option is to convert coal into high quality, clean burning transportation fuel. There are two commercially demonstrated routes for converting coal to transportation fuels through gasification (Figure 1). The widely known FischerTropsch process was first discovered in the 1920s. It has been commercially practiced by Sasol in several

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 ...

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 ...

Today Sasol produces the equivalent of 150,000 bbl/day of fuels and chemical feedstock from more than 40 million tons of low grade coal. In converting coal to petroleum products, coal is first gasified with oxygen and steam to syngas, a mixture of H{sub 2} and CO, which after purification is converted to hydrocarbons and some oxygenates by ...

Figure 1 shows a diagram depicting an estimate of global flows of fossil fuel feedstocks to chemicals production in 2013. Coal figures prominently in the flows to ammonia and methanol, which in turn feed into a wide range of plastics and chemicals; most of the coal use involves gasification to syngas on these conversion routes.

The influence of coal slurry concentration and oxygen/coal ratio on the syngas contents is studied as CO, CO 2 and H 2 contents can reveal the syngas quality. To enhance the gasification process and generate raw syngas with high quality, higher slurry concentration and oxygen supply is shown to be one of the suitable solutions.
