Abstract:
A composition and method for improving the performance, and thus, also the fuel economy, of an internal combustion engine by introducing a fuel additive into the engine's fuel supply to enhance fuel lubricity. The composition can feature a mixture of esters, glycol ether, and a solvent. The mixture of esters can include adipate esters, azelate esters, dodecanedioate esters, sebacate esters, or phthalate esters. Esters that may be used to create the composition can include a mixture of two or more adipate esters such as, for example, an adipic acid ester, a glutaric acid ester, and a succinic acid ester. The composition can further feature a smoke suppressant that can be an organometallic soap. The organometallic soap can be an iron salt of a fatty acid such as, for example, ferrocene. The composition can be used as a combustion modifier fuel additive and as a lubricating oil.
Abstract:
The present invention relates to catalysts, systems, and methods for producing products such as fuels and fuel additives from polyols. In an embodiment, the invention includes a method of producing a fuel additive, including combining a polyol and a component selected from the group consisting of alcohols and organic acids to form a reaction mixture and contacting the reaction mixture with a metal oxide catalyst at a temperature of greater than about 150 degrees Celsius. Other embodiments are also included herein.
Abstract:

Abstract:
The present invention relates to biodiesel fuel compositions that have improved oxidation stability. More specifically, the biodiesel fuel compositions include at least one antioxidant that increases the oxidative stability of the fuel. The biodiesel fuel compositions may also include an antioxidant mixture, or an antioxidant mixture in combination with a polar and/or nonpolar solvent, that increases the oxidative stability of the fuel.
Abstract:
A fuel composition for use in an internal combustion engine containing (a) a diesel fuel, (b) ethanol, (c) a surfactant, and optionally (d) a combustion improver, which provides lubricity to the engine and reduces exhaust emissions.
Abstract:
The present application relates to deposit control additive composition comprising of Mannich base and Polyisobutylene succinimide (PIBSI) having average molecular weight of about 800 as a synergistic component for hydrocarbon fuel, particularly diesel fuel along with other conventional additives such as fluidizer oil, dehazer, corrosion inhibitor, solvents, and optionally lubricity improver, antistatic agent and ignition accelerator to obtain diesel fuel composition. The application also relates to a process for the preparation of fuel composition by blending at an ambient temperature diesel fuel and deposit control additive formulation obtained by blending Mannich base, Polyisobutylene succinimide (PIBSI) fluidizer oil, dehazer, corrosion inhibitor, optionally lubricity improver, antistatic agent, ignition accelerator at a temperature ranging between 50° C. to 60° C. for a time period of up to 2 hours.
Abstract:
Non-polymeric drag reducing agents in the form of maleated fatty acids and the esters thereof and the organic, inorganic or amine salts thereof are described herein. These additives are useful to reduce drag in hydrocarbon fluids and multi-phase fluids of hydrocarbon(s) and water. No injection probes or other special equipment is expected to be required to introduce the drag reducing agent into the liquid stream, nor is grinding (cryogenic or otherwise) of the additive necessary to form a suitable drag reducing agent. The drag reducing additives of the invention are not subject to shear degradation and do not cause undesirable changes in the emulsion or fluid quality of the fluid being treated, or undesirable foaming.
Abstract:
An additive for improving the lubricity of fuel oils having a maximum sulfur content of 0.035% by weight, comprising A) at least one partial ester composed of a di- or polyhydric alcohol and unsaturated and optionally also saturated fatty acids whose carbon chain lengths are between 8 and 30 carbon atoms, at least 60% of the fatty acid radicals containing at least one double bond, and B) at least one alkylphenol-aldehyde resin, obtainable by the condensation of (i) at least one alkylphenol having at least one C6-C24-alkyl or C6-C24-alkenyl radical and (ii) at least one aldehyde or ketone, to a degree of condensation of between 2 and 50 alkylphenol units.
Abstract:
The invention relates to an improver in the form of a mixture of at least polysiloxane antifoaming agent and at least partially or totally neutralised fat acid. The inventive fuel and additive containing said mixture are also disclosed.
