Oxidation of Hydrocarbons and Alcohols by Carbon Dioxide on Oxide Catalysts

Development of biogas reforming Ni-La-Al catalysts for fuel cells

“…The increase of reaction rate at the beginning of the experiment suggests a slow process where an equilibrium in La 2 O 2 CO 3 and for others carbonaceous species on the surface nickel crystallites is established. La 2 O 2 CO 3 phase has a moderate stability and can be partially decomposed at reaction temperatures [21,22]. This species can be considered as an oxygen dynamic tampon.…”

Effect of supports on catalytic activity of chromium oxide-based catalysts in the dehydrogenation of propane with CO2

“…These results concern mainly the dehydrogenation of ethane [1][2][3][4][5], propane [4,[6][7][8][9], butanes [4,9,10] and ethylbenzene [11][12][13][14][15] in the presence of CO 2 . The generally accepted role of carbon dioxide in the dehydrogenation of hydrocarbons is removal of hydrogen and suppression of coke deposition on the catalyst surface.…”

CO2 utilization for the formation of styrene from ethylbenzene over zirconia-supported iron oxide catalysts

“…2,3 It has been recently reported that carbon dioxide can be utilized as an oxidant for the oxidative conversions of alkanes, alkenes, and alcohols 4 and that oxygen generated during CO 2 reduction can participate in both partial oxidation and dehydrogenation. 4,5 Catalytic dehydrogenation of ethylbenzene (EB) is important in the manufacture of a styrene monomer (SM), which needs a large excess amount of superheated steam for preventing catalyst deactivation due to coke formation as well as enhancing catalytic activity. We have previously reported that CO 2 could also play a role in the EB dehydrogenation over supported iron oxide catalysts as an oxidant with improved coke stability.…”
