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 ...

Synthetic fuel Wikipedia

Synthetic fuel or synfuel is a liquid fuel, or sometimes gaseous fuel, obtained from syngas, a mixture of carbon monoxide and hydrogen, in which the syngas was derived from gasification of solid feedstocks such as coal or biomass or by reforming of natural gas . Common ways for refining synthetic fuels include the FischerTropsch conversion ...
