Process for preparing zeolite A from spent cracking catalyst |
摘要 |
This invention provides for a method of preparing zeolite A from spent metals-contaminated cracking catalyst while concomitantly removing at least a portion of one of the contaminant and catalytic metals from the spent catalyst by contacting the spent catalyst with a solution containing an alkali metal hydroxide and a sufficient amount of sodium aluminate under hydrothermal conditions for a specified period of time to form the zeolite A.
