Hydrogenation reactor is the kind of high-temperature and high-pressure pressure vessel which is widely used for hydrogenation reaction, or in the occasion where liquid and gas need to be mixed adequately.  It is the necessary equipment in the process of organic chemistry laboratory and petrochemical industry. Hydrogenation reactors are often used to convert residuum, a heavy part of the petroleum industry that is most difficult to use, into light oil to produce gasoline and diesel. Hydrogenation reactor also has a wide range of applications in chemical pharmacy. It can be used as the basic equipment for product development, organic chemical and pharmaceutical research, and can also be used for quantitative analysis of catalyst activity in industrial processes.
