摘要

摘要: 本研究探讨利用ZnCl₂分离液分离显微组分时不同的ZnCl₂分离液之比重对热解参数T_max的影响,实验上利用单一煤样(台湾裕峰煤)配制几个不同比重的ZnCl₂分离液,将煤样浸泡其中再各分成两部分,一部分直接晾干,另一部分清洗煤样中的ZnCl₂分离液后再行晾干。最后将所有样品进行热解分析。结果显示,T_max值随着ZnCl₂分离液比重的增加而有提前到达的趋势,而在洗除含有不同比重ZnCl₂分离液的煤样,可恢复此样品应的的T_max值。这说明ZnCl₂分离液比重的增加有加强催化的效果,同时亦显示热解参数T_max值的稳定性。

Abstract: The influence of density of ZnCl₂ separation liquid, used for maceral separation, to T_max of Rock Eval pyrolysis was studied in this research. High volatile bituminous coal samples were collected from Yufeng Mine in Sanhsia, North Taiwan. The coal samples were crushed and then immersed in ZnCl₂ solution with five different density of 1.12-1.28g/cm³. Half of the immersed samples were dried after thorough water washing, another half of the immersed samples were dried without washing. All of the samples were run by Rock Eval pyrolysis afterwards. The results indicate that T_max decreases with increasing density of ZnCl₂ solution for unwashed samples. On the other hand, T_max is rather stable for wased samples. It seems ZnCl₂ solution has somekind of catalytic effect on T_max, although T_max is still the most stable parameter in pyrolysis.
