| titleOfInvention | Viscosity depressant for concentrated aqueous slurry of coal |
| abstract | PURPOSE: To reduce the viscosity of a coal/water slurry and improve its fluidity and stability, by adding a co-condensate of ligninsulfonic acid and naphalenesulfonic acid with formalin and a polyphosphoric acid. n CONSTITUTION: The viscosity depressant contains (a) a co-condensate of ligninsulfonic acid and (alkyl)naphthalenesulfonic acid with formalin or salt thereof and (b) polyphosphoric acid. The ligninsulfonic acid and (alkyl)naphthalenesulfonic acid used in a ratio of 1:9W9:1 by weight. The salts are alkali metal salt, alkaline earth metal salt, ammonium salt, amine salt, etc. The co-condensate has an average degree of condensation of 1.5W20, pref. 2W10. n COPYRIGHT: (C)1985,JPO&Japio |
