Description

Technical Field

[0001] The utility model relates to the technical field of hydrogenation reactors, in particular to a hydrogenation reactor convenient for catalysis. Background Art

[0002] In the chemical industry, hydrogenation reactors play a vital role, especially in oil processing, chemical synthesis, and hydrogen energy production. The main function of a hydrogenation reactor is to change the properties of reactants through catalytic hydrogenation reactions to obtain the desired products. However, existing hydrogenation reactors still have some problems and challenges in the catalytic process.

[0003] In the catalytic process, traditional hydrogenation reactors have low reaction efficiency and unstable product quality due to uneven distribution of catalysts or insufficient activity. In addition, during long-term use, the activity of the catalyst will gradually decrease due to carbon deposition, poisoning and other reasons. Therefore, it is often necessary to replace it to avoid affecting the reaction efficiency. At the same time, the internal components of the existing reactors are not designed reasonably, which may cause uneven fluid distribution and insufficient contact between the reactants and the catalyst during use, thereby affecting the reaction effect. In order to solve the above problems, while changing the distribution of the catalyst inside the hydrogenation reactor, it is convenient to replace and install the catalyst inside the reactor, thereby reducing the replacement time, improving the reaction efficiency, and making it more convenient to use the hydrogenation reactor. For this reason, we propose a hydrogenation reactor that is convenient for catalysis. Utility Model Content
