ABSTRACT:
A process is disclosed for reducing the impact of basic compounds, such as nitrogen, on hydrocarbonaceous feed intended for catalytic cracking. In a preferred embodiment, a portion of the regenerated catalyst of a catalytic cracking process is separated and contacted with the hydrocarbonaceous feed at a temperature and for a time sufficient to strongly bind the basic contaminants in the feed with the separated portion of the acid catalyst. The feed is then passed to the catalytic cracking reactor in a slurry with the separated catalyst, resulting in a desirable conversion increase.
