Abstract

A process is disclosed for the hydrodesulfurization of sulfur-containing hydrocarbon fuel with reduced ternary molybdenum sulfides, known as Chevrel phase compounds. Chevrel phase compounds of the general composition M.sub.x Mo.sub.6 S.sub.8, with M being Ho, Pb, Sn, Ag, In, Cu, Fe, Ni, or Co, were found to have hydrodesulfurization activities comparable to model unpromoted and cobalt-promoted MoS.sub.2 catalysts. The most active catalysts were the "large" cation compounds (Ho, Pb, Sn), and the least active catalysts were the "small" cation compounds (Cu, Fe, Ni, Co.).

Hydrodesulfurization catalysis by Chevrel phase compounds

Technical Report McCarty, K F

The catalytic activity of Chevrel phase compounds (M/sub x/Mo/sub 6/S/sub 8/) for thiophene hydrodesulfurization at 400/sup 0/C has been found to be comparable to or greater than that of model industrial catalysts (unpromoted and cobalt-promoted MoS/sub 2/). The most active Chevrel phase catalysts were those containing the ''large'' ternary component cations Ho, Pb, Sn; the ''intermediate'' cation materials (M = Ag and In) were less active; the ''small'' cation materials (M = Cu, Fe, Ni, and Co) were the least active catalysts. The 1-butene hydrogenation activities of the Chevrel phase catalysts at 400/sup 0/C were much lower than MoS/sub 2/,more »« less

Synthesis and characterization of lead Chevrel phase thin films for hydrodesulfurization catalysis

Journal Article Schewe-Miller, I M; Koo, K F; Columbia, M; ... - Chemistry of Materials

Reactive sputtering has been used to prepare the lead Chevrel phase PbMo{sub 6}S{sub 8} on several substrates. The effect of processing parameters such as H{sub 2}S flow rate, Pb sputtering current, substrate temperature, and annealing temperature were found to be very important in determining sample purity. Formation of PbMo{sub 6}S{sub 8} from an as-deposited material apparently occurred at significantly lower annealing temperatures (400-800{degrees}C), compared to conventional solid-state preparations (1000{degrees}C). The thin films of PbMo{sub 6}S{sub 8} were active thiophene hydrodesulfurization catalysts: the absence of impurities including MoS{sub 2} could be confirmed for these materials, before and after reaction.
