ABSTRACT:
A method of preventing the generation of dust or agglomeration of particulate material comprising coal by applying to the particulate material a mixture of from about 45 to about 90 weight percent of glycerin, from about 5 to about 50 weight percent of water, about 0.5 to about 3 weight percent of fatty acids and esters thereof and from 2 to about 15 weight percent of water soluble salts, which has been diluted with about 10–400 weight percent of water. The diluted compositIon is applied in an affective amount to suppress agglomeration of particulate material and its adhesion to surfaces and to substantially prevent the generation of dust. The concentrated composition has a freezing point of at least −35° C.
