Description

Technical Field

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

[0002] The hydrogenation drum reactor is an important chemical equipment, which is mainly used for various types of hydrogenation reactions. These reactions usually involve a chemical reaction between hydrogen and another compound to generate a new compound whose molecular structure contains hydrogen atoms. The hydrogenation drum reactor can provide a high temperature and high pressure environment, so that hydrogen and the compound to be reacted can react chemically in this environment. When the hydrogenation drum reactor is in use, a hydrogen storage system is required to transport hydrogen, and there may be moisture and oxygen in the hydrogen when it is in the storage system. Although a series of treatment steps are usually performed before storage to remove moisture and oxygen in the hydrogen as much as possible, moisture and oxygen may still enter the storage system due to various reasons (such as the sealing of the storage container, environmental humidity, oxygen permeation, etc.). Therefore, directly transporting hydrogen with high moisture and oxygen content into the reactor will easily form an explosive mixture. Secondly, moisture and oxygen may react with the catalyst in the reactor, causing the catalyst to be poisoned or deactivated, reducing its catalytic activity. In addition, moisture may also participate in some side reactions to generate undesirable products and reduce the purity of the target product. There are certain shortcomings. Utility Model Content
