| 摘 要： | 对不同反应条件下乙醇水蒸气重整反应系统平衡的物质分布进行了热力学计算。结果表明:低压有利于乙醇水蒸气重整主反应的进行;在n(水)∶n(乙醇)=8∶1条件下,温度越高乙醇的转化率越高,氢的含量也越高;在900 K时,水醇比越高越有利于乙醇水蒸气重整反应向正方向进行。实验结果与热力学计算的产物分布曲线基本一致,进一步证明了热力学计算的正确性。

| Abstract: | The equilibrium substance composition of ethanol steam reforming system was calculated by thermodynamics and compared with measured ones.Effects of temperature,pressure and water/ethanol molar ratio were also analyzed with thermodynamics theroy.The results show that the decrease of pre-(ssure) favore the steam reforming of ethanol in this system.The conversion of ethanol and the content of(hydrogen) increase with the increasing of reaction temperature,when water/ethanol molar ratio is equal(to 8 at) 101.325 kPa.At 900 K the higher water/ethanol molar ratio the desired reaction of ethanol steam(reforming) become predominant one.The calculated trendlines of composition are in accordance with the(experiment) ones,which further proved the correctness of the thermodynamic analysis. |
