Abstract
Rapid cooling of a gas with simultaneous heat recovery is accomplished by directly contacting the gas with finely divided solids, and then recovering heat from the finely divided solids by passing the solids through at least two separate compartments where the solids are maintained as a fluidized bed, with heat being recovered therefrom by indirect heat transfer between a heat transfer fluid and the heated solids in the fluidized beds. Pyrolysis effluent may be rapidly quenched while providing for effective heat recovery.
