Abstract
A phosphate-Al.sub.2 O.sub.3 material is disclosed wherein the phosphate is homogeneously dispersed throughout, the specific surface area as measured by N.sub.2 BET method is at least about 50 m.sup.2 /g, and the average pore radius is no greater than about 200.ANG.. A method is disclosed for producing the material which comprises forming a precursor material by wet-mixing a phosphate yielding species and an aluminum oxide yielding species which can be aluminum oxide, aluminum hydroxylated oxides, aluminum hydroxide, aluminum alkoxides, and combinations thereof, in amounts sufficient to result in an AlPO.sub.4 content of about 3 to 12 percent by weight in the phosphate-Al.sub.2 O.sub.3, drying and heat-treating the precursor material at a temperature and for a time sufficient to form the phosphate- Al.sub.2 O.sub.3. The material is used as a support for catalyst metals.
