Abstract:
Compositions including an iron containing fuel additive and a solid carrier are disclosed. Methods of preparing tablet forms of the compositions are also disclosed. The iron containing fuel additive may be ferrocene and/or substituted ferrocene derivatives. The compositions are useful for handling and rapidly solvating the iron containing fuel additive in a fuel such as gasoline.

Abstract:
Cold high energy fuel compositions for jet, turbine, diesel, fuel oil, and gasoline combustion systems. More particularly, relates to fuels comprised of enhanced combustion structure.
Abstract:
Hydrocarbonaceous fuels and additive compositions therefor which comprise: a) one or more fuel-soluble manganese carbonyl compounds; b) one or more fuel-soluble alkali or alkaline earth metal-containing neutral or basic detergent salts; and c) one or more fuel-soluble metal deactivators of the chelation type. These compositions preferably contain, in addition to components a), b) and c) above, one or more of the following: d) at least one fuel-soluble ashless dispersant; e) at least one fuel-soluble demulsifying agent; and f) at least one aliphatic or cycloaliphatic amine. Component c) enhances the stability of fuel compositions containing at least components a) and b). The compositions possess improved combustion characteristics (e.g., formation of less soot, smoke, carbonaceous products and/or noxious emissions), and form on combustion carbonaceous products of reduced acidity. The deposition of sludge on critical engine or burner parts or surfaces is reduced and the fuels have improved demulsibility characteristics. And the fuel compositions can result in decreased fuel consumption in diesel engines.
Abstract:
The present invention provides antioxidant compositions that increase the oxidative stability of biodiesel, stabilized fuel compositions, and methods of using the antioxidant compositions to increase the oxidative stability of fuel compositions.
Abstract:
Compositions containing unsaturated fatty esters may be stabilized against atmospheric oxidation by the addition of an antioxidant package containing a phenolic oxidant and a nonphenolic oxygen scavenger, which may be a hydroxylamine, an amine N-oxide, an oxime, or a nitrone. If an amine N-oxide is used, it may be used with or without a phenolic antioxidant. Compositions treated in this manner show good resistance to atmospheric oxidation and resultant viscosity increase.

Abstract:
The present invention relates to processes and additive compositions capable of performing at least one of the following: a) stabilizing asphaltenes flocculated and/or precipitated in a petroleum product (as a crude oil, a residue or a fuel oil), rendering thus possible its blending with other petroleum products or its processing or its combustion; b) reducing fouling in petroleum apparatuses; c) achieving yield increase in petroleum refining and/or petrochemical operations; d) reducing particulate and/or SOx and/or NOx emissions during combustion of fuels; e) reducing fouling and/or coke formation in catalysts; f) favouring cleaning and/or decoking of petroleum apparatuses; g) reducing fouling arising from diesel and biodiesel fuels.
