ABSTRACT:
A novel phospha-alumina gel having a large average pore diameter and a characteristic pore volume distribution is prepared by co-precipitation of aluminum and phosphorus compounds. The gel is then dried, formed and calcined to give a material having a large average pore diameter of at least 100 A and a characteristic pore volume distribution with a minimum number of small pores, such that less than 30% of the total pore volume is in pores smaller than 100 A in diameter. Such material is especially useful as a catalyst or as a catalyst support.
