Carburized Cesium-doped Ni/ZrO<sub>2</sub> for Efficient Hydrogen Production and Less Carbon Deposition during Ethanol Steam Reforming

Abstract

Carburized Cs0.2Ni0.8/ZrO2 catalyst is useful for the steam reforming of ethanol (ethanol : water =1:13) at 773 K to produce hydrogen at 1.95 mmol/min/g-cat during 60 h, with 82 % CO2 selectivity with trace amounts of CO and CH4. The cesium addition to the Ni/ZrO2 catalyst resisted the carbon deposition, kept more reducing Ni carbide and produced highly hydrogen.
