A composition including a major amount of carbon dioxide and at least one branched polyolefin polymer is described, as well as methods of making and using the composition, such as in increasing the viscosity of carbon dioxide for use in carbon sequestration and/or enhanced oil recovery.

Carbon dioxide viscosification by polyolefins

This invention relates to compositions and methods for inhibiting corrosion and deposit formation in fuel handling equipment, with reduced or eliminated incidence of fuel filter plugging and internal diesel injector deposits (IDID) in the equipment that eventually employs the final commercially blended form of the fuel. More specifically, the invention relates to inhibiting corrosion from the walls of fuel pipelines and storage equipment and preventing deposits in engines.

Ion tolerant corrosion inhibitors and inhibitor combinations for fuels

A fuel additive composition comprises (a) a Mannich reaction product and (b) a polyetheramine where the weight ratio on an actives basis of component (a) to component (b) is 1:4-10. A fuel composition and a method for removing intake valve deposits and combustion chamber deposits in a spark-ignited internal combustion engine comprise the fuel additive composition which is very effective in removing the deposits.

Additive and fuel compositions containing detergent and fluidizer and method thereof

An additive composition comprises a Mannich reaction product of a) a polyisobutylene (PIB) alkylated hydroxyaromatic compound, b) an aldehyde, and c) an amine containing at least one reactive amino group where the PIB is derived from a conventional PIB and a high vinylidene PIB. A fuel additive concentrate composition, a fuel composition, and a method to reduce deposit formation in a fuel system of an internal combustion engine employ the additive composition that comprises the Mannich reaction product which is unexpectedly effective in reducing deposits. A PIB alkylated hydroxyaromatic compound, that is prepared from a mixture of high vinylidene and conventional PIBs, is both a functional additive and an intermediate to a functional additive and the process to prepare it involves running the alkylation reaction at 5 to 40&#xb0; C.

Alkylated hydroxyaromatic compound from conventional and high vinylidene polyisobutylenes and compositions and processes thereof

The use of alkoxylates and nitrogen containing detergents in a fuel additive composition to prevent intake valve sticking and reduce intake valve deposits.

Use of fatty acid alkoxylates as a method to remedy engine intake valve sticking

The present invention is directed to a method to clean up or keep clean the fuel system of a direct injection spark-ignited engine by operating the engine with a fuel composition that includes a liquid fuel and a fuel additive composition. The fuel additive composition useful in the present invention has at least one nitrogen-containing dispersant and optionally a fluidizer where the dispersant has a specific lipophilic parameter and the dispersant or the dispersant and the fluidizer have a specific hydrophilic-lipophilic parameter, the dispersant provides about 0.15 to about 50 ppm by weight nitrogen in the fuel composition, and the fluidizer and/or the dispersant provide about 10 to about 10,000 ppm by weight active components in the fuel composition. The method of the present invention is effective in controlling deposits in fuel injectors and combustion chambers of a direct injection spark-ignited engine.

Method of operating a direct injection spark-ignited engine with a fuel composition

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.

Ethanol-diesel fuel composition and methods thereof

A gasoline additive concentrate composition comprises a solvent, an alkoxylated fatty amine, and a partial ester having at least one free hydroxyl group and formed by reacting at least one fatty carboxylic acid and at least one polyhydric alcohol. A fuel composition comprises gasoline and the gasoline additive concentrate composition. A method of operating a gasoline internal combustion engine comprises fueling the engine with the fuel composition and is effective in reducing fuel consumption.

Gasoline additive concentrate composition and fuel composition and method thereof

Fuel additive compositions and fuel compositions containing detergents and fluidizers

Compositions containing polyalkene-substituted amine and polyether alcohol

Additive composition

A fuel additive composition comprising at least one amine, whereun said at least one amine contains at least one polyolefin group and at least one polyetheramine. These compositions are useful as fuel additives for reducing intake valve deposits. In addition, these compositions do not contribute to an increase in combustion chamber deposits in port fuel injected internal combustion engines.

Fuel additives and fuel compositions comprising said fuel additives

The present invention is directed to a composition made by reacting A) an aldehyde of 1 to 12 carbon atoms or a reactive equivalent thereof; and B) at least one etheramine represented by the formula
