ABSTRACT:
High gas and coke make due to contamination of a zeolitic fluid cracking catalyst by metal species such as nickel and vanadium during a cracking process is reduced by adding a phosphorus compound to the process. When the catalyst already contains a metals passivating agent or such agents are used in the cracking process further significant reduction in gas and coke make is realized without significant increase in regenerator temperature by adding additional phosphorus.
