ABSTRACT:
A method for reducing the moisture content of coal is described which comprises contacting coal with an aqueous solution of at least 0.1 percent of polyethylene oxide with a molecular weight of at least 200,000 so that at least 1 gram of polyethylene oxide per 1000 grams of coal is deposited upon the coal, and then evaporating the water. The preferred method for contacting the coal with the aqueous solution is by spraying the solution onto the coal.
