| titleOfInvention | Revitalization method of hydrogenation catalyst and production method of hydrogen peroxide comprising the same |
| abstract | assignmentn n n n It is used repeatedly in the hydrogen peroxide production plant by the anthraquinone method, and the process of reviving both the selectivity and the activity of the hydrogenation of this catalyst without damaging the hydrogenation catalyst which the selectivity of hydrogenation falls and the generation of by-products increased. It provides a method for producing hydrogen peroxide.n n n n Solutionn n n n According to the present invention, a reduction step of reducing an operating solution containing an organic solvent and anthraquinones with hydrogen in the presence of a hydrogenation catalyst, and a catalyst activating step of activating the hydrogenation catalyst whose selectivity of hydrogenation is reduced by repeated use. A method for producing hydrogen peroxide by the anthraquinone method, comprising the hydrogenation catalyst so that the pH of the catalyst immersion liquid mixed with 5 parts by weight of pure water with respect to 1 part by weight of the hydrogenation catalyst after activation is 8.0 or more. A process for producing hydrogen peroxide, characterized in that the step of treating with a first alkaline aqueous solution having a pH of 10 or more containing an alkali metal and washing with a second alkaline aqueous solution of weak alkali than water or the first alkaline aqueous solution is provided. do.n n n Anthraquinone, hydrogen peroxide |
