Ammonium activation of zeolites in the presence of gaseous ammonia |
摘要 |
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.
