摘要

The apparatus consists of a fluidised bed reactor with fittings for gas introduction and a retaining system for the immobilised biocatalysts. The fluidised bed reactor is characterised in that the fittings for gas introduction consist of a plurality of segments (3) which have gas emergence openings (5), are arranged on the base (2) of the fluidised bed reactor and are charged with gas alternately or cyclically. It is possible to provide another gas introduction unit in the form of a central gas emergence opening (6) which is directed upwards in the fluidised bed reactor. The process for operating the fluidised bed reactor is distinguished in that sequential opening of the gas introduction openings (5) on the segment-like fittings results in cyclic gas introduction into the reactor. It is also possible to switch from the central gas introduction unit (6) to gas introduction through the segment-like fittings (3) or vice versa.
