Abstract

PURPOSE:To obtain a low-cost carbonaceous solid-water slurry having excellent flowability and stability, by using as main components a powdery carbonaceous solid, a dispersant for coal-water slurries composed of a particular water-soluble copolymer, a stabilizer and water. CONSTITUTION:The slurry compsn. comprises a powdery carbonaceous solid (a), such as coal, oil coke or petroleum pitch, a dispersant (b) for coal-water slurries composed of a water soluble copolymer prepared using as essential components a polyalkylene glycol monoacrylate monomer (I) of formula I and a sulfoalkyl methacrylate monomer (II) of formula II, a stabilizer (c), selected from clay minerals, polysaccharides, polyacrylic acid and salts thereof, and water (d). In the formulae, X is a C2-4 alkylene etc.; n is 1-100: Y is H, a C1-30 alkyl, etc. ; Z is a C1-4 alkylene; and M is H, an alkali (alkaline earth) metal, an ammonium group, or an amine base group.
