FischerTropsch (FT) synthesis is a heterogeneous catalytic process that converts biomassderived syngas (mixture of CO and H 2) to synthetic liquid fuels and valuable chemicals. FT synthesis has received renewed interest in recent years due to the necessity to decrease global dependency on fossil fuels. FT synthesis is a promising technology ...

IGCC process which is, no doubt, a complicated energy conversion process formed by many interconnected subsystem modules. In the IGCC process, the coal slurry and oxygen react in the gasifier and generate syngas primarily made of H 2 and CO. The WGS raises the H 2 and CO 2 concentration while reducing the CO content.

The feedstock for the plants is subbituminous coal supplied by Mining, a sister company of Synfuels. Natural gas is also used as a supplemental feedstock. A proprietary ironbased FT process is used to convert the synthesis gas (syngas) produced by the gasifiers to gasoline, light olefins (alkenes), and a variety of other products.

Coal utilization Gasification: While the goal of combustion is to produce the maximum amount of heat possible by oxidizing all the combustible material, the goal of gasification is to convert most of the combustible solids into combustible gases such as carbon monoxide, hydrogen, and methane. During gasification, coal initially undergoes devolatilization, and the residual char undergoes some ...

Indirect coal liquefaction (ICL) processes mainly include two important steps. In the first step, the coal is gasified and converted into hydrogen and carbon monoxide, also called as syngas. In the second step, the syngas is further synthesized into liquid fuel. Coal is the most abundant energy reserve in the world.
