Abstract
In a fluidized catalytic cracking (FLC) type unit for contacting of a hydrocarbon feedstock with hot solid particles in a fluidized bed in an upright tubular-type upflow hydrocarbon conversion reactor, there is provided, between the means for fluidization and the means for injection of the feedstock, a means for causing the fluidized phase at the periphery of the reactor to rotate about the axis of the reactor.
