摘要
In this work, activated carbon supported Cu-MOF was used as an acetylene hydrochlorination catalyst to manufacture vinyl chloride. Cu-MOF/AC with 15 wt. % Cu-MOF content has the initial acetylene conversion of 99.2% and vinyl chloride selectivity of 98.5% at 200 °C. By combining steady-state experiments and physical–chemical characterization results (XPS, BET, H 2 -TPR, C 2 H 2 -TPD, XRD, and HCl adsorption experiments), Cu–O–C is shown to slow the reduction of Cu 2+ , improve the reactants adsorption, and strengthen the anti-coking ability of Cu-based catalysts. According to the previous studies and the Eley–Rideal mechanism, it is proposed that Cu 2+ first adsorbed C 2 H 2 to generate transition states in acetylene hydrochlorination catalysis.
