Process for catalytically cracking feedstocks paraffin rich comprising high and low concarbon components

摘要

A process for contemporaneously catalytically cracking a paraffin rich feedstock and a heavy feedstock wherein the feedstocks are segregated prior to catalytic cracking in separate reactors with regenerated particulate catalyst solids. The process provides for the separate optimal cracking of paraffinic constituents and heavy naphthenic constituents while maintaining an overall heat balance.
