摘要： Molten pitch, such as obtained in petroleum refining, is comminuted as such in the presence of water to obtain coarse pitch particles solidified during the comminution by contact with the water. The coarse pitch particles are further pulverized in the presence of water and, preferably, a dispersant to form a slurry containing the finely pulverized pitch particles dispersed in the water.

摘要： 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).sub.pwherein 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).sub.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 (--CH.sub.2 --CH.sub.2 --O--) and a propylene oxide monomer unit (--CH.sub.2 --CHCH.sub.3 --O--); X is a hydrogen atom; and p has the same meaning as above. The composition is suitable as a fuel.
