ABSTRACT:
A desulfurization process is described which consists of heating an organic hydrocarbon like coal or bitumen in a stream of a gaseous or liquid trapping material for hydrogen sulfide (H.sub.2 S). The organic sulfur in the hydrocarbon decomposes and releases H.sub.2 S which reacts with the trapping material to form a metastable sulfur compound. The resulting gaseous or liquid stream is recovered and decomposed in a subsequent step to form H.sub.2 S and to the original trapping material. The trapping material is recovered and recirculated into the reactor. Ethylene, propylene and other olefins, as well as aldehydes and ketones are found to be excellent trapping materials.
