Gasification
WHAT IS GASIFICATION?
Gasification is mainly a high-temperature partial oxidation process for converting carbonaceous materials into a synthesis gas composed mainly of carbon monoxide and hydrogen. A number of chemical reactions are involved, some exothermic and some endothermic:
During the gasification process, the sulphur present in the feedstock reacts to produce mainly hydrogen sulphide (H2S) and carbonyl sulphide (COS):
Sulphur can therefore be readily recovered in its elemental form or as sulphuric acid, both marketable commodities.
