Abstract
Described is a catalyst obtained by supporting magnesium and cerium on activated alumina, firing same to immobilize the metals, and then impregnating same with palladium and performing reduction thereon, and is applied, when hydrogen peroxide is prepared by means of an anthraquinone process, to operation solution regeneration or hydrogenation, and thus an efficient regeneration conversion rate or synthesis yield is achieved.
