Abstract
A process for the substantial homogenization of the mixture of hot solid particles and of the hydrocarbon vapors to be treated within a tubular reactor (preferably an FCC unit) for the cracking of hydrocarbons in a fluidized bed of hot solid particles. Directly downstream of the zone of injection, in the reaction zone of the feedstock to be or being treated, usually where at least 75 percent of the droplets of the feedstock are vaporized, there is injected into the reactor a fluid in the gaseous state at one or more points on the interior surface of the side wall of the reactor.
