Abstract
A method and composition for suppressing coal dust include a metal-containing compound, such as an organo-manganese, that provides the additional benefit of being a combustion improver. The organometallic compound is mixed with any appropriate dust suppressant liquid. The organometallic compound may include methylcyclopentadienyl manganese tricarbonyl.
Claims13
A method of suppressing dust from coal, the method comprising the steps of:
- providing a manganese-containing compound that is an organometallic compound containing an organo group and at least one manganese ion or atom;
- providing a dust-suppressing liquid selected from the group consisting of surfactants, polymer dispersions, polymer solutions, and mixture thereof;
- combining the manganese-containing compound with the dust-suppressing liquid to form a mixture;
- and
- contacting the mixture of manganese-containing compound and dust-suppressing liquid with coal;
- wherein the mixture is contacted with the coal in an amount effective to suppress the generation of dust from the coal.
