Abstract:
Diesel cycle fuel compositions are described containing at least one dianhydrohexitol compound according to the general formula 2 and/or its derived hydrocarbyl ethers or nitric ethers compounds, where the R′ and R″ substituents are both H or one or both of R′ and R″ is alkyl, cycloalkyl or phenyl, or one or both are —NO2. A preferred fuel composition is that containing dimethyl isosorbide (DMI) added or not of isosorbide dinitrate (ISDN) as ignition improver. The dianhydrohexitols compounds form compositions with at least one of the components selected among petroleum-derived diesel fuel, biodiesel, ethanol and water. The mixture of DMI and ISDN has excellent cetane number (IQT). Still, the oxygenated nature of the dianhydrohexitols and related compounds of the fuel compositions inhibits soot formation upon burning of the said Diesel cycle fuel compositions.
Abstract:
The present disclosure relates to a gasoline combustion improver comprising an organic nitro compound with C—NO2 bond dissociation energy of about 60 to about 80 Kcal/mol of compound, wherein the organic nitro compound is selected from the group consisting of nitro-aromatics, heteroatom aromatic ring compounds, heteroatom nonaromatic ring compounds, and nitrated furfuryls, and wherein the organic nitro compound is not nitrotoluene or dinitrotoluene.
Abstract:
The present invention provides hybrid diesel fuels and methods for manufacturing hybrid diesel fuels. In embodiments, fuel compositions comprise at least one petrochemical fuel, at least one biosynthetic oil and at least one stabilizer mixture. The percentage by volume of the petrochemical fuel can be greater than 0% and less than 100%, and the percentage by volume of the stabilizer mixture can be between about 0.001% and about 0.5%.
Abstract:
A diesel fuel lubricant as a replacement for sulfur lubrication in Ultra-Low and Low Sulfur Diesel fuels, the process for producing said lubricant, and the method of using said lubricant. This lubricant comprises alpha-olefins; low odor aromatic solvents; and at least one a base oil selected from the base oil group consisting of hydroisomerized high base oils and HT Severe Hydro-cracked Base Oils; as well as other ingredients. Also disclosed is a method for producing this lubricant.
Abstract:
A method for marking a petroleum hydrocarbon, biodiesel fuel or ethanol fuel by adding to the petroleum hydrocarbon, biodiesel fuel or ethanol fuel at least one compound having formula (I) wherein R1 and R2 independently represent at least one substituent selected from the group consisting of hydrogen, C1-C12 alkyl, C1-C12 alkoxy and nitro; and R3 and R4 independently represent hydrogen, methyl or ethyl.
Abstract:
Disclosed herein is a fuel oil composition comprising a renewable fuel or a blend of petroleum based fuels with renewable fuels, also containing an additives composition to enhance the base and combined fuel's resistance to forming insoluble particulates upon storage at diminished operating temperatures. Further described is the additive package used to inhibit particulate formation.
Abstract:
The use of mixtures of (A) aliphatic saturated or unsaturated monocarboxylic acids having 12 to 24 carbon atoms or the dimerization or trimerization products thereof, which may be present in the form of free carboxylic acids and/or in the form of ammonium salts, amides, esters and/or nitriles, and (B) polycyclic hydrocarbon compounds which are obtainable from distillation residues of natural oils, which have been extracted from tree resins, for increasing the cetane number of fuel oils which comprise at least one additive with detergent action and at least one cetane number improver, the mixtures of components (A) and (B) being used in a concentration of 10 to 500 ppm by weight, based on the total amount of the fuel oil.
Abstract:
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.
