低阶煤亚显微组分与煤比表面积之间的关系

摘要

显微组分与比表面积是决定煤特性的重要指标，然而两者对煤各种特性的影响又互有重叠。为明确煤显微组分尤其是亚显微组分与比表面积间关系，通过实验发现，均质镜质体、粗粒体和微粒体对煤比表面积起决定作用，基质镜质体、微粒体对比表面积起微调作用。%Maceral and specific surface area are the important indexes of the coal properties.However,they influence over various properties of coal,and is overlapped.In order to find the relationship of low rank coal macerals and specific surface area,this paper has done many experiments and found that homogeneous vitrinite, coarse particles and microsomal decide the coal specific surface area,matrix vitrinite,microsomal contrast trimming effect on surface area.
