FLOWING-AID COMPOSITIONS FOR THE SYNERGISTIC ENHANCEMENT OF THE FLOWABILITY OF STABLE AQUEOUS COAL SUSPENSIONS

摘要

A composition for increasing the flowability of coal slurries having more than 60% coal solids content and a method for its use. The composition comprises at least one viscosity regulator, at least one maleic acid/acrylic acid copolymer of a specific viscosity range, and optionally, at least one polysaccharide.
