to produce a synthesis gas (syngas); and (b) conversion of the carbon monoxide (CO) and hydrogen (H 2) in the syngas to a range of ...
