Abstract:
A method of formulating a fuel composition for use in internal-combustion engines includes the step of providing a fuel. In addition, there is the step of forming the fuel composition by adding to the fuel a polar fluid and an emulsifier. The emulsifier is present in an amount effective for the biodiesel fuel, alcohol, water, and emulsifier to form an emulsion. The emulsifier includes an active surfactant mixture of oleic acid and ammonium oleate, wherein the ratio of oleic acid to ammonium oleate is no more than 60:40.
Abstract:
The use of alkoxylates and nitrogen containing detergents in a fuel additive composition to prevent intake valve sticking and reduce intake valve deposits.
Abstract:
Biofuel compositions and methods. Biofuel compositions comprised of glycerine, water and one or more alcohols can be prepared and utilized as an alternative or renewable fuel or mixed with other fuels and fuel products. The methods of preparation require simple mixing as the biofuel composition is a solution. The components can be mixed in any sequence. By varying the amount of water and/or alcohol mixed with the glycerine allows for preparation of biofuel compositions having consistent or uniform properties, such as pour point and/or flashpoint even using glycerine from different sources and having different specifications.
Abstract:
A polymeric surfactant obtained by the reaction of: (i) a polyolefin oligomer functionalized with at least one group deriving from a dicarboxylic acid, or a derivative thereof; and (ii) a polyoxyalkylene of linear oxyalkylene units. The polyoxyalkylene is linked to a long-chain alkyl group optionally containing one or more ethylenic unsaturations. The polymeric surfactant may be utilized to stabilize a fuel of an emulsion between water and a liquid hydrocarbon. The fuel has high stability over time, without forming carbonaceous deposits which adhere to metal surfaces.
Abstract:
This invention disclosure describes a conditioned single phase hydrocarbon-based fuel, a method for producing such fuel and components useful in such method. The described conditioned hydrocarbon-based fuel is a single phase hydrous fuel with improved performance, handling and storage characteristics. A method is also is also provided for producing the conditioned hydrocarbon-based fuel using a semi-solid activator. The resulting conditioned hydrocarbon-based fuel has a volume greater than the unmodified hydrocarbon-based fuel, a BTU content greater than the BTU content of the unmodified hydrocarbon-based fuel, less particulate emissions and less non-particulate emissions than the unmodified hydrocarbon-based fuel, and a water content less than the water content of the unmodified hydrocarbon-based fuel.
Abstract:
An emulsifying composition intended to homogenize and reemulsify a fuel, includes by weight, with respect to the total weight of the composition, a) from 5% to 40% of N-oleyl-1,3-propylenediamine, b) from 50% to 95% of N,N′,N′-polyoxyethylene-N-tallowpropylenediamine and c) from 5% to 40% of a solvent. A fuel including the abovementioned composition, a process for the manufacture of the composition and its use are also described.
Abstract:
A method of making phenol and alkylphenol ethoxylates non-estrogenic by inserting 1 mole of propylene oxide onto the phenolic group before proceeding with the addition of ethylene oxide or mixtures of ethylene and propylene oxide. The final phenolic products can be further reacted to form sulfates, sulfonates, phosphate esters, condensed alkylphenol alkoxylates and other derivatives of alkylphenol or phenol. Non-estrogenic phenol and alkylphenol alkoxylates and their derivatives have been found to be excellent salt tolerant, high temperature stable surfactants for oil recovery from subterranean reservoirs. These products are also useful in forming emulsions of heavy crude for transportation through pipelines.
Abstract:
Genetically engineered microorganisms are provided that produce products from the fatty acid biosynthetic pathway (fatty acid derivatives), as well as methods of their use.
Abstract:
Disclosed is an emulsion-type water-mixed fuel which is free from separating between an oil and a water, thereby being excellent in stability, has a high combustion efficiency, and an extremely high energy-saving effect. An emulsion fuel, in which an average diameter of the water or the combustible oil is 1,000 nm or less (more preferably, average diameter is 200 to 700 nm), is formed by finely-dividing and mixing the water and the combustible oil by a finely-dividing and mixing means, while adding 10.0 to 150.0 parts by volume of the water with respect to 100 parts by volume of the combustible oil (more preferably, 25.0 to 120.0 parts by volume of the water with respect to 100 parts by volume of the combustible oil). Further, the water to be used preferably has a reduction potential of −100 my or lower, more preferably −300 my or lower.
Abstract:
The invention provides a water blended fuel composition made by combining (i) a normally liquid hydrocarbon fuel; (ii) water; (iii) a nitrogen-free surfactant; and an acid having a pKa of up to about 6.
