Abstract

A feed nozzle assembly (100) for introducing steam and a heavy petroleum hydrocarbon into a catalytic cracking reactor, comprising: (a) a nozzle body (101) having an inner tube (105) defining a gas conduit (106) and an outer tube (115), wherein the inner tube (105) and the outer tube (115) define an annular liquid conduit (116), and wherein each of the tubes (105, 115) have an inlet end (120, 125) and an opposite outlet end (130, 135); (b) a first nozzle tip (140) fixedly attached to the outlet end (130) having a dome-shaped outlet end (142) provided with at least one passageway (145); (c) a second nozzle tip (150) fixedly attached to the outlet end (135) having a dome-shaped outlet end (152) provided with at least one elongated slit (155), which dome-shaped outlet end (152) of the second nozzle tip (150) extends beyond the dome-shaped outlet end (142) of the first nozzle tip (140).
