Problems solved by technology

At present, the partially oxidized ternary copper powder catalyst is mainly made by chemical methods or in combination with physical methods: it is made of CuSO 4 ·5H 2 O is the raw material, which is obtained after spray drying, dehydration, reduction, and partial oxidation. This method is due to the use of CuSO 4 ·5H 2 O is the raw material, if the raw material is not well controlled, it will lead to the instability of the catalyst performance of the final product; in addition, the S content in the catalyst obtained by this method is relatively high, so it will cause harm to producers, users and the environment

Abstract

The invention discloses a catalyst produced through water atomization and a manufacturing method thereof. The catalyst is prepared by melting a cathode electrolytic copper plate serving as a primary raw material at high temperature, performing high water pressure spray atomization, precipitation, high-temperature drying oxidization, selection and ball milling oxidization on the copper plate. Besides the characteristics of multiple pores, and large specific surface area of a traditional elemental sheet copper powder catalyst, the catalyst also has the property of containing three element components, namely copper, cuprous oxide and copper oxide. Due to the characteristics of multiple pores, sheet shape and large specific surface area, absorption and contact area between the catalyst and silica powder are increased, more Si and Cu alloy and eta phase can be formed, and the reaction activity of a contact is improved. The disadvantages that the content of S in the three-element copper catalyst produced by a chemical method using CuSO4.5H2O as a raw material is relatively high and the S does harm to producers, users and environments are overcome. The catalyst is continuous in production way, good in controllability and stable in quality.

Description

Technical field [0001] The copper powder catalyst and the manufacturing method thereof involved in the present invention specifically relate to a novel copper powder catalyst and a manufacturing method used in the production of organic silicon monomer by a water atomization method. Background technique [0002] Silicone is widely used as an "industrial monosodium glutamate". Its downstream and processed products are widely used in chemical, light industry, textile, medical, construction, electronic and electrical fields, and with the increase in the variety and quantity of downstream products of silicone , Its application areas will also continue to expand and develop. [0003] Organosilicon monomers are the foundation of the organosilicon industry, and the production level of monomers directly reflects the level of development of the organosilicon industry. Silicone monomers are needed to prepare silicone oil, silicone resin, silicone rubber and other silicone products. Many kind...
