摘要
针对低温煤焦油利用中低温煤焦油脱水的难题,采取神木和大同低温热解煤焦油为研究对象,结合其含水特征,采用二步法进行脱水,以考察低温煤焦油的脱水效果。
According to difficult problem of low temperature coal tar dewatering, Shenmu and Datong low-temperature pyrolysis coal tar was studied, combined with water contained characteristics, the two-step dewatering test was conducted to investigate dewatering effect of low temperature coal tar.
