P-7.石炭の接触水素化液化における水の促進効果 : モデル化合物の接触水素化(Poster Session)

Model compound reactions of 4-(1-naphtylmethyl) bibenzyl (NMBB) were carried out at 350-425℃ under H_2 pressure in order to examine the activity of MoS_2 catalysts generated from ammonium tetrathiomolybdate (ATTM) with and without added water for C-C bond cleavage and hydrogenation of aromatic ring. The MoS_2 catalysts generated from ATTM with added water were much more effective for C-C bond cleavage and hydrogenation of aromatic rings at 350-425℃ than those from ATTM alone. The MoS_2 catalysts have larger surface area and less crystalline than those from ATTM alone. The larger surface area and higher porosity of the MoS_2 catalysts from ATTM should be responsible, at least in part, for the high activity observed in the catalytic reactions when compared to the catalysts from ATTM alone.
