Abstract:
PCT No. PCT/EP95/02132 Sec. 371 Date Nov. 21, 1996 Sec. 102(e) Date Nov. 21, 1996 PCT Filed Jun. 2, 1995 PCT Pub. No. WO95/33562 PCT Pub. Date Dec. 14, 1995The invention relates to a hydrocracking catalyst containing at least one hydrogenation metal component, and particles of a cracking component of which at least 50% of the outer surface is coated with a layer of a pre-formed oxide, which layer has a thickness in the range of 10 nm to 5 mu m. The cracking component is either a zeolitic cracking component or an amorphous cracking component or a mixture of both. The particles may be coated with oxide by contacting uncoated particles having a mean particle size in the range of 0.1 to 10 mu m with an aqueous medium containing particles of the oxide to be provided as the coating having a particle size in the range of 10-5000 nm, with the ratio between the oxide particle size and the mean particle size of the cracking component particles being in the range of 0.001:1 to 0.5:1. The coating oxide is preferably alumina or silica/alumina.
