Ru/N-AC catalyst to produce vinyl chloride from acetylene and 1,2-dichloroethane

Author affiliations

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(C2H2) 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 RuOx 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.
