Thermodynamic analysis of hydrogen production from steam reforming of ethanol
摘要
Abstract
A thermodynamic analysis of hydrogen production from ethanol steam reforming was carried out with a Gibbs free energy minimization method. The effects of temperature, pressure, H2O/EtOH and MeOH/EtOH on the equilibrium composition of the system were considered. A detailed calculation is presented on a range of reaction conditions, i.e., pressure of 1×105~80×105 Pa,temperature of 700~1 300 K,and H2O/EtOH and MeOH/EtOH feed ratios in 1:1~11:1 and 0:1~0.9:1, respectively. And the equilibrium moles of hydrogen, methane and carbon were examined. The conversion rate of ethanol reached 100% under the selected conditions. The equilibrium moles of hydrogen, methane and carbon were analyzed. The optimum operating conditions for the hydrogen production from ethanol steam reforming were suggested as 1×105Pa and 900 K, with H2O/EtOH in 11:1 and MeOH/EtOH in 0.9:1. Carbon deposition can be avoided by adjusting the reaction conditions.关键词
