Abstract

PURPOSE:To provide the title stabilizer which enables formation of a slurry having low viscosity and excellent sedimentation stability and free from an increase in the viscosity with time even when the concn. of a solid fuel is high, and which comprises as indispensable ingredients a surfactant and an antioxidant. CONSTITUTION:A dispersion stabilizer for a solid fuel-water slurry comprises a surfactant and an antioxidant as indispensable ingredients. Examples of the surfactant include anionic surfactants, such as a salt of a formaldehyde condensate of naphthalenesulfonic acid and a salt of a product prepd. by hydrolyzing an alpha-olefin-maleic anhydride copolymer, or nonionic surfactants such as polyoxyalkylene alkyl ether. Preferred examples of the antioxidant include hydroquinone, cresol, phenyl-2-naphthylamine. Examples of the solid fuel include coal, deashed coal, coal carbonization coke, and petroleum coke.
