The metal-free hydrogenation catalyst provided by the invention is low in price, high in catalytic activity and good in stability, is environment-friendly and can replace a noble metal catalyst and a Raney nickel catalyst in an existing hydrogenation process; a production process is effectively simplified and the cost is reduced; the metal-free hydrogenation catalyst has important practicability and economical efficiency.

Description

technical field [0001] The present invention relates to a catalyst and its application. More specifically, it relates to a metal-free hydrogenation catalyst and its application. Background technique [0002] Catalysts play an extremely important role in the modern chemical industry. Catalysts are used in more than 90% of industrial processes, such as petrochemical, fine chemical, biochemical, pharmaceutical, environmental protection, new energy, etc. Among them, the most commonly used catalysts are metals, metal oxides, metal sulfides, and metal matrix composites. For example, noble metals such as platinum, ruthenium, gold, silver, and palladium are often used in oxygen reduction reactions, Fischer-Tropsch synthesis reactions, carbon monoxide oxidation, carbon dioxide conversion, and selective hydrogenation reactions. With the rapid development of the economy and the continuous improvement of human living standards, the demand for various chemicals in the world has increas...

Problems solved by technology

However, precious metal catalysts have few reserves, are expensive, and have high production costs; although Raney nickel catalysts are relatively cheap, they are easily deactivated and are flammable when exposed to air after hydrogenation, requiring high equipment requirements.

It can be seen that the catalyst has become a bottleneck restricting the further development of catalytic hydrogenation to prepare aromatic amines.
