摘要
基于吉布斯自由能最小化原理,对乙醇水蒸气重整制氢进行模拟,分析温度、压力及水醇比对重整反应的影响。在温度为100~1 000℃、压力为0.1~9.0 MPa、水醇比为1~10的条件下,研究H_(2)、CH_(4)、CO_(2)、CO的平衡物质的量。结果表明,在研究选取的条件下,根据H2产量以及经济效益和能源效率,得到反应的最佳工况为温度为700℃、压力为常压、水醇比为7。
Based on the principle of minimizing Gibbs free energy,the simulation of hydrogen production through ethanol steam reforming is conducted,and the influences of temperature,pressure and the water-alcohol ratio on the reforming reaction are analyzed.The equilibrium amounts of H_(2),CH_(4),CO_(2) and CO are studied under the conditions of temperature ranging from 100 to 1000℃,pressure ranging from 0.1 to 9.0 MPa and water-alcohol ratio ranging from 1 to 10.The results show that under the conditions selected in the study,based on the H2 production,economic benefits and energy efficiency,the optimal working conditions of the reaction are obtained as a temperature of 700℃,a pressure of atmospheric pressure and a water-alcohol ratio of 7.
