Fluid catalytic cracking feedstock injection process

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 0.15 to 1.22 m/sec (0.5 to 4 ft/sec). Atomized feedstock is injected downwardly at a velocity relative to the...
