Abstract

In a process for recycling fine-particle solids (4) discharged from a reactor vessel (1) at a discharging position of the reactor vessel (1) by means of a gas, at a recycling position (16) of the reactor vessel (1), the solids (4) are separated in a solids separator (3) and subsequently collected in a collecting vessel (8) and from the same are recycled into the reactor vessel (1) by means of a conveying gas. To enhance the operation of the solids separator (3), but without causing an additional load on the reactor vessel (1), an additional gas stream (23) independent of the gas stream in the reactor vessel is conducted through the solids separator (3) in a circuit, in the direction of flow of the solids (4).
