There is disclosed an antifoam component which includes at least one poly(acrylate) copolymer for use in a fuel. Poly(acrylate) polymers prepared by polymerizing a (meth)acrylate monomer comprising Cto Calkyl esters of (meth)acrylic acid ('multifunctional monomer') are also disclosed. Other poly(acrylate) polymers prepared by polymerizing (i) a (meth)acrylate monomer comprising Cto Calkyl esters of (meth)acrylic acid (“solubility monomer”); (ii) a (meth)acrylate monomer comprising Cto Calkyl esters of (meth)acrylic acid (“surface tension monomer”); and (iii) optionally at least one additional monomer comprising a solubility monomer, a surface tension monomer, a monomer comprising Cto Calkyl esters of (meth)acrylic acid (“multifunctional monomer”), or combinations thereof are also disclosed.

Polyacrylate antifoam components for use in fuels

The present technology is related to amide or ester containing quaternary ammonium salts having a hydrocarbyl substituent of number average molecular weight ranging from 300 to 750, and the use of such quaternary ammonium salts in fuel compositions to improve the water shedding performance of the fuel composition.

Low molecular weight amide/ester containing quaternary ammonium salts

The present technology is related to imide containing quaternary ammonium salts having a hydrocarbyl substituent of number average molecular weight ranging from 300 to 750, and the use of such quaternary ammonium salts in fuel compositions to improve the water shedding performance of the fuel composition.

Low molecular weight imide containing quaternary ammonium salts

There is disclosed an antifoam component which includes at least one acrylamide polymer for use in a diesel fuel. Acrylamide polymers prepared by polymerizing a (meth)acrylamide monomer to yield a homopolymer or, alternatively, the acrylamide polymer may be prepared by polymerizing a (meth)acrylamide monomer and a (meth)acrylate monomer to yield a heteropolymer.

Polyacrylamide antifoam components for use in diesel fuels

The present technology is related to imide containing quaternary ammonium salts having a hydrocarbyl substituent of number average molecular weight less 300, and additive packages having such quaternary ammonium salts and improved stability.

Ultra-low molecular weight imide containing quaternary ammonium salts having short hydrocarbon tails

The composition of the present invention related to a quaternary ammonium salt detergent and the use of such quaternary ammonium salt detergents in a fuel composition to reduce diesel injector deposits and remove or clean up existing deposits on the diesel injectors.

Diesel detergent without a low molecular weight penalty

There is disclosed an antifoam component which includes at least one poly(acrylate) copolymer for use in a diesel fuel. Poly(acrylate) polymers prepared by polymerizing a (meth)acrylate monomer comprising Cto Calkyl esters of (meth)acrylic acid ('multifunctional monomer') are also disclosed. Other poly(acrylate) polymers prepared by polymerizing (i) a (meth)acrylate monomer comprising Cto Calkyl esters of (meth)acrylic acid ('solubility monomer'); (ii) a (meth)acrylate monomer comprising Cto Calkyl esters of (meth)acrylic acid (&#x201c;surface tension monomer&#x201d;); and (iii) optionally at least one additional monomer comprising a solubility monomer, a surface tension monomer, a monomer comprising Cto Calkyl esters of (meth)acrylic acid (&#x201c;multifunctional monomer&#x201d;), or combinations thereof are also disclosed.

Polyacrylate antifoam components for use in diesel fuels

The invention relates to quaternary ammonium amide and/or ester salts and their use as additives, including their use in fuels, such as diesel fuel. The invention particularly relates to the use of quaternary ammonium amide and/or ester salts as detergents in diesel fuels.

Quaternary ammonium amide and/or ester salts

The invention relates to methods of combusting coal containing fuel streams where a coal additive composition is used to improve the combustion of the coal. The invention also relates to the additive composition used in the described methods, and the use of the additive composition as a coal combustion improver.
