Abstract
Coal pitch water slurry is prepared by coal pitch powder, dispersants, and deionized water. Using two kinds of particle size distribution powder, influence of the amount of dispersants and slurry content on the slurry ability of coal pitch water slurry is studied. The results show that at the same amount of dispersants, the apparent viscosity of coal pitch water slurry increases with increasing the slurry content. On the whole, at the same amount of dispersants and slurry content, the apparent viscosity of coal pitch water slurry prepared by powder of gradation 2 is less than that of gradation 1.
