Disclosed herein is a method for preparing a piston-driven engine blended aviation gasoline composition. Blendstock for automotive gasoline containing an oxygen content in an amount that ranges from 0% by weight to 5.0% by weight and a lead content in an amount that ranges from 0 grams per gallon to 0.05 grams per gallon is blended with an octane enhancer and a pressurant, thereby making the piston-driven engine blended aviation gasoline composition. No additional amount of oxygenate or lead is added to the provided blendstock for automotive gasoline, and the method does not include a step of adding an additional amount of oxygenate or lead to the piston-driven engine blended aviation gasoline composition.

A method for preparation of a reagent for reducing hydrodynamic drag of a turbulent flow of liquid hydrocarbons in pipelines, characterized by a high polymer content of at least 75 wt %, including mixing a 0.1-1.5 mm polymer reducing the hydrodynamic drag of a turbulent flow of liquid hydrocarbons with polymer non-solving solvents. The prepared product is a commodity form of the reagent with a high polymer content of at least 75 wt % used to reduce the hydrodynamic drag of the flow of liquid hydrocarbons in pipelines. The product prepared according to the described method is injected into the flow of hydrocarbon fluid transported through the pipeline using the injection apparatus that mechanically moves the product using a screw auger or screw feeder.

This invention is related to an additive composition comprising metal-based quantum clusters (QCs) dispersed in a hydrocarbon medium. The additive composition is useful as a fuel additive, as it acts as a combustion improver for liquid and gaseous fuels. The invention describes a process for the synthesis of the additive composition comprising metal-based materials in atomic cluster form in hydrocarbon dispersible medium. The stable liquid dispersion of the QC has been doped into the hydrocarbon fuels at required concentrations. The measurable flame temperature of the fuels, e.g., commercial LPG on burner has been observed to increase by at least 60-80° C. The flame with high heat through put can be used for efficient cooking, heating, annealing and other high thermal applications. The additive composition may also be used to improve the fuel economy of the liquid hydrocarbon fuels.

An electrolyte as an additive for internal combustion engines for a production of hydrogen concentrations by a hydrogen generation device. A method of making the electrolyte includes weighing sodium borohydride, sodium hydroxide, and potassium hydride; adding the sodium hydroxide and the potassium hydride to deionized water to make a first composition; mixing the first composition; adding the sodium borohydride to the first composition to make a second composition; adding more deionized water to the second composition to make a basic electrolyte solution; diluting the basic electrolyte solution by adding more deionized water to make a third composition; and adding approximately 3 to 10 mL of sodium borohydride approximately 4.4008 M to the third composition to make an electrolyte having a final concentration sodium borohydride of approximately 0.05947 M.
