Process for preparing hydrotreating catalysts prepared from hydrogels and catalysts thus prepared.

摘要

Process for preparing wide-pore catalysts prepared by incorporating a metals solution containing an element selected from the group consisting of molybdenum, tungsten and mixtures thereof, and an element selected from the group consisting of nickel, cobalt and mixtures thereof, into a phosphated alumina hydrogel support prepared in the presence of a methanol and/or ethanol containing solution. The final calcined catalysts have surface areas greater than 300 m<2>/g, crush strengths greater than 40.5 N and more than 20% of their pores greater than 15 nm.
