摘要：<p>In a process for returning finely dispersed solids discharged from a reactor vessel (1) with a carrier gas through a discharge point (2) of the reactor vessel (1) to a return point (15) of the reactor vessel (1), the solids are separated in a solid separator (4), in particular a cyclone separator, then returned with a carrier gas to the reactor vessel (1) while a differential pressure is maintained between the solid separator (4) and the return point (15). When the solids enter the reactor vessel (1), they are at least partially gasified and/or burned with oxygen supplied for that purpose. To enable the solids to be returned without moving parts which would be exposed to abrasion, in a continuous and controlled manner, the separated solids are directly and continuously aspirated by the solid separator (4) by means of a propellant gas and by an injector effect, accelerated and supplied to the reactor vessel (1).</p>
