Abstract

Nonisothermal hydrodesulphurization of model organic sulphur compounds was carried out in a coal-like environment. The model sulphur compounds represented different types of carbon-sulphur bonds commonly encountered in coal. Similar experiments were also carried out in the presence of troilite (FeS) to investigate the possibility of sulphur migration from the organic compound to the iron sulphide. Results show that sulphur from organic compounds can be absorbed by troilite. Based on this observation it is suggested that during hydrodesulphurization it is possible to have migration of sulphur from the organic to the inorganic phase.
