摘要
文中研究了三种不同种类煤的镜质组、丝质组及其焦炭的性质,结果表明,显微组分间有着明显的性质差异,不同煤化程度镜质组的H/C比、挥发分产率、含氧官能团的脂肪氢和粘结性等明显大于丝质组。三种丝质组都不膨胀,其收缩度均小于镜质组。以显微组分的焦炭性质区分,丝质组的比表面积均大于镜质组,脱灰后的焦炭,其总孔容积增大,比表面积减小。
The properties of vitrinite and fusinite of three different ranks of coals and the coke characteristic are studied in this paper.The results show that the properties between their macerals are obviously different,the H/C ratio,volatile matter yield,oxygen-containing functional groups,aliphatic hydrogen and caking property of vitrinite of various ranks of coals are apparently higher than that of fusinite,three types of fusinite are non-swelling, their contraction are smaller than that of vitrinite.The specific surface area of coke fusinite of maeeral is greater than that of vitrinite.The total pore volume of the deashed coke is increased, and its specific surface area reduced.
