High activity and high selectivity: Under mild reaction conditions, the butadiene content in the selective hydrogenation reaction product is less than 8 ppm, and the loss of 1-butene at the outlet is less than 2.5%, with low total hydrogenation and isomerization rate.
High stability: A specific structure catalyst with shell layer internal migration inhibits side reactions such as polymerization, has strong resistance to toxic substances, inhibits the loss of active components, and the catalyst life is more than 5 years.
Environmentally friendly: The catalyst has no harmful components and corrosive components, does not pollute the environment, and is easy to handle.
