Properties:
Hydrogenation catalyst is used in addition to product production processes , also widely used in the refining process of raw materials and products. It is divided into three categories according to different hydrogenation conditions: ① Selective hydrogenation catalysts, such as ethylene and propylene obtained from the cracking of petroleum hydrocarbons when used as polymer raw materials, must first undergo selective hydrogenation to remove acetylene, diene, carbon monoxide, carbon dioxide, and oxygen. and other trace impurities without any loss of alkene. The catalyst used is generally palladium, platinum or nickel, cobalt, molybdenum, etc. loaded on nano-alumina. By controlling the amount of active material, the carrier and the manufacturing method of the catalyst, selective hydrogenation catalysts with different properties can be obtained. Others, such as the refining of pyrolysis gasoline and the hydrogenation and reduction of nitrobenzene to aniline, also use selective hydrogenation catalysts. ②Non-selective hydrogenation catalyst, that is, a catalyst used for deep hydrogenation into saturated compounds. For example, the nickel-nano aluminum oxide catalyst is used for the hydrogenation of benzene to produce cyclohexane, the skeleton nickel catalyst is used for the hydrogenation of phenol to produce cyclohexanol, and the hydrogenation of adiponitrile to produce hexamethylenediamine. ③Hydrogenolysis catalyst, such as using copper chromite catalyst to hydrogenolyze grease to produce higher alcohols, etc.
According to many experiments by the manufacturer, the most suitable nano-aluminum trioxide as a catalyst carrier is produced by the aluminum alkoxide method.
The production of nano-aluminum trioxide by the aluminum alkoxide method is a wet production with high chemical purity. The purity is as high as above. It is not easy to cause catalyst poisoning and ensures a high level of catalytic activity
At the same time, the aluminum alkoxide method is produced. Phase nano-alumina has a large specific surface area and pore volume, and can function well as a carrier to load metal for a short time.
