摘要: 通过对吉林舒兰煤矿褐煤进行人工煤化模拟实验, 探讨了煤化作用中不同温阶产物组分特征、气态产物甲烷碳同位素特征及煤成油和排油情况。指出温度是引起产物变化的主要原因, 煤化作用中生成的气态产物主要是非烃、饱和烃和烯烃, 低温阶段以非烃为主,甲烷含量随温度增加而增加, 重烃气在400~ 450 ℃达最大值;模拟气甲烷碳同位素随温度升高逐渐变重;煤不但可以生油而且可以排油, 排油过程在350 ℃之前就开始了, 在375 ~425 ℃排油量达最大值。

Abstract: Simulation experiment with coalification of lignite in Shulan coal mine, Jilin province was made to examine the component characteristics of product at different temperature stage, carbon isotope characteristics of methane in gaseous products, and coal-formed oil and its expulsion during coalification.It is suggested the temperature is the key control on change in products.The following conclusions can be reached :① nonhydrocarbon, saturated hydrocarbon and olefinic hydrocarbon are main gaseous products from coalification.Nonhydrocarbon is dominant in low-temperature stage, the content of methane increase with temperature, and heavier hydrocarbon gas peaks at 400 ~ 450 ℃.② carbon isotope of methane in gaseous products from coalification becomes heavier with temperature.③coal can generate and expel oil.It has expelled oil before 350 ℃, and peaks at 375~ 425℃.
