ABSTRACT:
This invention relates to a process for preparing catalyst supports with a wide pore size distribution by simultaneously titrating an acid aluminum species and a basic aluminum species, and interacting the precipitate with a phosphorus-containing oxide during the aging step. The porous resulting alumina supports have surface areas above about 300 m.sup.2 /g with a significant fraction of the pores having diameters greater than 350 .ANG. and a significant fraction of the pores having diameters less than 70 .ANG..
