Pyrite catalysis of coal liquefaction, hydrogenation, and intermolecular hydrogen transfer reactions

Abstract

This work explores the effect of pyrite as a mineral catalyst on several types of reactions occurring in coal liquefaction. Both coal and model compound experiments were carried out. The effect of pyrite on the conversion of coal to preasphaltenes, asphaltenes, oils and gases was determined. Model compound experiments were used to investigate the role of pyrite in catalysing direct hydrogenation with molecular hydrogen. Pyrite was found to exert an influence on all of the reaction processes.
