摘要
PURPOSE: A palladium catalyst supported on an alumina xerogel support with controlled acidity and a method for preparing -butyrolactone based on the hydrogenation of succinic acid using the catalyst are provided to thermo-chemically stabilize a catalytic process by optimally combining the acid characteristic of the support and the hydrogenation activity of palladium. CONSTITUTION: A palladium catalyst supported on an alumina xerogel support with controlled acidity is obtained by gelating an aluminum precursor based on a sol-gel method and implementing a thermal treatment. The average pore size of the palladium catalyst is between 2 and 10nm. The surface area of the palladium catalyst is between 100 and 300m^2/g. The temperature of the thermal treatment is between 700 and 900 degrees Celsius. 1-10 parts by weight of the palladium catalyst is supported by 100 parts by weight of the alumina xerogel support.
