摘　　要：建立了数学模型,把含水乙醇等离子体重整制氢体系中的主要化学反应,归结为各物种浓度的常微分方程组的初值问题来求解,计算方法选用Ode113法,在假定的几种不同乙醇裂解关键路径下分别得到了几种主要产物随停留时间的变化规律,并将模拟结果与前期实验结果进行了对比。结果表明:乙醇等离子体重整制氢中乙醇分子4种化学键的断裂具有同等机会。A mathematical model is established by the main chemistry reaction in the hydrogen production from ethanol by plasma reforming as the initial problem of ordinary differential equation for different species. The main gaseous production reaction time is calculated by different pathwayes of ethanol cracking with the Matlab of Ode113. The key reaction way is obtained compared experimental results with simulation results. The result shows that the four bands in ethanol have the same opportunity in cracking during the reaction of ethanol plasma reforming.
