A nozzle apparatus is described for injecting a liquid hydrocarbon feedstock into a catalytic conversion zone which comprises: (a) at least two confined passageways arranged to provide parallel fluid flow; (b) a first flow restriction means concentric with an affixed to the downstream end of each confined passageway; (c) at least two annular passageways, each of the annular passageways having a detached confined passageway extending longitudinally through a portion thereof in concentrically spaced relationship (d) a second flow restriction means concentric with and affixed to the upstream end of each annular passageway; and (e) a third flow restriction means wherein the confined passageways communicate with each other at the upstream end by means of a first common flow space defined at the downstream end of the first common flow space by the third flow restriction means. The first common flow space contains therein means for deflecting the liquid hydrocarbon feedstock entering the first common flow space.
