Abstract:
The present invention is generally directed to systems and methods for thickening liquids, e.g., hydrophobic liquids, non-aqueous liquids, fuels, etc. In one set of embodiments, a composition is produced by combining in a mixture, at least one monoglyceride (abbreviated “MG”) and glycerine (abbreviated “G”), in which the molar ratio of G to MG in the mixture is between 1:1 and 4:1. The mixture may be melted and cooled to form solids containing a G2MG molecular complex in which two molecules of G are hydrogen-bonded to each molecule of MG. The composition may be substantially free, in certain embodiments, of contaminating reactants, catalysts, alkaline agents, and/or by-products of fatty acid interesterification that may interfere with the use of said composition as a thickening agent.
Abstract:
An additive, comprising a fatty acid and/or a derivative of a fatty acid and an amine, is used in a fuel for the purpose of increasing the efficiency of an engine combusting said fuel, in particular for the purpose of reducing the losses arising from the sliding of the pistons of an engine within their cylinders, and preferably with the result that fuel economy is improved.

Abstract:
Fuel composition and methods of making fuel compositions including 50-90 wt % pyrolysis oil, 0.1-40 wt % water, 1-30 wt % alcohol, and 0.1-4 wt % surfactant, wherein the composition is an emulsion. The pyrolysis oil may be a crude pyrolysis oil and may be produced by pyrolysis of biomass material. The pyrolysis oil and surfactant may form the continuous phase and the water and alcohol may form the dispersed phase of the emulsion. Alternatively, the water and alcohol may form the continuous phase and the pyrolysis oil and surfactant may form the dispersed phase of the emulsion.
Abstract:
A fuel additive for gasoline that increases automobile fuel efficiency and decreases carbon emissions. The fuel additive comprises a composition of olive oil and fuel oil in a ratio, by volume, of about 1 part olive oil to about 8 parts fuel oil. In the preferred embodiment the fuel oil is fuel oil no. 2-D.
Abstract:
A composition for improving the combustion efficiency of an internal combustion engine. The composition includes a mixture of a hydrocarbon fuel and an organometallic soap selected from among several cerium-containing and ferric compounds. The cerium-containing compound or compounds increase the energy released during combustion of the fuel. The ferric compound or compounds coat an interior wall of a combustion chamber of the internal combustion engine to increase the power output of the engine by reducing the accumulation of residues deposited on the interior wall which interfere with the combustion of fuel.

Abstract:
Reacting an alkylene carbonate, such as ethylene carbonate, with dimer acid in the presence of a catalyst, such as a tertiary amine catalyst, gives a dimer acid diester having essentially no sulfur, and thus may be added to ultra-low sulfur diesel fuel downstream of a refinery. The diester enhances the lubricity properties of hydrocarbon fuels, increases their service life and fuel efficiency. The manufacturing process time may be decreased significantly compared with a process using ethylene glycol instead of ethylene carbonate, and much less ethylene glycol by-product results.
