Abstract
Disclosed is a fluid catalytic cracking apparatus. The apparatus includes 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 apparatus 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.
