Hydrodesulfurization of thiophene has been studied over alumina supported sulfided molybdena, nickel-promoted molybdena and over nickel (Mo, NiMo and Ni) catalysts. The experiments were carried out with a mixture of thiophene, labeled with radioactive carbon (thiophene-[G-]-14C) and of non-radioactive tetrahydrothiophene (1:1 mol ratio) in a micro catalytic system. It was established, that the main products were tetrahydrothiophene-14C, 1-butene-14C, 2-butene-14C, butane-14C… 


Conversion of thiophene on molybdena–alumina catalysts containing Group 8–10 metals: effect of H2S uptake
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
The particular characteristics of the active sites of MoS2, WS2 catalysts in thiophene hydrodesulfurization
It was reported in earlier studies that a linear correlation existed between the total sulfur exchange capacity and thiophene hydrodesulfurization activity of different, alumina- or silica-supported
Catalytic hydrodesulfurization of thiophene. VII. Comparison between thiophene, tetrahydrothiophene, and n-butanethiol
The desulfurization rates in hydrogen of thiophene, tetrahydrothiophene, and n-butanethiol over molybdenum disulfide, an alumina supported cobalt molybdate, and a chromia catalyst have been
Promoter effect of nickel in thiophene hydrodesulfurization as monitored by sulfur uptake and cyclohexane conversion
Hydrodesulfurization (HDS) activity and activation energy (ε′TH) values were determined and compared with irreversible sulfur uptake (Sirr) by 5 Al2O3-supported (MoOx, Ni and three NiMoOx) catalysts
Hydrodesulfurization of dibenzothiophene catalyzed by sulfided CoO-MoO3γ-Al2O3: The reaction network
Kinetics experiments have determined the reaction network in the hydrodesulfurization of dibenzothiophene catalyzed by sulfided CoO-MoO3/γ-Al2O3 at 573°K and 102 atm. The predominant reaction is a
