ABSTRACT:
A composition of matter is prepared by a process comprising the steps of impregnating a alumina-containing support material with a thiosulfate (preferably ammonium thiosulfate), drying the thus impregnated material, impregnating the dried material with a transition metal compound, drying and calcining the transition metal impregnated material. This composition of matter is used as catalyst composition for hydrogenating unsaturated hydrocarbon compounds, and as catalyst composition for hydrotreating hydrocarbon-containing feed streams (in particular heavy oils) which contain metal and sulfur compounds as impurities.
In another embodiment, a hydrotreating process comprises contacting hydrocarbon-containing feed stream (in particular heavy oils), which contains compounds of sulfur and metals, in the presence of a fixed catalyst bed comprising (X) at least one layer of impregnated substantially spherical alumina-containing particles, which have been prepared by a process comprising the steps of impregnating a specific starting material with (NH.sub.4).sub.2 S.sub.2 O.sub.3 and then heating the thus impregnated material at about 500.degree.-900.degree. C. for improved crush strength retention. In a preferred embodiment, the fixed catalyst bed further comprises at least one layer (Y) of catalyst particles comprising a refractory inorganic carrier and at least one hydrogenation promoter. A composition of matter comprising the impregnated, spherical alumina-containing particles described above, and a process for preparing them are also provided.
