The global Minamata Convention on Mercury came into effect in 2017 exerting huge environmental pressure on acetylene-based polyvinyl chloride (PVC) processes. Research and development of mercury-free catalytic synthesis technologies for the entire PVC industry and even the sustainable development of the chlor-alkali industry are of great significance. Here, we report the catalyzed coupling reaction of acetylene and ethylene dichloride to synthesize vinyl chloride over a mercury-free, nitrogen-doped activated carbon catalyst (N@AC). The catalyst delivered stable performance with an ethylene dichloride conversion over 95%, acetylene conversion at similar to 90%, and selectivity for vinyl chloride over 98% at 260 degrees C. Both X-ray photoelectron spectroscopy data and catalytic activity of the catalysts revealed pyridinic N to be the active site. The results of this study show that the catalytic coupling reaction of acetylene and ethylene dichloride to synthesize vinyl chloride over a N@AC catalyst has a very attractive prospect in the PVC industry.
