| Abstract: | According to the high production of coal pitch and the low efficient utilization rate in China,with the proper dispersant added,the coal pitch powder from the freezing coal pitch grounding could prepare the coal pitch water slurry with a similar properties of the coal water slurry.In combination with the research results of the coal water slurry,the dispersant function principle in the preparation of the coal pitch water slurry were analyzed.The research on the coal pitch water slurry and the influence factors in the preparation process were analyzed and summarized.Based on the circumstances,the research orientation of the coal pitch water slurry was further analyzed. |
