Abstract

The chromatographic reactor includes three or more packed columns cascaded successively. The inlet end of each packed column is connected via a separated switch-type valve to the inlet pipe for material liquid to enter and the inlet pipe for eluting liquid to enter; and the outlet end of each packed column is connected via a separated switch-type valve to the outlet pipe for residual liquid with enriched weak sorptive component from reacted product to drain and the outlet pipe for extracting liquid with enriched strong sorptive component from reacted product to drain. By means of controlling the switch state of the valves, the present invention performs, chromatographic separation and reaction simultaneously, so that the reactor can run continuously with high reaction converting rate and high produce separating efficiency. The present invention is especially suitable for chromatographic separation course of different products and of product and reactant.

Description

technical field [0001] The invention relates to a reaction separation coupling device containing a catalyst and an adsorbent for liquid treatment, in particular to a simulated moving bed chromatographic reactor. Background technique [0002] In the application fields of chemical industry, medicine, biology and fine chemical industry, there are generally a series of separation devices in the downstream of the chemical reactor or biochemical reactor to cooperate to form the whole process, and these separation devices mainly use physical methods to realize the reaction products and reactants. The separation, and the purification of the reaction product is realized, so as to obtain the product that meets the quality index. However, in the case of reversible reactions or reaction by-products that can poison the catalyst, this type of process has disadvantages such as low reaction conversion rate, low product yield, low separation efficiency, and low prod...
