Abstract
Stability of coal-water suspension (WCS) is one of the main criteria for obtaining fuel efficient. In the present work we investigated the sedimentation stability of coal-water suspension of 35% (in the presence and absence of hexane) stabilized by sodium dodecyl sulfate. Found that pretreatment of coal hexane (before being crushed) and further stabilization of coal-water suspension of 35% sodium dodecyl sulfate at concentrations of 0.8-.1.0% helps to ensure a stable dispersion system.
