Patent ID: 8545577

Claim:
An aviation fuel composition comprising: an aviation fuel selected from the group consisting of 100LL Avgas, 82UL Avgas, 80/87 Avgas, 100/130 Avgas, 91-96 Avgas, 115-145 Avgas, Jet A, Jet A1, Jet B, JP-4, JP-5, and JP-8; and from about 1 ppm to about 280 ppm (expressed as zinc) of nano-sized zinc particles, where at least about 90% by weight of the nano-sized particles have a size from about 1nm to about 50 nm, to simultaneously reduce resultant aircraft engine exhaust emissions of carbon dioxide by about 3% to about 60% and nitrogen oxides by about 3% to about 40% during combustion compared to exhaust emissions of the aviation fuel without inclusion of the nano-sized zinc particles, wherein the nano-sized zinc particles comprise nano-sized zinc peroxide particles with the proviso that the nano-sized zinc particles do not substantially contain organo-zinc compounds, and the nano-sized zinc particles comprise less than about 20% by weight of nano-sized zinc peroxide particles based on the total nano-sized zinc particles.
