8. Catalytic Activity of Pyrite for Coal Liquefaction Reaction

Abstract

Catalytic activity of pyrite on coal liquefaction has been investigated with a 5L batch-autoclave. The following conclusions are obtained. (1) Pulverized pyrite exhibits high catalytic activity for asphaltene hydrogenating reaction because pulverization increases its contact rate with reactant and the number of active-site on its outer surface. (2) It is inferred that catalytic activity of pyrite is related to chemical state of Fe and S on its surface.
