20100189617	METHOD OF IMPROVING COMBUSTION OF SOLID FUELS USING EVENLY DISTRIBUTER CATALYSTS OR OTHER AGENTS - A method is provided for reducing noxious emissions from the combustion of coal or other solid fuels wherein a suspension and/or a dispersing agent is combined with a catalyst having a high surface area to mass ratio so as to optimize the reduction of emissions such as NOx. In addition, the agent and/or catalyst is applied on the surface of the fuel in an evenly distributed manner so as to maximize the contact between the agent and/or catalyst and combustion gases and further maximize reduction of emissions.	07-29-2010
