| abstract |
The invention discloses a catalyst for the production of hydrogen peroxide by anthraquinone method, a preparation method and application thereof. The catalyst uses silica-modified alumina as a carrier and a Group VIIIB noble metal as an active component, and the Group VIIIB noble metal is selected from the group consisting of At least one of Pd, Rh, and Pt; based on the weight of the carrier, the content of silica is 0.5%-10%; based on the weight of the final catalyst, the content of the active component is 0.1-2 %. The catalyst used in the production of hydrogen peroxide by anthraquinone method has the advantages of less by-products and high hydrogenation efficiency. |
