Patent ID: 7803201

Claim:
A fuel composition having modified combustion properties, comprising: a fuel substrate comprising at least one member selected from the group consisting of tobacco, coal, briquetted charcoal, wood, biomass, fuel oil, diesel, jet fuel, gasoline, and distilled liquid hydrocarbons; a plurality of organically complexed metal catalyst nanoparticles on and/or mixed with said fuel substrate, said metal catalyst nanoparticles having a size less than 1 micron, each organically complexed metal catalyst nanoparticle consisting essentially of: a plurality of active catalyst atoms, at least about 50% of which comprise one or more types of primary catalyst atoms selected from the group consisting of chromium, manganese, iron, cobalt, nickel, copper, zirconium, tin, zinc, tungsten, titanium, molybdenum, and vanadium; and a dispersing agent consisting essentially of a plurality of organic molecules complexed with at least a portion of said active catalyst atoms of said metal catalyst nanoparticles, each of said organic molecules having one or more functional groups capable of bonding to said active catalyst atoms, wherein the organic molecules are bonded to the metal catalyst nanoparticles, wherein the organic molecules are selected from the group consisting of formic acid, acetic acid, oxalic acid, malonic acid, glycolic acid, glucose, citric acid, and glycine.
