【摘要】 离子液体作为一种新型的工业溶剂,尚未应用到煤化工领域.以离子液体——[Emim]BF4作为煤直接液化的溶剂,选用神华煤样和胜利煤样,在常压低温条件下,测定离子液体-煤浆体黏度,为离子液体中煤的液化作基础研究.结果表明,煤油比越小,煤浆体系初始黏度越低,且黏度随温度的升高而降低;在50℃～65℃之间煤浆黏度受溶胀的影响,发生明显的变化.更多还原

【Abstract】 Ionic liquid is a new kind of solvent,but it has not been applied to coal chemical industry.Ionic liquid was firstly used as coal-direct liquefaction solvent in this paper.Viscosity of Shenhua coal slurry and Shengli coal slurry was measured at atmospheric pressure.The results show that viscosity is lower with more solvent and temperature has an influence to it.When temperature increases,viscosity of coal slurry declined.Because of swelling viscosity has a special situation between 50 ℃ and 65 ℃.更多还原
