Evaluation device and evaluation method for hydrogen peroxide hydrogenation catalyst prepared by using anthraquinone method

Abstract

The invention discloses an evaluation device and an evaluation method for a hydrogen peroxide hydrogenation catalyst prepared by using an anthraquinone method. The evaluation device comprises a reactor, a hydrogen supply end, a nitrogen supply end, a super constant-temperature water bath, a material receiving end, a blowoff valve, an exhaust tube and a connecting pipe, wherein the reactor is provided with a circulation bypass tube, a three-way connection valve and a sand core filtering plate; gas quality flowmeter controllers for regulating and controlling gas flow are respectively arranged at the hydrogen supply end and the nitrogen supply end, and are connected with a port of the three-way connection valve of the reaction device through connecting tubes; the blowoff valve is connected with the reactor through the exhaust tube; a circulation heater is connected with the reactor through the connecting tube. The evaluation device has the advantages of being simple to operate, good in gas-liquid mixing effect, visible in reaction effect, high in safety, high in controllability and the like, and is applicable to rapid and accurate evaluation on hydrogenation catalysts in laboratories.

Description

technical field [0001] The invention discloses an evaluation device and evaluation method for hydrogen peroxide hydrogenation catalyst prepared by anthraquinone method, belonging to the field of chemical technology and equipment. Background technique [0002] Hydrogen peroxide (H 2 o 2 ), also known as hydrogen peroxide, is one of the main basic chemical products in the world. As an oxidizing agent, bleaching agent, disinfectant, polymer initiator and crosslinking agent, it is widely used in chemical synthesis, food processing, military industry, medicine, etc. Many fields. Since hydrogen peroxide decomposes to generate water and oxygen, it has no secondary pollution to the environment and is known as the "cleanest" chemical, so the application of hydrogen peroxide has a wider market. Nowadays, existing methods for preparing hydrogen peroxide include: barium peroxide and acid reaction, electrolytic sulfuric acid method, anthraquinone derivative autooxidation method (herei...
