The present invention relates to an aqueous pour point depressant dispersion composition comprising an ethylene vinyl acetate copolymer (EVA); a dispersing agent; a polyethoxylated nonionic surfactant, a low level of hydrocarbon solvent, water; optionally one or more of an aqueous freezing point depressant, a stabilizing agent, or a basic metal substance and a method to use said composition.

The disclosure relates to fuel additive compositions including heavy paraffinic distillates and lighter petroleum distillates, in particular with the heavy paraffinic distillates including a mixture of hydrotreated and/or saturated components and solvent-dewaxed and/or branched components. The disclosure further relates to fuel compositions including the fuel additive composition and a liquid or solid combustible fuel. Related methods include methods of making the fuel compositions and methods of burning the fuel compositions. The resulting fuel compositions have several improved combustion properties such as improved combustion efficiency, improved combustion energy/calorie content, reduced sulfur generation, and reduced ash generation.

A fuel stabilizer formulation includes a hybrid component that acts as an antioxidant, a chelating agent, and lubricant when added to the fuel, one or more vapor suppressants, and a water scavenger. Furthermore, the formulation may include components that bond with gasoline compounds to prevent evaporation of low-end components, form a layer along with the engine metal that prevents condensed water from corroding the metal, prevent corroded metal ions from destabilizing gasoline compounds into resin, and scavenge water to prevent water deposits at the bottom of the tank which limits biological activity, resulting in an overall improvement in oxidation stability over conventional fuel stabilizers.

A method of producing a nanoemulsion is disclosed that provides an oleaginous base fuel, and water in an amount of at least 10 wt %. A first nonionic surfactant, a second nonionic surfactant and a third nonionic surfactant are mixed in substantially equal weight ratios into a surfactant mixture. The surfactant mixture is mixed with the water and the base fuel to form the nanoemulsion fuel. A nanoemulsion fuel composition can comprise an external oleaginous phase comprised of base fuel, an internal aqueous phase comprised of water, and a surfactant mixture comprised of a plurality of surfactants. The first surfactant can be derived from ethylene oxide, the second surfactant and the third surfactant are detergents having a fatty acid.

Provided are automated systems and methods for measuring the physical properties of fuels in large storage tanks, and for blending butane into the fuels, including chemometric methods for controlling physical properties selected from volatility, butane content, and density of the fuel during the blending process.

A method of producing a fuel additive includes passing a feed stream comprising C4 hydrocarbons through a hydrogenation unit producing a hydrogenated stream; passing the hydrogenated stream through a distillation unit producing a first stream and a second stream; producing an isobutylene stream by passing the first stream through a molecular sieve unit; passing the isobutylene stream to a hydration unit as a feedstock for the fuel additive; and forming the fuel additive in the hydration unit.

A multipurpose fuel composition is disclosed which contains a petroleum derived jet fuel component and a renewable jet fuel component, wherein the multipurpose fuel composition has a freezing point of −40° C. or below, and an exemplary cetane number more than 40, preferably more than 45, more preferably more than 50.

The present disclosure is directed to a composition and method for producing a nanoemulsion comprising fuel and water. The composition and method can produce a transparent and stable water in fuel nanoemulsion. The disclosure is directed to various surfactants and water contents that may be usable to improve fuel efficiency and reduced carbon emissions that plague known fuels.
