Recently, the YS-9010 silver catalyst developed by SINOPEC Beijing Research Institute of Chemical Industry and produced by Sinopec Catalyst Co., Ltd. has achieved industrial application in the ethylene oxide/ethylene glycol plant of SINOPEC Yangzi Petrochemical Company. Since the application, the top-grade product rate of ethylene oxide and ethylene glycol has maintained at 100%, and the material consumption has reduced significantly.
SINOPEC Yangzi Petrochemical Company works with SINOPEC Beijing Research Institute of Chemical Industry and Sinopec Catalyst Co., Ltd. to carry out the industrial application of YS-9010 silver catalyst, which shows a maximum selectivity of 90% and an average selectivity of not lower than 80%. After the 500-hour catalyst taming process, the catalyst has achieved the goal of taming. Up to now, the catalyst is characteristic with low reaction temperature, good activity and less side reaction. The application of YS-9010 silver catalyst can improve the product quality, reduce the costs and improve the benefits.
