煤直接液化升温阶段气体产物组成关联模型

Correlation Models of Gas Products in Heating-Up Stage of Coal Direct Liquefaction

为了预测煤直接液化升温阶段气体内部不同产物组分分布情况,通过回归分析大量实验数据,对煤直接液化反应的气体集总内不同气体分子组成分布进行了关联性研究,建立了煤直接液化升温阶段气体产物组成与反应条件、液化反应产物集总组分分布的预测关联模型。利用SPSS软件回归得到了相应模型参数,并对关联模型进行了拟合优度检验。结果表明,拟合的CH4,C2H6,C3H8,C4,CO,CO2和H2S组分与实验值相对偏差分别为1.1%,1.0%,6.0%,9.8%,9.3%,0.5%和0.4%,说明拟合效果较好。

To predict distributions of different gas component in heating-up stage of coal direct liquefaction, regression analysis on a great deal of experimental data of coal direct liquefaction under different reaction temperature and different residence time was carried out. Correlation models were developed to study the correlate between gas component and reaction conditions, lumped product components. The corresponding regression model parameters were obtained, and the correlation models were optimized by SPSS software. The relative error between experiment and simulation of CH4, C2H6, C3H8, C4, CO, CO2 and H2S were 1.1%, 1.0%, 6.0%, 9.8%, 9.3%, 0.5% and 0.4%, respectively, which indicated that the simulated results agreed with the experimental results.
