Abstract
A process wherein a fluidized particulate solid is contacted with a hydrocarbon feedstock in a vertically extending contacting zone, which process comprises introducing a stream of the particulate solid into the contacting zone and introducing a plurality of streams of liquid hydrocarbon feedstock into the contacting zone to intimately contact the particulate solid therein, the plurality of streams each being introduced into the contacting zone from one of a plurality of nozzles spaced apart in the contacting zone, and each stream having a flow path extending into the contacting zone and a flow pattern having a thickness which is substantially constant and a width which diverges from the point of introduction into the contacting zone. The nozzles each comprise a tubular member having an inlet end, an outlet end, and a flow channel extending through the member from the inlet to the outlet end, the outlet end having an oval concave surface therein and a circular opening centered in the concave surface and in flow communication with the flow channel.
