Abstract
A hydrocarbonaceous fuel additive, fuel composition, and method all lower both carbon particulate emissions and improve slag properties in combustion systems including, for instance, utility furnaces and boiler systems. The mixed metal catalyst may include a transition metal-containing compound, an alkali metal compound, and a magnesium-containing compound.
Claims41
A hydrocarbonaceous fuel additive for a fuel composition comprising:
- a transition metal-containing organometallic compound;
- an alkali metal compound;
- and
- a magnesium-containing compound, wherein the magnesium-containing compound is supplied in an amount sufficient to supply about 20 to 600 ppm of magnesium metal to the fuel composition.
(canceled)
(canceled)
A fuel composition which comprises a major amount of hydrocarbonaceous fuel and minor amount of an additive, the additive comprising:
- a transition metal-containing organometallic compound;
- an alkali metal compound;
- and
- a magnesium-containing compound, wherein the magnesium-containing compound is supplied in an amount sufficient to supply about 20 to 600 ppm of magnesium metal to the fuel composition.
(canceled)
(canceled)
A method of improving the combustion of and the slag resulting from the combustion of a hydrocarbonaceous fuel, the method comprising the steps of:
- providing a hydrocarbonaceous fuel comprising a transition metal-containing compound, an alkali metal compound, and a magnesium-containing compound;
- combusting the fuel in a combustion system, wherein the combustion of the fuel causes the formation of slag;
- wherein the amount of transition metal, alkali metal and magnesium contained in the fuel composition is in an amount effective to improve the combustion of the fuel composition and improve the slag resulting from combustion of the fuel.
A hydrocarbonaceous fuel additive comprising:
- methylcyclopentadienyl manganese tricarbonyl;
- an alkali metal compound;
- and
- a magnesium-containing compound, wherein the magnesium-containing compound is supplied in an amount sufficient to supply about 20 to 600 ppm of magnesium metal to the fuel composition.
(canceled)
(canceled)
Slag produced from the steps comprising:
- providing a hydrocarbonaceous fuel comprising a transition metal-containing organometallic compound, an alkali metal compound, and a magnesium-containing compound, the magnesium-containing compound supplied in an amount sufficient to supply about 20 to 600 ppm of magnesium metal to the fuel composition;
- and
- combusting the fuel in a combustion system, wherein the combustion of the fuel causes the formation of slag which is easily removed.
