Chromium oxide supported on SBA-15 was modified with Ce species by an incipient method. The effect of Ce on the activity of Cr/SBA-15 catalyst in the dehydrogenation of ethane with CO2 was investigated. The activity is enhanced for Ce modified Cr/SBA-15 catalyst for the dehydrogenation of ethane with CO2. The cycle between Cr(6+)supercript stop and Cr(3+)supercript stop species can be carried out viaing the dehydrogenation of ethane and oxidation of CO2 processes.
