ABSTRACT:
Hydrotreating catalysts are made on supports having a core of alumina having predominantly micropore structure, surrounded by a rind of different alumina having at least 25% of total pore volume in macropores. The catalyst support material is impregnated with catalytic metals, e.g. molybdenum with cobalt or nickel or both. The rind captures metals removed from the oils being treated to prevent deactivation of the core by such metals.
