1. Remove acidic substances from transformer oil, lubricants and refrigerants. Activated alumina can remove acidic substances produced during its use. In the manufacture of chlorinated and fluorocarbons, the removal of excess halides and water is necessary for non-corrosive products. 2. Under appropriate conditions, pore size distribution and surface chemistry of activated alumina are helpful to adsorb impurities in hydrocarbons. Activated alumina can effectively adsorb rubber, PS (thermoplastic polystyrene composite), ABS (styrene-butadiene-styrene block copolymer), TPE (polyolefin thermoplastic elastomer) and other products.

TBC (p-tert-butyl catechol) inhibitor to meet product requirements. As for the working principle of the catalytic reaction of activated alumina, it is also introduced in this paper that the working principle of the catalytic reaction of the desiccant is not clear, that is, how the active alumina desiccant works. The work of the carrier of the active alumina desiccant is to improve the heat resistance of the active alumina desiccant by preventing the sintering of the active components in the use process. In the industrial production, it will accelerate the catalysis of the chemical reaction of common substances, which can greatly improve the efficiency of industrial production; thus, it will greatly accelerate the production of China's chemical industry.
