Benefits of technology

[0008] A diesel fuel additive is provided which may be combined with conventional diesel fuels so as to yield a diesel fuel with improved cetane number. Because an additive is used to produce improved diesel fuels, the equipment and product costs associated with a refinery solution are avoided. The additive may also be combined with other hydrocarbon fuels, such as gasoline fuels, jet fuels, two-cycle fuels, coals, and other hydrocarbonaceous fuels to reduce the emission of pollutants during combustion of the fuel, to improve combustion, to improve fuel economy, and / or to provide other benefits.

Problems solved by technology

Conventional refinery-based processes for producing quality diesel fuels of acceptable cetane number suffer from a number of drawbacks.

[0185] Fuel additives of certain preferred embodiments may be prepared according to the following descriptions. In other embodiments, other methods of preparing the additives may be preferred. Modifications to these methods, including the order of addition of ingredients, substitutions of ingredients as described above, the use of various diluents, the equipment utilized, mixing conditions, and other aspects of the methods, are all contemplated.

[0186] Various cetane improving additive formulations were tested in base diesel fuels. Cetane testing was performed by independent petroleum laboratories, each of which was CARB, EPA, and ASTM Certified. The procedure for testing Cetane is ASTM D-613, a published procedure that measures the ignition point of No. 2 diesel fuel. The test data, provided in Tables 1 and 2, verify that the cetane improver described herein synergistically improves the level of cetane in No. 2 diesel fuel.

Abstract

A diesel fuel additive is provided that includes beta-carotene stabilized with 2,2,4-trimethyl-6-ethoxy-1,2-dihydro-quinoline. The additive may be added to any liquid hydrocarbon fuel, solid hydrocarbon fuel, or other hydrocarbonaceous combustible fuel to reduce emissions of undesired components during combustion of the fuel, provide improved fuel economy, engine cleanliness, and / or performance. A method for preparing the additive is also provided.

Description

FIELD OF THE INVENTION [0001] A diesel fuel additive is provided that includes beta-carotene stabilized with 2,2,4-trimethyl-6-ethoxy-1,2-dihydroquinoline. The additive may be added to any liquid hydrocarbon fuel, solid hydrocarbon fuel, or other hydrocarbonaceous combustible fuel to reduce emissions of undesired components during combustion of the fuel, provide improved fuel economy, engine cleanliness, and / or performance. A method for preparing the additive is also provided. BACKGROUND OF THE INVENTION [0002] Hydrocarbon fuels typically contain a complex mixture of hydrocarbons, namely, molecules containing various configurations of hydrogen and carbon atoms. They may also contain various additives, including detergents, anti-oxidants, anti-icing agents, emulsifiers, corrosion inhibitors, dyes, deposit modifiers, and non-hydrocarbons such as oxygenates. [0003] When such hydrocarbon fuels are combusted, a variety of pollutants are generated. These combustion products include ozone,...
