摘要: The swelling ratio of Wandoan coal is related to the amount total huminite as well fluorescing huminite. highest observed in 1.25-1.30 density fraction, which also has content Illinois No. 6 contains less and more nonfluorescing vitrinite compared with shows only a general increase its increasing content. does not swell properly result poor solvent penetration due presence porous, telocollinite. dissolves at 300°C because increased vesiculation results an external internal dissolution relative swelling. study that coals maceral composition, turn, reflection environment formation.
