International Classification:

B01J 27/22
B01J 27/24

US Classification:

502177, 502180, 502182, 502183, 502184, 502185

Abstract:

The present invention provides methods of synthesizing molybdenum disulfide (MoS) and carbon-containing molybdenum disulfide (MoSC) 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.

Abstract:

Embodiments of the invention are directed to CoMoS2 catlaysts, methods of making and using, as well as electrodes and systems incorporating such. Synthesis of CoMoS2 catalysts using ATM treated with different amines and ammonium bromide salts including 1-dodecylamine, diethylenetriamine, tetradecyltrimethylammonium bromide and cetyltrimethylammonium bromide, to form different alky containing ATM precursors. These materials are amorphous with porous surfaces that show reasonably big surfaces area due to the number of exposed edge sites, and increased catalytic activity as electrocatalysts for hydrogen generation.
