Sonochemical preparation of supported hydrodesulfurization catalysts.
Sonochemical preparation of Co and Ni promoted MoS(2) supported on alumina was achieved by high-intensity ultrasonic irradiation of isodurene solutions containing molybdenum carbonyl, dicobalt octacarbonyl, elemental sulfur, and Al(2)O(3) or Ni-Al(2)O(3) under Ar flow. The sonochemically prepared catalysts were characterized by elemental analysis, XPS, SEM, TEM, and XEDS, and hydrodesulfurizati...
متن کاملGraphene-supported hemin as a highly active biomimetic oxidation catalyst.
Well supported: stable hemin-graphene conjugates formed by immobilization of monomeric hemin on graphene, showed excellent catalytic activity, more than 10 times better than that of the recently developed hemin-hydrogel system and 100 times better than that of unsupported hemin. The catalysts also showed excellent binding affinities and catalytic efficiencies approaching that of natural enzymes.
متن کاملThiophene hydrodesulfurization catalysis on supported Ru clusters: Mechanism and site requirements for hydrogenation and desulfurization pathways
Kinetic and isotopic methods were used to probe elementary steps and site requirements for thiophene hydrogenation and desulfurization on Ru metal clusters. Turnover rates for these reactions were unaffected by whether samples were treated in H2 or H2S to form metal and sulfide clusters, respectively, before reaction. These data, taken together with the rate and extent of sulfur removal from us...
متن کاملCopolymerization of ethylene with α-olefins over highly active supported Ziegler-Natta catalyst with vanadium active component
The new highly active supported vanadium-magnesium catalyst (VMC) has been studied in α-olefin (1-butene, 1-hexene)/ ethylene copolymerization in the presence of hydrogen. Data on the effect of α-olefin/ethylene ratio in copolymerization on the content of branchings in copolymers, kinetic profile, copolymer yield, molecular weight and molecular weight distribution of copolymers have been obtain...
متن کاملMechanism and Site Requirements of Thiophene Hydrodesulfurization Catalyzed by Supported Pt Clusters
Hydrodesulfurization (HDS) processes remove sulfur atoms from hydrocarbons by chemical reduction to hydrogen sulfide using H2 with transition metals and their sulfides as catalysts. Mechanistic and structural insights, concerning reaction pathways and catalysts, respectively, are required to design more effective HDS catalysts, with higher rates at lower H2 pressures, so as to meet emerging req...
