Process and apparatus for catalytic cracking of residual oils

Patent ·
OSTI ID:7261125
This patent describes a process for the catalytic cracking of a heavy, metals laden hydrocarbonaceous feed. The process comprises contacting a hot regenerated catalyst stream with the feed in a base of riser reactor, cracking the feed in the riser reactor at catalytic cracking conditions to form cracked products and coked catalyst containing metals, separating the coked catalyst from cracked products, stripping the coked catalyst with steam and regenerating the steam stripped catalyst regenerator with an oxygen-containing gas to form hot regenerated catalyst.
