Thermodynamic analysis of steam reforming of ethanol for hydrogen generation

摘要: Thermodynamic equilibrium of ethanol steam reforming has been studied by Gibbs free energy minimization method for hydrogen production in the ranges water-to-ethanol ratio from 0 to 20, reaction temperature 400 2000 K, pressure 1 60 atm, argon-to-ethanol 100. The optimal conditions suitable use molten carbonate fuel cell and solid oxide were obtained as follows: 900–1200 K, 3:6, 1 atm. Under conditions, complete conversion ethanol, 60.52–83.58% yield 32.82–79.60% carbon monoxide could be no coke forms. Higher pressures have a negative effect, but inert gases positive on yield. Coke tends form at lower temperatures ratios. Copyright © 2008 John Wiley & Sons, Ltd.
