1. A method of generating a catalytically enhanced low emission carbonaceous fuel comprising the steps of:
segregating a quantity of fly ash to a particle size of less than or equal to 149 microns;
segregating a quantity of limestone compound to a particle size of less than or equal to 149 microns;
applying said segregated fly ash and said segregated limestone compound to a carbonaceous fuel;
milling said carbonaceous fuel in the presence of said segregated fly ash and said segregated limestone compound such that said segregated fly ash and said segregated limestone compound are distributed across the surface area of said carbonaceous fuel forming a catalytically enhanced low emission carbonaceous fuel; and
combusting said catalytically enhanced low emission carbonaceous fuel wherein said step of combustion results in:
catalytically reducing formation of NOx emissions compared to combustion of a non-treated carbonaceous fuel; and
catalytically reducing formation of mercury emissions compared to combustion of a non-treated carbonaceous fuel.
