Abstract
The invention is a method for mixing feedstock with fluidized catalyst in a fluid catalytic cracking (FCC) riser reactor. A dispersed catalyst suspension is passed upwardly at a velocity of 0.5 to 4 ft/sec. Atomized feedstock is injected downwardly at a velocity of -30 to -1000 ft./sec to produce a turbulently mixed reaction suspension. Vaporizing feedstock rapidly accelerates the reaction suspension in approximately plug flow. The slip factor between catalyst and hydrocarbon in the reaction suspension defining the departure from ideal plug flow is thereby reduced.
