Abstract
The wet flow characteristic of water-insoluble solid particles such as coal is enhanced by forming on the surface of the solid particles a coating of a fluid having the property of lowering surface tension in aqueous solution, preferably a water solution of a substance from the group consisting of methyl and dimethyl naphthalene sulfonates and ethoxylated linear secondary alcohols, the substances being highly water soluble and the water solution having a low viscosity, a high flash point and low toxicity.
