  • Patent number: 4558031
    Abstract: A method is described for producing a catalyst or catalyst support having both high surface area, e.g. greater than 150 m.sup.2 /g, and large pore sizes, e.g. greater than 1.0 ml/g of macropores having diameters between 1 and 50 .mu.m. According to the method, a metal oxide is mixed with water and an acid to form a dilute metal gel, preferably containing at least 70% by weight water and consisting of a loose three dimensional network of oxide containing the water evenly dispersed throughout. This gel is slowly dried at a temperature below the boiling point of water whereby a substantial proportion of the water is removed from the interior of the pore structure, leaving the three dimensional network intact. Thereafter, the dried product is calcined to form a novel catalyst or catalyst support having both high surface area and large pore sizes. The novel catalyst is useful as a component of a catalytic cracking catalyst or a hydrocracking catalyst.
