Carbon-supported copper-organic framework as active catalysts for acetylene hydrochlorination

In this work, activated carbon supported Cu-MOF as an acetylene hydrochlorination catalyst for manufacture vinyl chloride. Cu-MOF/AC with 15 wt% Cu-MOF content behaves the initial acetylene conversion of 99.2% and vinyl chloride selectivity of 98.5% at 200C. By combing steady-state experiments and physical-chemical characterization results (XPS, BET, H2-TPR, C2H2-TPD, XRD and HCl adsorption experiments), Cu-O-C is shown to retard the reduction of Cu2+, improve the reactants adsorption and strengthen the anti-coking ability of Cu-based catalysts. According to the previous studies and the Rideal-Eley mechanism, it is proposed that Cu2+ first adsorbed C2H2 to generate transition states in catalysis acetylene hydrochlorination.The accepted manuscript in pdf format is listed with the files at the bottom of this page.
