Ethylene addition to CO hydrogenation over sulfided NI, Rh, and Ru

The effect of H{sub 2}S on ethylene addition to CO hydrogenation has been studied over Ni/SiO{sub 2}, Rh/SiO{sub 2}, and Ru/SiO{sub 2} catalysts at 300{degree}C and 10 atm. The major products of the ethylene addition on the unsulfided catalysts are ethane and propionaldehyde which result from ethyle...

Description
Summary:The effect of H{sub 2}S on ethylene addition to CO hydrogenation has been studied over Ni/SiO{sub 2}, Rh/SiO{sub 2}, and Ru/SiO{sub 2} catalysts at 300{degree}C and 10 atm. The major products of the ethylene addition on the unsulfided catalysts are ethane and propionaldehyde which result from ethylene hydrogenation and the insertion of CO into adsorbed ethylene species, respectively. Sulfidation of the catalysts led to the suppression of ethylene hydrogenation and CO hydrogenation. CO insertion over Ni/SiO{sub 2} and Rh/SiO{sub 2} catalysts was insensitive to sulfidation, whereas CO insertion on Ru/SiO{sub 2} was inhibited by sulfidation. Infrared studies of CO adsorption reveal that sulfidation of the catalysts led to the disruption of neighboring surface atoms for bridge CO resulting in the formation of isolated atom sites which may be responsible for CO insertion on the sulfided Ni and Rh catalysts.
