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.
Claims5
A catalyst applied to a hydrogenation step of producing hydrogen peroxide using an anthraquinone method, wherein the catalyst comprises a palladium component distributed in a ring shape around an alumina sphere and wherein a magnesium component and a cerium component are uniformly distributed in the alumina sphere, and
- wherein the ring shape is 5 to 8 μm away from a surface of the alumina sphere and formed to have a thickness of 10 to 20 μm.
