Catalytic Composites Based on Yttria Stabilized Zirconia for Oxidative Dehydrogenation of Ethane

摘要

LiCl/YSZ is found to be a very effective catalyst for the oxidative dehydrogenation of ethane. LiCl supported on YSZ-MgO composite shows increase in catalytic activity and ethylene selectivity. Addition of Mn and Sn as promoters to this system leads to 85% ethane conversion, 77% ethylene selectivity and 65% ethylene yield at 662℃. Use of Li_2O in the place of LiCl results in lower ethylene yields. Further modification is needed to improve the catalyst stability.
