摘要：

In the present work, tin-sulfur based catalysts were prepared using Na2SO3 and (CH3SO3)(2)Sn and were tested in acetylene hydrochlorination. Based on the analysis of experiments results, the acetylene conversion of (CH3SO3)(2)Sn/S@AC is still over 90% after a 50 h reaction, at the reaction conditions of T = 200 degrees C, C-HCl:V-C2H2 and C2H2-GSHV = 15 h(-1). According to the results of X-ray photoelectron spectroscopy (XPS), IFICI adsorption experiments, and acetylene temperature programmed desorption (C2H2-TPD), it is reasonable to conclude that the interaction between Sn and S not only can retard the oxidation of Sn2+ in catalysts but also strengthen the reactant adsorption capacity of tin-based catalysts. Furthermore, results obtained from nitrogen adsorption/desorption and XPS proved that the CH3SO3-can effectively decrease the coke deposition of (CH3SO3)(2)Sn/AC and thus prolong the lifetime of (CH3SO3)(2)Sn/AC.
