Abstract
Hydrogenation catalyst is the core for the production of hydrogen peroxide(H2O2)through the anthraquinone route,which determines the production capacity and cost to a large extent,and thus it has always been the research spot and one of the key topics that needs to be studied. A hydrogenation catalyst with high activity,selectivity,and stability not only enhances the production efficiency,but also significantly decreases the formation of the degradation products derived from anthraquinone,and thus reduces the production cost. Herein,advances in the nickel and palladium-based catalysts for the hydrogenation of anthraquinone are reviewed , with special emphasis on the Al2O3-supported palladium-based catalysts. The effects of physical properties,surface acidity,and modification of the Al2O3 support on the catalytic performance of palladium-based catalysts are reviewed. In addition,the recently developed novel palladium-based hydrogenation catalysts are also introduced. Finally,it is concluded that egg-shell palladium catalyst with large surface area and pore size,medium acidity and palladium penetration depth,and modified by proper additive(s),is the ideal catalyst for anthraquinone hydrogenation.关键词
