Abstract: There is provided a method for preparing an acidic solid oxide having a reduced particle density, where the acidic solid oxide comprises a Group IVB metal oxide modified with an anion or oxyanion of a Group VIB metal. An example of this acidic solid oxide is zirconia modified with tungstate. The acidic solid oxide having a reduced particle density is prepared by coprecipitating the Group IVB metal oxide along with the anion or oxyanion of the Group VIB metal in the presence of a salt. This acidic solid oxide is particularly effective as a paraffin isomerization catalyst.

Abstract: Alumina-composited zeolite catalysts are activated by contact with an aqueous ammonium solution under ammonia gas pressure such that a pH of at least about 8 is maintained in the solution. The treated zeolite may thereafter be calcined without prior ammonium-exhange to provide the zeolite in the hydrogen form. Catalysts which are activated in this manner are useful for converting alcohols and/or ethers to hydrocarbons including aromatics.
