ABSTRACT:
Coal-aqueous mixture characterized by having high coal solids concentrations are provided. Selected polyalkyleneoxide nonionic surfactants are employed at low concentrations to disperse coal in an aqueous carrier medium to coal solids levels of 70% by weight, or higher. The selected polyalkyleneoxide nonionic surfactants are characterized by having a high molecular weight and a hydrophilic portion comprised of at least about 100 repeating units of ethylene oxide.
