Abstract

Abstract : N and Ru species in the Ru/N-AC catalyst can adsorb and activate EDC and acetylene, respectively, generating a synergistic effect. Abstract : A Ru-based catalyst (Ru/N-AC) was prepared using N-doped carbon as the support and the catalytic performance of the one-step synthesis reaction of vinyl chloride monomer (VCM) from acetylene and 1, 2-dichloroethane (EDC) was assessed. It is indicated that 1% Ru/N-AC exhibited good catalytic activity with an initial acetylene conversion of 95.2% at 250 °C, an EDC total liquid hourly space velocity (LHSV) of 0.2 h −1 and a molar ratio n (EDC)/ n (C2 H2 ) of 1, much better than that of 1% Ru/AC or N-AC. Through BET, TG, XPS, ICP, TPR, TPD, TEM and XRD characterization, it is indicated that N-doped AC support can increase the amount of RuO2 and RuO x species in the catalyst and enhance its adsorption ability for both EDC and acetylene, suggesting that the N dopant and Ru species generated a synergistic effect in the one-step synthesis reaction of VCM.
