Abstract

A method for dividing a stream of solids includes discharging the stream of solids via a first downer. The stream of solids are fluidized at a bottom of the first downer by supplying a first conveying gas. By the first conveying gas, a part of the stream of solids are conveyed to a top of a first riser branching off from the first downer. A remaining part of the stream of solids are discharged via a second downer adjoining the first downer. The remaining stream of solids are fluidized at a bottom of the second downer by supplying a second conveying gas. By the second conveying gas, a part of the remaining part of the stream of solids are conveyed to a top of a second riser branching off from the second downer.
