S. Wang et al., Lithium-chloride-promoted sulfated zirconia catalysts for the oxidative dehydrogenation of ethane, CATAL LETT, 59(2-4), 1999, pp. 173-178
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.
