Problems solved by technology

This kind of reaction device often needs to dissolve hydrogen in the raw material liquid first, and then pass it into the reactor to react under the action of the catalyst, which increases the hydrogen dissolution link, prevents the flow of gas from interfering with the distribution of the catalyst, and has a large limit on the gas-liquid flow rate , and because it is equipped with a high-power electromagnetic coil, the cost is relatively high

Description

technical field [0001] The invention belongs to the technical field of chemical technology and equipment, and relates to a slurry bed continuous hydrogenation reaction device and method. Background technique [0002] Hydrogenation reaction is an important chemical reaction, and the products of hydrogenation reaction are various and widely used. This type of reaction generally uses liquid raw materials to react with hydrogen, and metal particles are used as catalysts. Therefore, the mass transfer of gas, liquid, and solid in the reaction system is the key to the reaction. Stirred tank type batch hydrogenation process is often used in industry. The reaction temperature is 100-180°C and the pressure is high. When the catalyst particles are small, the catalyst cannot be evenly distributed in the reactor by stirring, resulting in three-phase transmission of gas, liquid and solid. The quality and effect are poor, the reaction time is long, and side reactions often occur; after th...
