Filed: 1937-10-11
Abstract: 503,841. Composition fuel. STEVENS, A. H. (Borden Co.) Oct. 11, 1937, No. 27596. [Class 50] [Also in Groups VI, III, V, and XXII] A dried milk powder or a dried buttermilk powder of increased solubility for use as a binder in making briquettes from finely divided coal, wood waste or other fuel is prepared by adding to whole or skim milk or buttermilk before or during drying a reagent capable of reacting with the calcium in the milk to form a calcium salt less soluble in water than tricalcium orthophosphate, the reagent being present in amount sufficient to react with half or more of the calcium in said powder. In a modification, the reagent may be added to the milk or buttermilk after drying and takes effect when the powder is dispersed in water. The reagents employed are oxalates, fluorides or metaphosphates, e.g. the sodium, potassium or ammonium salts, or the corresponding acids. The process is particularly applicable when atmospheric roller driers are employed. With strongly acid powders, alkali may be added to effect partial neutralization.
