摘　　要：2-丁烯是石油裂解的产物之一,也是大分子组分燃料燃烧的中间产物,在化工及燃烧领域起着至关重要的作用。以点火延迟时间和重要组分为简化目标,交叉使用直接关系图法(directed relation graph method,DRG)类算法对其详细机理进行简化,得到了包含71种组分和430步基元反应的简化机理。以层流火焰速度、组分摩尔分数等参数为基础,对简化机理进行了误差分析,并通过对比点火延迟实验数据,发现简化机理和实际有很好的吻合,验证了简化机理的有效性。最后结合敏感度分析,得到了2-丁烯的基本反应路径。As one of the products of petroleum cracking and the intermediate producttof macromolecular fuel combustion,2-butene plays an important role in chemical industryand combustion field.The detailed mechanism of the ignition delay time and important groupwas simplified by cross-use of DRG(Directed relation graph)algorithm,and the simplified mechanism containing 71 components and 430 steps was obtained.Based on laminar flame velocity,component concentration and other parameters,the error analysis of the simplified mechanism was carried out.By comparing the experimental data of ignition delay,it was found that the simplified mechanism was in good agreement with the actual one,and the effectiveness of the simplified mechanism was verified.Finally,the basic reaction path of 2-butene was obtained by sensitivity analysis.
