PITCH-CONTAINING COMPOSITION Abstract of the Disclosure A composition in the form of a dispersion or a slurry, which comprises an aqueous medium, a finely divided pitch, and a specific dispersant of an amount sufficient for maintaining the pitch in the dispersed state. The dispersant is selected from (A) a compound of the formula shown below, (B) a polymeric material obtained by crosslinking the compound (A) with a crosslinking agent, (C) a salt of the sulfuric ester of the compound (A) and (D) a salt of the sulfuric ester of the polymeric material (B). The compound (A) is expressed as follows: Z - (Y - X)p wherein Z is an organic radical capable of forming, together with p number of hydrogen atom, an active hydrogen-containing organic compound of the formula Z - (H)p where H is the active hydrogen and p is a positive integer; Y is a polyoxyalkylene group consisting essentially of a plurality of monomer units, the monomer unit being at least one member selected from an ethylene oxide monomer unit (-CH2-CH2-O-) and a propylene oxide monomer unit (-CH2-CHCH3-O-); X is a hydrogen atom; and p has the same meaning as above. The composition is suitable as a fuel. - 1 -
