Abstract
A feed nozzle assembly located near the bottom of an FCC riser reactor includes a plurality of feed nozzles, each feed nozzle including a discharge end which is angled toward the center of the riser. The angled discharged ends provide a combined discharge of hydrocarbon feed and atomization gas into the central portion of the riser thereby providing a desirable feed/catalyst contact condition while preventing impingement of the feed upon the riser walls.
