APPARATUS AND METHOD FOR INVESTIGATING DISCONTINUOUS PRODUCT FLUID STREAMS IN THE REACTION OF REACTANT FLUID STREAMS OVER SOLID CATALYSTS

摘要

The invention relates to an apparatus and a method for investigating solid catalysts and processes in which discontinuous fluid streams arise. The apparatus according to the invention which is preferably configured for parallel investigation of a plurality of catalysts comprises at least one reaction space, wherein every reaction space has one or more fluid mixing spaces connected downstream of it. The outlet line of the fluid mixing space or else the outlet line of a sequence of fluid mixing spaces is operatively connected to a throttle element (11), wherein the throttle element (11) is operatively connected to an analyzer and an outlet line and the outlet line comprises a control means. The method according to the invention is operated in a cyclic mode in which at least one product fluid is supplied into the at least one fluid mixing space in a controlled manner, the product fluid stream is commixed in the mixing space and the at least one commixed product fluid stream is supplied to the outlet line and the analyzer. One cycle has a duration in the range from 0.2 to 7200 seconds and can comprise two or more phases of different compositions. The method can comprise a plurality of cycles.
