Hydrogenation reactor as the most important equipment in the organic chemistry laboratory use and practical production area, can not only be used as the vessel of the hydrogenation reaction, but also be used as the area for the liquid and gas fully mixing. As the fundamental equipment for the product development, organic chemical product and drugs researching, hydrogenation reactor can also be used for the quantitative analysis of the catalyst activity in the industrial process. This project completion smoothly represented that WHCM had reached another new high level in the hydrogenation reactor fabrication field.
