以五彩湾煤镜质组、惰质组为研究对象,建立两种不同的体系,镜质组与惰质组无相互作用体系( A)和相互作用体系( B)。利用热重技术( TG)和傅里叶变换红外技术( FT-IR),将两体系的热解固体产物进行红外分析。结果表明,在300~450℃,体系B的脂肪氢含量高于体系A,表明镜质组与惰质组之间发生了烷基自由基转移反应,芳氢的含量也是体系B多于体系A,这说明镜质组与惰质组之间同时发生了芳构化作用,随温度升高,镜质组生成少量氢自由基与惰质组发生侧链取代反应；在500~700℃,体系B的脂肪氢含量和芳氢含量均低于体系A,表明此时镜质组与惰质组之间发生缩聚反应及缩合反应；750~800℃时,脂肪氢和芳香氢含量均为体系B大于体系A,说明体系B中,镜质组产生较多的氢自由基与惰质组大分子芳香结构发生氢化反应,同时与惰质组发生侧链取代反应；850~900℃时,镜质组与惰质组之间进一步发生多环芳香缩合反应。

Two different systems for vitrinite and inertinite from Wucaiwan coal were established:no interaction ( A) and interaction system ( B) . Thermogravimetric ( TG) and fouriertransform infrared ( FT-IR) were used to analyze the pyrolysis products in the two systems. The results show that at 300~450℃ the hydrogen content of B is higher than that of system A, indicating that the reaction of alkyl radical transfer between the vitrinite and inertinite. Meanwhile, the aromatic hydrogen of system B is more than that of system A, which shows that aromatization between vitrinite and inertinite occurs, and a few hydrogen free radicals produced from vitrinite occur macromolecular aromatic structure side chain substitution reaction with inertinite. From 500 to 700℃, the aliphatic and aromatic hydrogen content of system B is lower than that of system A, showing that polycondensation reaction and condensation reaction exist between the vitrinite and inertinite. From 750 to 800℃, aromatic aliphatic hydrogen content of system B is greater than that of system A, which means that vitrinite generates more hydrogen free radicals and occur hydrogenation reaction with inertinite macromolecular aromatic structure as well as side chain substitution reaction with inertinite in system B; From 850 to 900 ℃, polycyclic aromatic condensation reaction proceeds further between vitrinite and inertinite.
