This invention is directed to a feed injector for a fluid catalytic cracking reaction zone, which feed injector provides improved oil atomization and dispersion. The injector comprises a straight-pass conduit section, in which a feed oil and steam are premixed, and a terminal section, where the oil is atomized and dispersed by a generally fan-shaped distributor. The feed injector produces a substantially flat spray pattern across the direction of catalyst flow in the catalyst/oil contacting section of the catalytic cracking reaction zone. Improved product yield and lower coke and light gas yields are obtained.
