ABSTRACT:
An apparatus for catalyst/oil mixing in a catalytic cracking unit comprises a bifluid nozzle for atomizing oil having an outer tube with an end connected to the sidewalls of a coaxial inner tube forming an annulus therebetween, and apertures through the inner tube for mixing steam introduced into the annulus with oil introduced into the inner tube. The inner tube has an end protruding past the end of the outer tube with a cap having a slot affixed to the end of the inner tube, and a plate baffle mounted inside the inner tube and extending partially thereacross near the apertures. The apparatus further comprises a means for providing a flow of cracking catalyst particles along an exterior surface of the cap so as to sweep the length of the slot.
