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
