TREATMENT OF ZEOLITES |
| 摘要 |
<p>A method of preparing catalysts which exhibit enhanced hydrocarbon conversion activity which comprises calcining a zeolite such as ZSM-5 at temperatures ranging from about 600 to about 1300 DEG C and subsequently activating it by exposing it to a mixture of ammonia and steam at temperatures ranging from 100 to 1000 DEG C to the extent that at least about 10% crystallinity is preserved in the resulting activated catalyst.</p> |
