Anthraquinone hydrogenation catalyzer of anthraquinone method oxydol preparation process and its preparation method

Abstract

The invention discloses a novel catalyst and process of preparation for anthraquinone hydrogenation in hydrogen dioxide solution preparation, wherein the catalyst comprises nickel, boron, metallic additive M and carrying agent S, the specific surface is 200-1200 m2g-1, the active specific surface is 0.1-50 m2g-1. The catalyst preparing process comprises the steps of charging surface activator in the nickel-boron alloy preparation, producing mixture of mesopore or micropore molecular sieve and nickel-boron alloy, the conventional immersion or reducing agent immersion method can be employed to load the nickel-boron alloy onto the common carrying agent or mesopore and microporous molecular sieve.

Description

technical field

[0001] The invention belongs to the technical field of chemical industry, and in particular relates to a novel catalyst used for hydrogenation of anthraquinone in the process of preparing hydrogen peroxide by an anthraquinone method and a preparation method thereof. Background technique

[0002] Hydrogen peroxide is a very important chemical product with a wide range of applications. It has the function of sterilization and disinfection, and the 3% hydrogen peroxide solution can be used for the disinfection treatment of medical equipment. The final product of its reaction is mainly water, which will not pollute the environment. Therefore, in processes such as wastewater treatment and pulp bleaching, the use of hydrogen peroxide can reduce secondary pollution such as a large amount of trihalomethanes caused by the use of chlorine gas as a disinfectant. things. Because hydrogen peroxide has little damage to fiber strength, the treated fabric is not easy to tu...
