Description

technical field [0001] The invention relates to a rapid preparation method of a resin-type carbon-supported copper catalyst, which belongs to the technical field of preparation and application of carbon-based composite materials. Background technique [0002] Carbon-supported copper catalysts are commonly used in the synthesis of dimethyl carbonate, with low toxicity and cheap raw materials. For example, CN102600843A and CN102872879A patents are based on activated carbon-supported copper catalysts in methanol gas-phase oxidative carbonylation to synthesize dimethyl carbonate; There are many disadvantages, the utilization rate of activated carbon is low, the efficiency is low, and the use is greatly limited. Some also use copper-based catalysts for methanol gas-phase oxidative carbonylation to synthesize dimethyl carbonate, but the activity is low and the selectivity is poor. There are still problems in use. Many disadvantages. [0003] Resin has a macromolecular pore struct...

[0002] Carbon-supported copper catalysts are commonly used in the synthesis of dimethyl carbonate, with low toxicity and cheap raw materials. For example, CN102600843A and CN102872879A patents are based on activated carbon-supported copper catalysts in methanol gas-phase oxidative carbonylation to synthesize dimethyl carbonate; There are many disadvantages, the utilization rate of activated carbon is low, the efficiency is low, and the use is greatly limited. Some also use copper-based catalysts for methanol gas-phase oxidative carbonylation to synthesize dimethyl carbonate, but the activity is low and the selectivity is poor. There are still problems in use. Many disadvantages

[0003] Resin has a macromolecular pore structure and is an ideal material for preparing activated carbon, such as CN103545520A patent, but this patent uses a large number of raw materials and complicated processes, and there are still many disadvantages; therefore, resin-type carbon-supported copper catalysts are still in the research stage
