Hydrogenation generally uses precious metals as catalysts, such as palladium carbon, Raney nickel, etc., which are expensive and an important part of equipment investment. Catalysts will become deactivated during use and leak out of the reaction system along with the product. Therefore, effective filtration and recovery of catalysts to improve their service life is an important way to reduce costs and increase efficiency in hydrogenation units. A system with functions such as catalyst filtration, product replacement, solvent backwashing, catalyst cleaning, and retirement
Using a metal membrane catalyst filter as the key equipment for filtering catalysts, it has high filtration efficiency and can be completely regenerated, allowing the catalyst to circulate 100% between the reaction system and the filtration system. On the basis of the filter, through process design, all the requirements for treating catalysts can be met, and the operation can be adjusted according to the device requirements. The system is easy to operate, cost-effective, and suitable for various hydrogenation reaction systems.
