摘要
以榆林长焰煤为原料,考察了含氮、氧或硫的极性溶剂对该煤种的抽提效果。通过一系列对比实验确定环己酮作为溶剂,并考察了热溶胀温度对抽提率的影响。
The experiment was conducted on the long-burning coal of Yulin as raw material,and the extraction effect of the polar solvent containing nitrogen,oxygen or sulfur on the coal was investigated.Through a series of comparative experiments,cyclohexanone was determined as a solvent,and the influence of factors such as thermal swelling temperature on the extraction rate was investigated.
