Abstract:
A method for purifying hydroxyalkyl amide of residual alkanolamine by using nonpolar solvent, an acidic pH, salt solutions and an elevated temperature.
Abstract:
Petroleum additive formulations include a petroleum additive dissolved in a carrier fluid including at least one compound of the formula (I): (R2)p-Ph-(CH2)m—COO—(AO)n—R1 where; R1 is C1 to C10 alkyl; AO is alkyleneoxy; n is 0 or from 1 to 100; m is 0, 1 or 2; and Ph is a phenyl group, which may be substituted with groups (R2)p; where each R2 is independently C1 to C4 alkyl or alkoxy; and p is 0, 1 or 2. Further, crude petroleum or petroleum refinery streams can be treated by adding a petroleum additive dissolved in a carrier fluid of the formula (I) to the product stream. Desirably the carrier fluid is or includes iso-propyl benzoate and/or 2-ethyl hexyl benzoate.
Abstract:
A method for reacting alkanolamine with ester in the presence of a metal silicate compound and, optionally, a catalyst, to produce a hydroxyalkyl amide composition with a decreased level of alkanolamine and residual catalyst.
Abstract:
The present invention is a hybrid diesel fuel and method of manufacture. The fuel composes a petroleum diesel fuel mixed into a biosynthetic waste or virgin oil and further containing a stabilizer. The hybrid fuel consists essentially of about 10% to 50% of Diesel Number 1, Diesel Number 2, or Farm Diesel petroleum fuels, and up to 90% filtered and polished biosynthetic oil, measured by volume. The biosynthetic oil can contain all levels of common commercial vegetable and animal fats in any ratio. The hybrid fuel also contains up to about 0.17% stabilizer, which further contains cetane boosters, cleaning agents to remove deposits from the fuel system, a lubricant, demulsifiers, and anti-gelling agents. The invention functions as biocide to inhibit bacterial growth. The invention is substantially equivalent to Diesel Number 2 in terms of power and engine speed, but is cleaner burning and considerably less costly.
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:
Compositions and methods are disclosed for reducing combustion chamber deposits (CCD) and/or intake valve deposits (IVD) in spark ignition internal combustion engines. A butyrolactam alkoxylate (BLA) and/or a butyrolactam derivative (BLD) of this invention or a mixture with at least one additional compound of this invention is added to a liquid hydrocarbon or liquid hydrocarbon-oxygenate gasoline each in an amount of about 0.0005-0.5 wt % of the gasoline. Preferably the gasoline is unleaded. The preferred additional components include polyethers (PE) and polyisobutylene amine (PIBA).
Abstract:
Aviation fuel, such as jet fuel, blends and methods for improving cold flow properties of such fuels at extremely low temperatures are disclosed. Cold flow properties of, for example, JP-8 based jet fuels are improved by addition to the fuel of a variety of C10-C16 alkyl poly(meth)acrylate esters and polyvinylesters of C10-C16 alkanoic acids. Demonstratable cold flow improvement of such fuels at temperatures of about −53° C. and below is shown.
Abstract:
Injector deposits in a direct injection gasoline engine are reduced by providing as fuel for the operation of said direct injection engine a fuel composition comprising a fuel-soluble compound having the formula (I): wherein R1 and R2 are independently C1-4 alkyl, R3 is a radical of the formula CmH2m wherein m is an integer of 2 to 6, R4 and R5 are each independently (i) hydrogen (ii) C1-4 alkyl, wherein R6 is selected from the group consisting of hydrogen and C1-4 alkyls and R7 is selected from the group consisting of hydrogen and C1-30 alkyl, (iv) wherein R8 is a saturated or unsaturated, linear, branched or cyclic, C7-23 hydrocarbyl group or (v) wherein R4 and R5 together with the nitrogen atom to which they are bonded, form a cyclic ring in which further hetero atoms.
Abstract:
A fuel additive composition including a Mannich product, a polyetheramine, and a friction modifier is disclosed. Also, disclosed are a fuel composition comprising the fuel additive composition, an engine combusting the fuel composition, and a method of preventing and/or forming deposits in an engine.
