Ternary copper catalyst alloy full fusion preparation process

Abstract

The invention discloses a ternary copper catalyst alloy full fusion preparation process. The ternary copper catalyst alloy full fusion preparation process comprises the following steps of mixing materials, specifically, mixing and stirring 40%-60% of fine copper powder and 40%-60% of oxygen-containing copper according to a certain proportion for about half an hour; high-temperature reaction, specifically, putting the mixed raw materials into a high-temperature diffusion furnace, enabling aerobic copper and copper powder to react at high temperature, under the anaerobic condition, filling nitrogen for whole-process protection, carrying out high-temperature reaction for four hours, controlling the center temperature to be about 7000 DEG C, and discharging to be blocky; and crushing, specifically, primarily crushing the blocky raw materials, and then crushing again. According to the ternary copper catalyst alloy full fusion preparation process, nitrogen is added for protection in the processes of secondary batching, ball mill alloying, raw material stabilization, screening and packaging, the processing fineness of the copper powder can be effectively reduced, meanwhile, the content proportion of cuprous oxide is increased, and the problem that the use effect is poor due to the fact that the processing fineness of the copper powder is large and the content proportion of the cuprous oxide is small is solved.

Description

technical field [0001] The invention belongs to the technical field of fusion preparation of ternary copper catalyst alloys, and in particular relates to a fully fusion preparation process of ternary copper catalyst alloys. Background technique [0002] Due to the wide application of ternary copper catalysts, the research on ternary copper catalysts in my country has been relatively active in recent years. The problem in the existing technology is that the main reasons for determining the effect of copper powder are the processing fineness of copper powder and cuprous oxide. Therefore, there is a need for a method that can reduce the processing fineness of copper powder and increase the content ratio of cuprous oxide to meet the needs of the market. Contents of the invention [0003] Aiming at the problems existing in the prior art, the present invention provides a fully fused preparation process for a ternary copper catalyst alloy that reduces the processing fineness of co...
