20100187925 | Additives for Improving Motor Oil Properties - An electric submersible motor is provided that includes a plurality of rotors and bearings mounted on a shaft, and a stator external to said rotors. A running clearance is located between an inner diameter of the stator and external diameter of the rotors, and includes a lubricating oil that includes a base hydrocarbon oil and a plurality of nanoparticles. Also provided is an improved lubricant oil and method of preparation thereof are provided. The lubricant oil includes a hydrocarbon containing base oil and a plurality of nanoparticles. The nanoparticles may be present in an amount up to 30% by volume. | 07-29-2010 |
20100325944 | Additives for Cetane Improvement in Middle Distillate Fuels - The cetane number of middle distillate fuels may be increased using an additive composition including a polymer that may be a homopolymer or copolymer of olefins, and the like, where the polymer has a weight average molecular weight ranging from about 200,000 to about 5,000,000. The additive composition also includes a free radical initiator component, which may be an alkyl nitrate such as 2-ethylhexylnitrate (2-EHN), and/or a peroxide, such as t-butyl peroxide. In one non-limiting embodiment the amount of polymer in the additive composition is greater than the free radical initiator component. A solvent is also present, which the solvent may include alcohol, an alkyl substituted phenol and/or a heavy aromatic distillate. | 12-30-2010 |
20110172473 | Additives to Enhance Metal Removal in Refinery Desalting Processes - It has been discovered that metals can be removed or transferred from a hydrocarbon phase to a water phase in an emulsion breaking process by using a composition that contains a demulsifier (for instance, an oxyalkylated alkyl resin and/or a crosslinked polypropylene glycol), a surfactant, a diketone and a solvent (for instance an aromatic solvent). The method may also include introducing a hydroxyl carboxylic acid and/or at least one mineral acid to reduce the pH of the desalter wash water. The method permits transfer of metals into the aqueous phase with little or no hydrocarbon phase undercarry into the aqueous phase. The composition is particularly useful in treating crude oil emulsions, and in removing iron therefrom. | 07-14-2011 |

20120034162 | Fullerene Assisted Cell Penetrating Peptides - A composition and method is described for intracellular delivery of fullerene containing peptides. The composition and method involve fullerene-substituted phenylalanine as part of a peptide based delivery system. The presence of a fullerene-substituted amino acid in a peptide is found to alter the intracellular transport properties of the peptide. | 02-09-2012 |
20120066964 | Additives for Reduction of Exhaust Emissions from Compression Ignition Engines - Exhaust emissions resulting from the combustion of hydrocarbon fuels in compression ignition engines may be reduced using a homopolymer that may be polyisobutylene, polypropylene, and/or hyperbranched polyalpha-olefins. The homopolymer may have a molecular weight of from about 1600 to about 275,000. Optionally, an alkyl nitrate such as 2-ethylhexylnitrate (2EHN), and/or a peroxide, such as hydrogen peroxide, may also be used together with the homopolymer. Both NOx and particulate matter emissions (PM) may be reduced using ppm quantities of the additive compositions; alternatively, NOx emissions may be lowered or reduced while PM emissions do not substantially increase. | 03-22-2012 |
20120117861 | Fuel Additives for Enhanced Lubricity and Anti-Corrosion Properties - The reaction product resulting from the chemical reaction of an alkyl phenol with an acid or an anhydride selected from the group consisting of a saturated dicarboxylic acid, an unsaturated dicarboxylic acid, an anhydride of a saturated dicarboxylic acid, an anhydride of an unsaturated dicarboxylic acid, and combinations thereof, has been discovered to improve the properties of various fluids. In a non-limiting example, the reaction products may have an acid number from about 0 to about 50 that may improve the lubricity and/or corrosion of fuels and lubricants, such as hydrocarbon fuels and lubricants, when added thereto. | 05-17-2012 |
