Abstract

Unsupported CoMo oxides of various compositions were investigated by IR, XRD and XPS techniques. They contain CoMoO4 plus the corresponding oxide with slight Mo enrichment on the surface. After reduction with H2, the changes in their catalytic activity in thiophene HDS were monitored with the reactant itself as the sulfiding agent. Relatively high activities with good C4-selectivities were observed when the degree of sulfidation of the catalysts was relatively low. Partially sulfided surface species possess the highest activity, especially in hydrogenation.
