Reactivation of metal-contaminated cracking catalysts. |
摘要 |
<p>A process for reactivating a spent, metal-contaminated zeolite-containing cracking catalyst composition comprises the substantially simultaneous contacting with a fluorine compound (preferably NH4F) and a metals passivating agent (preferably a compound of Sb or Ca). The thus reactivated cracking catalyst composition is employed in a catalytic cracking process.</p> |
