Fixed-bed hydrogen peroxide catalyst

摘要

An improved fixed-bed cyclic anthraquinone process for production of hydrogen peroxide wherein the improvement is using a hydrogenation catalyst comprising palladium or a mixture of palladium and platinum on a support containing alpha alumina. The preferred range of palladium is 0.1 to 3 weight percent and the preferred range of platinum, when present, is greater than 0.01 weight percent (based on the total weight of the catalyst). The preferred catalyst support contains greater than 5 percent alpha alumina.
