A novel solid phosphoric acid catalyst composition is disclosed. The composite comprises solid phosphoric acid and a refractory oxide binder. The composite is characterized in that 25.0 volume percent or less of the total catalyst pore volume consists of pores having a diameter of 10,000 .ANG. or greater. An improvement in catalyst activity and stability is observed when such a catalyst is utilized in a hydrocarbon conversion process.

Solid phosphoric acid catalyst

A hydrocarbon conversion process which utilizes a solid phosphoric acid catalyst having a total X-ray intensity of at least 40 percent relative to alpha-alumina. The solid phosphoric acid catalyst is produced by crystallizing an amorphous mixture of an acid oxide of phosphorus and a siliceous material at a temperature of from 350.degree. to 450.degree. C. and in the presence of from 10 to 50 mole percent water vapor based upon the total vapor rate to the crystallizing means. Embodiments of the new hydrocarbon conversion process include alkylation, oligomerization, and hydration, of hydrocarbons and oxygenated hydrocarbons.

Catalytic condensation process

A solid phosphoric acid catalyst having a total X-ray intensity of at least 30 percent relative to alpha-alumina. The solid phosphoric acid catalyst is produced by crystallizing an amorphous mixture of an acid oxide of phosphorus and a siliceous material at a temperature of from 250.degree. to 450.degree. C. and in the presence of from 3 to 50 mole percent water vapor based upon the total vapor rate to the crystallizing means.
