Treated alumina material for fixed hydrofining beds. |
摘要 |
<p>A hydrotreating process comprises contacting a substantially liquid hydrocarbon-containing feed stream, which contains compounds of sulfur and metals (preferably Ni and/or V), in the presence of a fixed catalyst bed comprising (a) at least one layer of impregnated substantially spherical alumina-containing particles which have been prepared by a process comprising the steps of impregnating specific starting material with at least one dissolved magnesium compound and then heating the thus impregnated material at abut 500-900 DEG C for improved crush strength retention. In a preferred embodiment, the fixed catalyst bed further comprises at least one layer (b) 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.</p> |
