Zusammenfassung:	An improved process for producing hydrogen peroxide by the anthraquinone process, utilizing a palladium on calcined support catalyst having high attrition resistance, is provided. An improved anthraquinone slurry process for the production of hydrogen peroxide, the improvement comprising utilizing in the hydrogenation stage of said process a catalyst of palladium on a support consisting essentially of (A) 0.2-10% by weight of metallic palladium and (B) a calcined gamma alumina support having greater than 90% of the alumina in the gamma crystalline phase, said support having pore diameter of 50-1000 , volume average particle size of 1-200 microns, BET surface area of 20-200 m2/g and an attrition resistance of greater than 90%.
