Comparison of bulk CoMo bimetallic carbide, oxide, nitride and sulfide catalysts for pyridine hydrodenitrogenation

A comparison between Co4Mo6 catalysts in carbide, nitride, sulfide, and oxide forms was studied for HDN of pyridine. The activities of these catalysts at steady state are shown in the order of: CoMoCx > CoMoNx > CoMoSx > CoMoOx.
