Hydrodesulfurization (HDS) of thiophene was studied over Co-Mo/Al2O3 catalysts of various composition. Sulfidation was carried out by the reactant itself, alternating with dimethylsulfoxide. Mo-rich catalysts reached their maximum activity level when

The uptake of 35 S -labelled H 2 S, the thiophene hydrodesulfurization (HDS) activity in pulse and flow system and the acidity measured by infrared (IR) band intensities of adsorbed pyridine were studied after various treatments over NiW/amorphous si

A radioactive - pulse-flow - method has been developed for measuring H 2 S uptake by catalysts in a flow system during H 2 S/H 2 purging. As opposed to the classical pulse procedure, the S/(Ni+W) values calculated from radioactivity data obtained in

The effect of H2S on the activity and selectivity of catalysts (Ru/Al2O3, Pd/Al2O3 and Ru and Pd promoted molydena-alumina) was different (on differnt catalysts and different conversions of cyclohexene). Ru-containing catalysts showed higher sulfur s

The uptake of radioactive hydrogen sulfide in a hydrogen stream by MoOx/Al2O3 alone, and by catalysts containing Co, Ru, Pd, Ir and Pt was studied. The amounts of the uptake differ for different catalysts, whereas the ratio of strongly bonded sulfur

The uptake of H2S has been determined for Al2O3 supported Mo, RuMo and PdMo catalysts, exposed previously to cyclohexanol, cyclohexene or thiophene. The amounts of H2S-uptake were compared with those taken up by catalysts treated with H2S only. Signi

Sulfieded MVIII-promoted Mo/Al2O3 catalysts are widely used in hydrotreatment reactions [1–3]. A synergic effect found between catalytic activity of MVIII-metal and Mo was explained by some authors [4–6] by charge transfer between these metals.

Ageing and the effect of H2S on the activity and selectivity of Co-, Ru-, Pd-, Ir-and Pt-promoted and unpromoted MoOx–Al2O3 catalysts have been studied in relation to decomposition of thiophene. The overall activity increased on unpromoted and Pd-p

The uptake of sulfur reduces the overall activity of PtMo/Al2O3 and enhances that of CoMo/Al2O3 in conversion of cyclohexanol. Significant changes in selectivity indicate the existence of different active sites of the initial catalyst for hydro-dehyd
