Abstract

The invention relates to a multi-channel high-throughput catalyst evaluation device and an evaluation method. The device comprises a feeding system, a reaction system, a cooling system, a sampling analysis system and a product collection system. Catalysts are contained in a reactor. Raw materials enter a mixing unit through a flow control unit for even mixing and enter a multi-channel reactor for reaction. After the reaction is completed, the materials are cooled and then enter a next unit, are sampled and analyzed by the sampling analysis system and enter the product collection system. Gas-liquid separation is conducted to products in a high-pressure separator. Liquid enters a product storage unit for storage. Gas is collected, emptied or correspondingly treated through a gas path. The multi-channel high-throughput catalyst evaluation device and the evaluation method are suitable for simultaneously evaluating various catalysts at the same reaction temperature and under the same reaction pressure, the catalyst screening efficiency is obviously improved, the testing time is saved and the test repeatability is good.

Description

technical field [0001] The invention belongs to the technical field of catalyst research and development process, and in particular relates to a multi-channel high-throughput catalyst evaluation device and evaluation method. The invention is mainly applicable to small-scale test or pilot-scale test in the process of catalyst research and development in petrochemical, pharmaceutical chemical, coal chemical and other chemical processes. Background technique [0002] In petrochemical, pharmaceutical chemical and coal chemical production processes, most of the chemical reactions are realized through the catalysis of catalysts. Therefore, the catalyst is an important catalyst in the chemical production process. The quality of the catalyst determines whether a production process can be realized, and its economy plays a vital role in the chemical production process. [0003] The research and development process of a catalyst generally needs to go through a small scale test, a pilo...
