Palladium resin catalyst is a composite material made of palladium and resin. In organic reactions, palladium resin catalysts are mainly used for hydrogenation and dehydrogenation reactions. The palladium barium sulfate catalyst has a sensitive catalytic effect, which can make organic substances react in a shorter time and bring high efficiency reaction products. This catalyst has high reaction rate, high efficiency and high selectivity, and can effectively purify waste gas, hydrogenate organic compounds and formalize.
