Patent No. 7,223,713

This patent produces a MoS2 catalyst from ammonium and amine thiomolybdate under high temperature and pressure inside a batch reactor. This method also allows for doping the catalyst with a metal.

The present invention provides methods of synthesizing molybdenum disulfide (MoS2) and carbon-containing molybdenum disulfide (MoS2-xCx) catalysts that exhibit improved catalytic activity for hydrotreating reactions involving hydrodesulfurization, hydrodenitrogenation, and hydrogenation. The present invention also concerns the resulting catalysts. Furthermore, the invention concerns the promotion of these catalysts with Co, Ni, Fe, and/or Ru sulfides to create catalysts with greater activity, for hydrotreating reactions, than conventional catalysts such as cobalt molybdate on alumina support.
