I believe that with the popularization of chemistry, more and more people will understand the truth that it is due to the rapid development of chemical industry technology that we see more and more high-quality skin care products, and people no longer believe in such ignorant and uninteresting advertisements as "natural, no additives" and "I just hate chemistry".r

Most of the hydrogenation reactions are exothermic, and most of them are carried out at high temperatures. The hydrogen and most of the materials used have the danger of ignition and explosion, and some of the materials, products or intermediate products are toxic and corrosive. In case of leakage, reactor blockage and other failures, there is a great risk of fire and explosion. 

The first catalyst production plant in China was the catalyst department of Yongli Asia Plant, which was renamed as Nanjing Chemical Industry Company Catalyst Plant in 1959. In 1950, it started to produce AI type ammonia catalysts, C-2 type carbon monoxide high temperature conversion catalysts and VI type vanadium catalysts for sulfur dioxide oxidation, and then gradually completed the production of various catalysts for ammonia industry. By 1984, more than 40 units had produced catalysts for sulfuric acid, nitric acid and ammonia industries.

No catalyst can catalyze water into oil because catalysts can only catalyze reactions that can actually occur, and they cannot help with reactions that cannot occur in the first place. For example, the ammonia reaction and the oxidation of sulfur dioxide are reactions that can actually occur, but in general these reactions proceed more slowly, so they need the help of a catalyst.
