Abstract

Abstract

The activated carbon supported copper-based catalyst was prepared by deposition-precipitation method and used to catalyze the direct vapor-phase oxycarbonylation of methanol to dimethyl carbonate (DMC). The effect of preparation conditions(such as copper salt, reductant, precipitant and loading amount ect) on the catalytic performance were investigated by XRD, H₂-TPR and SEM techniques. The result showed that under the condition of MeOH/CO/O₂(volume ratio)=5:11:1, SV=6 625 h^-1, Cu₂O /AC catalyst (Cu(CH₃COO)₂·H₂O as precursor, glucose as reductant, Cu₂O loading amount of 17.1%) showed satisfactory catalytic performance for DMC synthesis. The STY reached 99.36 mg/(g·h) and the selectivity of DMC was about 83.13%.
