Abstract

In fluidized catalytic cracking, enhanced efficiency is produced through the use of a spray nozzle having two transversely elongated discharge orifices for effecting fine atomization of liquid hydrocarbon feed as the latter is sprayed from the nozzle. The orifices preferably are inclined so as to produce a converging spray but can be inclined to produce a diverging spray or a substantially flat spray.
