The properties of the heteropoly acids, 12-molybdophosphoric acid, 12-tungstosilicic acid, and 12-tungstophosphoric acid, and the dimeric 9-tungstophosphoric acid have been examined. The conversion of methanol to hydrocarbons has been employed as a test reaction for the activity and selectivity of these catalysts. The effects of variations in reaction temperature, calcination temperature, and environment (air, helium, hydrogen), and residence time have been studied, and the catalysts have been characterized by measurements of surface area, pore size distributions, X-ray powder diffraction, and the chemisorption of ammonia.
