Investigation on binary copper-based catalysts used in the ethanol steam reforming process

摘要: The use of copper-based binary catalysts, Cu/Zr oxides and Cu/Al oxides, has been examined to produce hydrogen from ethanol in the steam reforming process. catalysts were compared with non-noble bicomponent consisting nickel cobalt: Ni/Zr Co/Zr, Ni/Al Co/Al, prepared tested identical way. Catalytic tests carried out fixed-bed reactor temperature range 433–873 K for initial molar ratio water equal 1:3. Ethanol conversion approached near 100%. Catalysts characterized by XRD, TPR. oxides. catalyst showed very good selectivity. It is significant that carbon monoxide appeared only above 600 K its selectivity not exceeded 3% higher range. No methane detected. Hydrogen yield was relatively stable 513 873 K. Similarly, presence neither CO nor CH4 found products. correlation between activity textural properties found.
