The application provides a regeneration method of halogenated nitrobenzene continuous hydrogenation catalyst, and relates to the technical field of fixed bed halogenated nitrobenzene hydrogenation. The regeneration method mainly comprises the following steps: using alcohol, alkali, petroleum ether and ethyl acetate to preliminarily clean the bed layer, removing azo compounds and other pollutants on the surface of the catalyst by using the special properties of ionic liquids, and then completing the regeneration of the catalyst through the steps of pickling, precious metal solution treatment and drying. The application overcomes the defects of the prior art, has the advantages of simple operation, mild conditions and low cost, realizes the in-situ removal of surface impurities such as reaction intermediates and azo compounds on the catalyst surface without damaging the structure of the catalyst and disassembling the catalyst, further supplements the lost metal active components, and can effectively restore the catalyst activity.

This utility model discloses a hydrogen-rich water device with adjustable hydrogen-water mixing, including a pure water tank, a pure water circulation pump, an electrolyzer, a gas-water separator, and a buffer tank. The electrolyzer and gas-water separator are equipped with an anode, a cathode, and a proton exchange membrane. A motor mounted on the buffer tank drives a high-pressure hydrogen dissolving rod to move left and right. Components such as the insertion plate and assembly plate have specific connections and are equipped with sealing sleeves to prevent interference. This device has dual channels for electrolyzing water and drinking water, allowing the human body to drink different water qualities through a series of processes, improving its practicality. Furthermore, the reciprocating motion of the high-pressure hydrogen dissolving rod driven by the motor increases the contact area between hydrogen and water, forming a flow path and vortex, improving the hydrogen dissolution speed and efficiency, resulting in a more uniform hydrogen distribution, reducing concentration gradients, and improving the quality of the hydrogen-rich water and the overall quality of the device.
