A fluidized bed reactor system with one or more fluidized bed reactors for carrying out chemical or physical reactions, at least one reactor thereof being a rapidly fluidized reactor to be operated as a circulating fluidized bed and having, at the upper end, a fluid outlet, a particle separator, and a particle line connected thereto for the purpose of feeding back separated fluidized bed particles into the same or a further reactor, wherein, at least one rapidly fluidized reactor has one or more flow control devices producing reaction zones that are separate from one another, and in order to control the flow conditions into the reaction zones, one or more of these flow control devices are specifically adjustable from outside of the system.

Fluidized bed reactor system

A fluidized-bed reactor system with at least two fluidized-bed reactors, each being a circulating fluidized bed, a particle line with a particle separator for transferring fluidized-bed particles from the first to the second reactor, and a particle line exiting at the lower half of the second reactor for transferring fluidized-bed particles back to the first reactor, wherein, at least in the second reactor, two or more reaction zones separated by one or more flow controllers and that the particle line opens into the second reactor above at least one flow controller.

The present invention relates to a fluidized bed reactor system made up of at least two fluidized bed reactors, comprising at least one main reactor () in the form of a circulating fluidized bed and a secondary reactor () in the form of a circulating fluidized bed, and also a particle line comprising a particle separator for transporting fluidized bed particles from the main reactor into the secondary reactor, characterized in that, in the lower region of the respective reactor, a line () connects the secondary reactor () to the main reactor () for transporting fluidized bed particles.
