摘要：

V-containing catalysts supported on Al2O3, modified with varying amounts of ZrO2, were prepared by impregnation method. Dehydrogenation of ethylbenzene with CO2 was run over these catalysts in a fixed-bed downflow stainless steel reactor. Compared with pure Al2O3 support, a small amount of ZrO2 in the support led to a significant increase in catalytic activity. Partial reduction of vanadium oxides and carbon deposition were the main reasons for the decreased catalytic activity. (C) 2013 Elsevier B.V. All rights reserved.
