Abstract:
1. A method of preventing the agglomeration of a particulate material and the adhesion thereof to surfaces upon exposure of the material to subfreezing temperatures comprising a) providing unagglomerated particulate material; b) providing a composition consisting of a glycerin-containing by-product formed from a manufacturing process for making fatty acid esters from at least one oil selected from the group consisting of vegetable oil and animal fats; and c) applying a dosage of about 200 to about 1400 g of glycerin per ton of particulate material of said composition to said unagglomerated particulate material wherein said dosage is an amount sufficient to suppress agglomeration of the particulate material and its adhesion to surfaces upon exposure of the particulate material to said subfreezing temperatures and wherein said dosage is substantially lower than the dosage required for deicing or anti-icing.
