Abstract
The oxidative dehydrogenation of ethane over sulfated-zirconia-supported li thium chloride catalysts has been systematically investigated. The optimal experimental parameters were obtained. It is found that sulfation of zircon ia increases the catalytic activity. 2-3.5 wt% lithium chloride on sulfated zirconia catalysts exhibit high catalytic activity for oxidative dehydroge nation of ethane, with particularly high activity for ethene production. 70 % selectivity to ethene at 98% ethane conversion, giving 68% ethene yield, is achieved over 3.5 wt% LiCl/SZ at 650(degrees)C.
