Abstract
Disclosed is an apparatus and process for controlling space velocity in a fluidized catalytic conversion reactor. The catalyst flux rate can be adjusted during the process of the reaction to adjust the space velocity and maintain a fast fluidized flow regime therein. The set parameter in the reactor may be pressure drop which is proportional to catalyst density.
