Zusammenfassung:The invention discloses a preparation process of high-purity hydrogen peroxide. The process comprises the steps of weakly acidic anthraquinone working solution preparation, nano-palladium catalyst preparation, catalytic hydrogenation, oxidation, extraction, post-treatment, and the like. According to the invention, the carbon-nanotube-loaded nano-palladium catalyst is used for catalysing normal-pressure hydrogenation of 2-ethylanthraquinone. The catalyst has high activity, and is easy to recycle. The catalyst can be repeatedly used, and has a good stability, such that catalyst dose can be greatly reduced. Ananthrahydroquinone microchannel reactor oxidation technology is adopted, and working solution retention time can be reduced to within 1min. The ananthrahydroquinone conversion rate reaches 95%, and the oxidation reactor volume is greatly reduced, such that the production efficiency and the working solution utilization rate are improved.
