摘要

A catalyst for hydrotreating a heavy hydrocarbon oil comprises a carrier which is a calcined composite of a mixture of a clay mineral consisting mainly of magnesium silicate having a double-chain structure and a pseudoboehmite which shows a powder X-ray diffraction spectrum obtained by applying a CuK alpha ray such that the half value width of the peak on the (020) plane is between about 0.8 DEG and 4.0 DEG and the intensity of said peak is between 1.2 and 8.0 times as high as that at 2 theta =10 DEG . At least one catalytic metal component is composited with the carrier, the metal of the catalytic metal component being selected from the group consisting of metals belonging to Groups VB, VIB, VIII and IB of the Periodic Table. Disclosed also are a method of preparing such a catalyst, and a process for the hydrotreatment of heavy hydrocarbon oils containing asphaltenes and heavy metals.
