摘　　要：根据重油结构成分,选取甲苯代表芳香烃化合物,正庚烷代表烷烃类化合物,丙烯代表烯烃类化合物,构建重油替代物机理模型。采用Chemkin软件使用DRG方法对其简化,同时进行敏感性分析,得到简化机理。对简化机理进行滞燃期与层流火焰速度的验证,验证简化机理的合理性。将其耦合得到121组分、700个基元反应的重油替代物简化机理。ccording to the structure and composition of heavy oil,the mechanism model of heavy oil substitutes was constructed by choosing toluene as the aromatic compound,n-heptane as the alkane compound and propylene as the olefin compound.Chemkin software was used to simplify it by DRG method,and sensitivity analysis was carried out to obtain the simplified mechanism.The ignition delay and laminar flame speed of the simplified mechanism are verified to verify the rationality of the simplified mechanism.A simplified mechanism of heavy oil substitutes with 121 components and 700 elementary reactions was obtained by coupling them.
