摘要：
A hydrogenation catalyst for the production of hydrogen peroxide by the hydrogenation of anthraquinones in accordance with a hydrogen peroxide production process utilizing an anthraquinone method. The catalyst includes palladium supported on a carrier. The carrier comprises spherical silica particles, wherein at least 90 wt % of the silica particles have particle diameters of 10 to 100 .mu.m. The silica particles have an average particle diameter of 30 to 60 .mu.m and a pore volume of 0.4 to 1.0 ml/g. The catalyst has desirable activity, strength, service life and selectivity.
