Abstract

This invention describes a two-stage regeneration zone that has a regenerated catalyst circuit such as the one that results from the mixing of a partially regenerated catalyst with a residual coke rate of between 0.3 and 0.7% and a totally regenerated catalyst with a coke rate that is less than 0.15%. All things being equal, this double-population regenerated catalyst enables the maximization of the LCO yield.
