%X For the conversion of hydrogen chloride to chlorine, a kind of catalyst containing 8% copper was prepared by impregnation method. Its 300 h life test was carried out in a quartz fixed-bed reactor at 400℃, 0.12 MPa, molar ratio of O2 to HCl 1, and HCl weight hourly space velocity (WHSV) 0.8 h-1. It was found that HCl conversion rate decreased from initial 70% to 50% after 300 h evaluation. The deactivation mechanism of catalyst was due to the sintering of CeO2 and loss of active components. The deactivated catalyst can be regenerated by chlorinating at low temperature and making up active components.
