Preparation and Characterization of Nitrogen Modified Mesoporous Carbons and Its Catalytic Activity for Acetylene Hydrochlorination Reaction

A series of nitrogen modified mesoporous carbons and Au/MOMC catalysts were prepared by triconstituent co-assembly and characterized by BET and EA methods.The catalytic performance of mesoporous carbons and Au/MOMC catalysts for acetylene hydrochlorination to vinyl chloride in a packed bed reactor and the optimal preparation conditions was studied.Under the reaction conditions of temperature 180 ℃,C2H2 hourly space velocity(GHSV) 180 h-1,feed volume ratio V(HCl)/V(C2H2) = 1.15 and Au loading of 1(wt)%,the acetylene conversion of Au/MOMC were 89%(higher than Au/MOMC by 34%),and vinyl chloride monomer selectivity was approximately 99.99%.
