CO gas phase coupling oxalic acid as a multi-step reaction system. Based on the selection of the best catalyst and the theoretical study, the engineering problems of coupling CO gas phase to diethyl oxalate were studied by means of simulation calculation, catalyst engineering research and mode operation, and the coupling reaction and regeneration reaction rate Matching the key technologies. Based on the reaction kinetics and the sensitivity analysis of reaction parameters, the rate of non-linear multistep cycle of complex reaction was solved and the zero-emission clean process was solved by continuous operation of 10 000 hours of mold test. The developed catalyst For CO coupling reaction of industrial amplification project, for industrial production provides a green chemical route
