Abstract
The present invention relates to a new class of coordination compound fuel combustion catalysts. This invention successfully solves the main problems described above particularly complex positive influence on all steps of combustion process. The solution is used to improve the energy efficiency of burning solid and liquid fuels to produce heat and electricity, in particular when burning low-grade fuels (i.e. biomass/coal dust), municipal solid waste (MSW) and fuels based on them (RDF) to produce heat and electricity.

A compound catalyst for enhancing the combustion efficiency of solid or liquid fuels, the catalyst comprising:
- (a) at least one metal cation selected from transition metals, rare earth metals, alkali metals, alkaline earth metals, or combinations thereof;
- (b) at least one ligand coordinated to the metal cation, the ligand being selected from organic ligands, inorganic ligands, or metal-containing ligands capable of forming coordination bonds with the metal cation;
- and
- (c) at least one counter-anion selected from halides, nitrates, sulfates, phosphates, carboxylates. or complex organic anions;
- wherein the metal cation, ligand, and counter-anion form a charge-balanced coordination complex, and wherein the coordination complex is isolated in a form selected from a dry powder, a concentrate, or a solution of known concentration, independent of a solid zeolite carrier.
A method for preparing and applying the catalyst of claim to improve fuel combustion, comprising the steps of:
- (a) combining one or more metal salts and one or more ligands in an aqueous or organic solvent to form the coordination complex;
- (b) isolating the coordination complex as a dry powder, concentrate, or solution of known concentration;
- and
- (c) directly applying the isolated coordination complex to a fuel selected from a solid fuel or a liquid fuel, wherein the coordination complex is applied without impregnation into a zeolite or porous inorganic support.
The method as set forth in 8, wherein the coordination complex is dried into powder form and combined with a thermally degradable polymer to form a solid carrier composition.
The method as set forth in 8, wherein the catalyst solution is sprayed onto the solid fuel and dried at ambient or elevated temperature to form a catalytic coating.
The method as set forth in 8, wherein the catalyst is mixed into a molten fuel formulation and allowed to solidify prior to combustion.
