| 摘 要： | 基于ChemCAD仿真软件，采用Gibbs最小自由能方法作为气化反应模型，建立了Shell粉煤加压气流床气化仿真模型。针对氧煤比、蒸汽煤比和气化压力3个主要工艺参数，安排了3因子3水平的全析因仿真实验，分析了各工艺参数对气化性能的影响。结果表明：氧煤比是影响产气率和粗煤气有效成分的重要因素，同时对消耗指标的亦有显著影响。产气率等效益指标随氧煤比的增加而增加，而消耗指标则随氧煤比的增加而减少；蒸汽煤比可以提高产气率，但主要影响H 2的含量，各消耗指标会随着蒸汽煤比的增加而减少；压力对煤气化性能指标影响不显著。进而，采用综合平衡优化方法，对煤气化工艺参数进行了综合优化，以协调各指标间可能的冲突，寻找到一组使各指标尽可能最优工艺参数的组合。
