Fixed bed nickel-aluminum hydrogenation catalyst

Can be used for the catalysis of BDO, 1,4-butanediol (BDO) is an important basic organic chemical raw material with a wide range of uses. Through the two main reactions of dehydration and dehydrogenation, it can be processed into a series of useful chemicals, mainly used in the production of polybutylene terephthalate (PBT), γ-butyrolactone (GBL), polyurethane (PU), N-methylpyrrolidone (NMP), tetrahydrofuran (THF) and polytetramethylene ethylene glycol ether (PTMEG), etc.; especially its derivatives are high value-added chemical products, widely used as solvents, medicine, cosmetics, plasticizers, curing agents, pesticides, fibers, engineering plastics and so on.

In the production process of BDO, many catalysts still rely on *** long cycle and expensive, including a fixed-bed catalyst for high-pressure hydrogenation of BDO. Shandong Jiahong has many years of experience in the production of nickel catalysts and has successfully localized BDO high-pressure hydrogenation catalysts, which greatly reduces the use cost of imported catalysts. The high-pressure hydrogenation catalyst has a long service life, the main reactor is 6-12 months, and the side reactor is 12-24 months. After using the catalyst, the conversion rate of BYD can reach 99.99%, and the product purity of BDO is > 99.7%. The use effect can completely reach the level of imported catalysts.
