摘要：

Dehydrogenation of ethane to ethylene in the presence of CO2 was investigated over gallium oxide supported on HSSZ-13 with different Si/Al ratios. These catalysts exhibited higher activity as well as higher selectivity in comparison to HZSM-5 supported ones. 34% ethane conversion with 86.9% selectivity to ethylene could be obtained. The enhanced catalytic performance of Ga2O3/HSSZ-13 can be attributed to unique pore geometry of SSZ-13 support. However, the stability is not as good as that of Ga2O3/HZSM-5, owing to easy coking in channel with smaller pore-opening size. (C) 2015 Elsevier B.V. All rights reserved.
