【摘要】 本文对12种不同变质程度煤进行了吡啶和氯仿的索氏抽提,研究了溶剂抽提物的粘结性和溶剂抽提不溶物的吸附能力。结果表明,吡啶抽提物有较强的粘结性,吡啶不溶物有较大的吸附能力。综合利用吡啶可溶物和吡啶不溶物使得此法在经济上可行。更多还原

【Abstract】 This paper described trials on the extraction of pyridine and chloroform out of coals of 12 different ranks and studies on the cohesiveness of the solvent solubles and the absorption ability of the sol vent inolubtes, Test results indicate that the pyridine solubles have higher cohesiveness while the pyridine insolubles show greater absorption ability, therefore a combined usage of those two chemicals will make it economically possible to apply the prooess to production.更多还原
