Abstract. Steam reforming, partial oxidation, and oxidative steam reforming of ethanol over Ir/CeO2 catalysts were studied to elucidate the reaction pathway and determine catalytic stability. Temperature-programmed desorption and surface reaction revealed that ethoxy species were immediately formed on ethanol adsorption at room temperature, and were mainly further oxidized to acetate and ca…
Abstract. Steam reforming of ethanol over unsupported Ni and Ni–Cu catalysts was investigated. Ethanol and the reaction intermediates like acetaldehyde and acetone are entirely converted into hydrogen and C1 products at 400 oC, while methane steam reforming and reversible water gas shift are the major reactions at higher temperatures. The Ni–Cu catalyst exhibited stable performance duri…
