摘要：

Ethanol steam reforming was studied over CuCoZnAl oxide with the addition of potassium. The catalyst was prepared by the coprecipitation method and characterized by X-ray diffraction, thermogravitnetry, Raman spectroscopy, temperature programmed reduction, BET specific surface area and SEM-EDAX. The influence of reaction temperature was examined between 400 and 600 degrees C with a H2O/C2H5OH molar ratio of 3.8. At 600 degrees C, the catalyst was very active with an ethanol conversion of 100%. The main products were CO2 and CO and minor amounts of CH4. The hydrogen yield was 5.2 mol of H-2 per mol of ethanol, which means a high hydrogen selectivity (87%). Stable activity and selectivity were obtained at 600 degrees C which could be attributed to the removing of carbonaceous deposits. (C) 2007 Elsevier B.V. All rights reserved.
