Abstract
A process is disclosed for the catalytic cracking of hydrocarbons in a fluidized bed wherein the catalyst particles are injected in a fully fluidized suspension into an elongate reaction zone. In accordance with the process, the feedstock to be cracked is injected in a state of small droplets less than 200 microns in diameter countercurrently to the flow of the fully fluidized suspension of catalyst particles.
