Abstract
Described is a catalyst for preparing hydrogen peroxide by an anthraquinone process and for regenerating a working solution and a method of preparing the catalyst. The catalyst contains palladium, magnesium, and cerium components uniformly distributed in alumina. Alternatively, the catalyst contains a palladium component distributed in a ring shape in an alumina sphere and magnesium and cerium components uniformly distributed in the alumina.
