We have, of course, presented many reports here concerning South Africa's Coal conversion industry, wherein South Africa Synthetic Oil Limited, "SASOL", has been converting Coal at multiple factories into synthetic petroleum fuels for well more than half a century.
Sasol utilizes a modern version of the nearly-ancient Fischer-Tropsch process for converting Coal into liquid hydrocarbons, a technique known generically as "indirect" Coal conversion, since Coal is first partially combusted to form a "synthesis gas", or "syngas" blend of Carbon Monoxide and Hydrogen. The syngas is then catalytically, chemically condensed into hydrocarbons.
