Abstract

In a fluidized bed process having a bed of fluidized particulate material which is susceptible to having at least some of the particulate material being entrained in the gases exiting the bed, the entrainment is reduced by introducing the particulate material into the process, in the substantial absence of a gas which transports the particulate material, at one or more points which are below the surface of the bed of fluidized particulate material.
