Abstract
A fluid catalytic cracking (FCC) process and apparatus using a riser and a reactor for cracking of petroleum feeds in the presence of a catalyst and a regenerator for regenerating the spent catalyst are improved by providing a downflow riser. The downflow riser assures uniform distribution of the catalyst throughout the feed, decreases contact time of the catalyst with the feed and decreases the amount of coke made in the process.
