Abstract: A catalystic cracking process, using a fluidised catalyst, in which finely-divided catalyst is circulated between a reactor and a regenerator, and the catalyst is regenerated by holding it as a fluidised bed in a gas stream containing oxygen, is improved by (A) removing practically all the particles from the gas stream which leaves the regenerator (B) sorting the particles removed in this way into a fraction consisting of larger particles and a fraction consisting of smaller particles (C) recycling to the cracking process the fraction consisting of larger particles; and (D) expanding the gas stream leaving the regenerator in a gas turbine after the particles have been removed from the gas stream in step A. The larger catalyst particles which are recycled act as a very active catalyst stream which can be used in place of fresh catalyst. The activity of the catalyst can be maintained at low cost.
