Hydrodesulfurization of coker feed
Chemistry and Technology of Fuels and Oils, 1983This article presents data on the hydrodesulfurization of heavy coker gasoils, a distillate from the tar obtained in the thermal cracking of resid, heavy vacuum gasoil (350-520/sup 0/C), and blends of these stocks in various ratios. A single-pass flow unit was used with a fixed bed of commercial alumina-cobaltmolybdenum catalyst.

Sorption on hydrodesulfurization catalysts
Journal of Catalysis, 1979Abstract The adsorption of hydrocarbons, thiophenes, esters, acids, and anilines on MoS2 and on sulfurized CoMoAl2O3 and Al2O3 catalysts has been investigated by a chromatographic method at 200 °C. The polarity of catalysts, estimated from differences in the adsorption of alkanes and aromatic hydrocarbons, decreases in the order Al2O3 > CoMoAl2O3

Hydrodesulfurization on MoS2/MgO
Catalysis Letters, 1991A series of Mo/MgO catalysts with loadings ranging from 2–12 wt% Mo were studied by oxygen chemisorption, X-ray diffraction and activity for thiophene hydrodesulfurization (HDS) reaction. The results obtained from the above measurements are compared with those on Mo/-γ-Al2O3.

Kinetics of dibenzothiophene hydrodesulfurization
Journal of Catalysis, 1991Hydrotreating is a process in which organically bound sulfur and nitrogen compounds are removed from petroleum feedstocks to produce processible, stable, and environmentally acceptable liquid fuels or lubes. Essentially two types of catalysts, which differ in composition, are in use in current refineries: one is sulfided CoO-MoO{sub 3}/{gamma}-Al{sub 2}
