ABSTRACT:
A fluid catalytic cracking process wherein a hydrocarbon charge-stock is atomized and injected, in a contactor/reactor, into a vertical curtain of hot regenerated catalyst to vaporize and crack hydrocarbons in the charge-stock, wherein the catalyst preferably contains at least 40% by weight of a zeolitic cracking component and the contact time of the hydrocarbon vapors and the catalyst in the contactor/reactor is ultra-short, preferably not greater than 0.5 second.
