摘　　要：基于CHEMKINâ模拟软件平台,以苯酚、甲苯、苯、甲基萘和二甲苯作为焦油的模型化合物,建立布朗气-生物质焦油气相化学反应动力学模型,通过数值模拟的方法研究通入布朗气情况下生物质焦油的解耦行为。研究结果表明:与常规焦油热解过程相比,布朗气有助于降低焦油热化学转化过程的起始温度,热裂解温度同比下降2.06%(747.05℃~619.35℃),能够促进焦油在气相中深度裂解,主要气相焦油成分分别下降1.8%(C_(6)H_(5)OH)、3.5%(C_(6)H_(5)CH_(3))、0.9%(C_(6)H_(6))、3.3%(C_(10)H_(7)CH_(3))、2.04%(C_(8)H_(10));产生的可燃气含量增加,同比增长6.9%(H_(2))、2.1%(CO)、4.1%(CH_(4))。Based on the CHEMKINâsoftware,phenol,toluene,benzene,methylnaphthalene and xylene were used as tar model compounds to establish a Brown-gas-biomass tar gas phase chemical reaction kinetics model in this paper,and the decoupling behavior of biomass tar was numerically investigated with the introduced Brown gas.The research results show that the Brown gas helps to reduce the onset temperature of tar thermochemical conversion process compared with the conventional tar pyrolysis process.The pyrolysis temperature decreases by 2.06%(747.05℃-619.35℃),which can promote the tar deep cracking in the gas phase,the main tar components decrease by 1.8%(C_(6)H_(5)OH),3.5%(C_(6)H_(5)CH_(3)),0.9%(C_(6)H_(6)),3.3%(C_(10)H_(7)CH_(3)),2.04%(C_(8)H_(10)),respectively.In addition,the content of combustible gas(H_(2),CO,CH_(4))increases by 6.9%,2.1%,4.1%,respectively.
