Abstract:
The present invention relates to a control release gel for delivery of additives to fuels where the gel compositions are free of ash producing components, or are substantially free of ash producing components, such that the gel compositions of the present invention do not supply any ash to the fuel compositions with which they are used. Further, the invention provides for the use of such compositions in the operation of an internal combustion engine.
Abstract:
Provided are additives of formula I for use in hydrocarbonaceous compositions, such as petroleum or liquid fuels: (I) wherein R1, R2, R3, R4, and R5 are as defined herein. The additives improve the corrosion resistance of the compositions. The additives also enhance the antimicrobial efficacy of any added biocides contained in such compositions.
Abstract:
The present invention is a hybrid diesel fuel and method of manufacture. The fuel composes a petroleum diesel fuel mixed into a biosynthetic waste or virgin oil and further containing a stabilizer. The hybrid fuel consists essentially of about 10% to 50% of Diesel Number 1, Diesel Number 2, or Farm Diesel petroleum fuels, and up to 90% filtered and polished biosynthetic oil, measured by volume. The biosynthetic oil can contain all levels of common commercial vegetable and animal fats in any ratio. The hybrid fuel also contains up to about 0.17% stabilizer, which further contains cetane boosters, cleaning agents to remove deposits from the fuel system, a lubricant, demulsifiers, and anti-gelling agents. The invention functions as biocide to inhibit bacterial growth. The invention is substantially equivalent to Diesel Number 2 in terms of power and engine speed, but is cleaner burning and considerably less costly.
Abstract:
A fuel composition for use in an internal combustion engine containing (a) a diesel fuel, (b) ethanol, (c) a surfactant, and optionally (d) a combustion improver, which provides lubricity to the engine and reduces exhaust emissions.
Abstract:
The invention relates to an improver in the form of a mixture of at least polysiloxane antifoaming agent and at least partially or totally neutralised fat acid. The inventive fuel and additive containing said mixture are also disclosed.
Abstract:
An emulsified water-blended fuel composition comprising: (A) about 50% to about 99% by weight of a hydrocarbon fuel; (B) about 1% to about 50% by weight of water; (C) about 0.1% to about 10% of a minor emulsifying amount of at least one fuel-soluble salt comprised of (I) a first acylating agent, said first acylating agent having at least one hydrocarbyl substituent of about 20 to 500 carbon atoms and a molecular weight (Mn) in the range of about 500 Mn to 10,000 Mn, (II) a second acylating agent, said second acylating agent selected from the group consisting of monocarboxylic agents, polycarboxylic agents, dicarboxylic agents and combinations thereof; and wherein said second acylating agent has at least 1 hydrocarbyl substituent of up to about 35 carbon atoms and reacting said carboxylic acylating agents (I) and (II) with (III) an ammonia or an amine to form a salt; (D) about 0.001% to about 15% by weight of the water-soluble salt distinct from component (C).
Abstract:
An improved diesel fuel based on a blend of biodiesel and ultra-low sulfur diesel fuel, particularly with a fuel additive containing a concentrate containing fuel borne catalyst (FBC). The catalyst will preferably comprise platinum and/or cerium and/or iron, and the ultra-low sulfur diesel fuel will preferably contain less than 10% aromatics. The biodiesel is typically employed in an amount of about 20% of the blend.
Abstract:
A concentrate composition contains (A) a fatty carboxylic acid based composition selected from (1) a fatty monocarboxylic acid, (2) an ester of (A)(1), (3) an amide of (A)(1), (4) an amine salt of (A)(1), and (5) a mixture thereof, and (B) a low temperature stability improving amount of a composition comprising one or more low temperature stability improving compositions. A fuel composition contains a major amount of a fuel and a minor amount of the concentrate composition. A method to improve the lubricity of a fuel composition containing a fuel comprises adding a lubricity improving amount of the concentrate composition to the fuel. The low temperature stability improving composition (B) is very effective in maintaining clarity, homogeneity and fluidity of a concentrate composition containing a fatty carboxylic acid based composition at low temperatures.
Abstract:
A fuel composition comprising (a) a major amount of an internal combustion engine hydrocarbon fuel containing at least one alcohol, it being provided that MTBE is substantially absent from the fuel and (b) a friction modifying amount of a reaction product of at least one natural or synthetic oil and at least one alkanolamine is provided. Also provided is a method for operating an engine employing the fuel composition therefor.
