Abstract

Disclosed is a system for fluid catalytic cracking. The system includes a method and means for decreasing and increasing the slip velocity of a hydrocarbon reaction stream to further enhance catalytic cracking of the hydrocarbon within the reaction stream. The system also allows for control of residence time within both a riser and a collection and velocity reducing means to provide for more complete cracking of the hydrocarbon without leading to additional coking of the catalytic cracking catalyst.
