AMMONIUM ACTIVATION OF ZEOLITES IN THE PRESENCE OF GASEOUS AMMONIA |
| 摘要 |
<p>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-exchange to provide the zeolite in the hydrogen form.</p> |
