Tin-sulfur based catalysts for acetylene hydrochlorination
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 = 200oC, VHCl/VC2H2 = 1.1:1.0 and C2H2-GSHV = 15 h–1. According to the results of X-ray photoelectron spectroscopy (XPS), HCl adsorption experiments, and acetylene temperature programmed desorptio
