In fact, the dominant application of synthesis gas from coal is the production of synthetic hydrocarbons for transportation fuels Fischer Tropsch (FT) synthesis. This is what is primarily done in South Africa by the company and was also one of the methods used by the Germans in WWII to generate liquid fuels; in fact, direct ...

I, built and started in 1955, operated 17 Lurgi FBDB TM gasifiers to convert the syngas produced from subbituminous coal into a wide variety of liquid chemicals. In 2004, this facility retired the gasifiers in favor of natural gas autothermal reformers ( Mills, 2016; NETL, a ).

Such systems allow greaterthanequilibrium conversion of syngas to separate streams of CO 2 and H 2 in a single process step. This has the potential to replace the high and lowtemperature watergas shift process, and the solvent extraction and regeneration processes, with a single reactor unit offering a considerable decrease in both capital ...

Abstract. To produce liquid fuels from coal, either direct or indirect liquefaction routes can be used. The discussion of the former route is the subject of Chapter 6; the latter route will be discussed here. The indirect liquefaction route consists of the conversion of coal to synthesis gas (hydrogen plus carbon monoxide), and then the ...

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 ...

The Slurry Phase DistillateTM Process ( SPD™ process) is at the core of 's GTL technology. The three stage process combines three leading proprietary technologies. In the first Reforming stage, natural gas is combined with oxygen to form a syngas which is then subjected to conversion in the Low Temperature Fischer TropschTM ( LTFT™) Process for the production ...

Production of liquid transportation fuels from coal biomass requires significant amounts of water, for three major purposes: 1) process cooling demands in coal conversion will often be met by wet evaporative cooling, which is associated with consumption of water through evaporation just as ...

The initial syngas can be derived from coal alone or from a coal/biomass mixture. The process is the same when biomass is included, but the amount of CO 2 emitted during the process decreases as the proportion of biomass increases. In the lesscommon Mobil process, the syngas can be converted to methanol, which is subsequently converted to ...
