摘要

Abstract

This work presents the influence of dispersants on coal-water slurry (CWS)

which was prepared from the solid residue of plasma pyrolysis of coal. The effects of dispersant type

solid concentration

dispersant content

and temperature on the rheological properties of CWS are examined. A suitable empirical model regarding the relation between viscosity and temperature is proposed. Through the sedimentation experiment of CWS

dispersants are found to significantly promote the stability of CWS.
