摘要： A method and apparatus for mixing additives into a fluid fuel at a predictable concentration. The method involves taking a sample of the fuel; mixing the additive into the sample in metered proportions; testing the sample to determine that the correct amount of additive is present; storing the remaining fuel until it is time for the fuel to be used; and mixing the additive into the remainder of the fuel in the same metered proportions.

摘要： A method of producing a fuel additive includes producing a first product stream comprising butadiene by passing a feed stream comprising C4 hydrocarbons through a steam cracker; transforming greater than or equal to 90 weight % of the butadiene in the first product stream into a second product stream by passing the first product stream through a first hydrogenation unit, wherein the second product stream comprises 1-butene, 2-butene, n-butane, isobutylene, isobutane, or a combination thereof; and converting the second product stream into the fuel additive by passing the second product stream through a fuel additive synthesis unit with an acid catalyst.

摘要： A composition for cleaning a combustion engine system. The composition comprises a hydrocarbon. The hydrocarbon comprises respective first and second hydrocarbons. The first hydrocarbon comprises a lubricant, wherein the lubricant has a flash point, measured according to ASTM D93, of less than 80° C. The second hydrocarbon comprises an aromatic hydrocarbon, wherein the aromatic hydrocarbon has a flash point, measured according to ASTM D93, of greater than 62° C. The composition further comprises an oxygen donor. The oxygen donor comprises respective first and second oxygen donors. The first oxygen donor comprises a hydroxyl group and has a flash point, measured according to ASTM D93, of from 45° C. to 95° C. The second oxygen donor comprises a carbonyl group or an ether group and has a flash point, measured according to ASTM D93, of from 50° C. to 120° C.

摘要： A process of removing at least one metal contaminant, such as copper, from a fluid hydrocarbon, for example, crude oil or a liquid hydrocarbon fuel, such as an aviation fuel. The process involves contacting the metal-contaminated fluid hydrocarbon with a sorbent selected from graphene oxide or a functionalized graphene oxide, particularly, a graphene oxide treated with a polycarboxylic acid, such as a saccharide polycarboxylic acid or a salt thereof, examples of which include alginic acid and Group IA and IIA salts thereof. The process removes greater than 99 percent of the metal contaminant without reducing concentrations of advantageous fuel additives, such as, antioxidants, icing inhibitors and corrosion inhibitors. Also described are a purified fluid hydrocarbon composition and a metal contaminant filter system.

摘要： This disclosure relates to compositions and methods of making an additized fuel composition comprising a base fuel composition and a randomly branched nitrate composition. The randomly branched nitrate composition includes a plurality of primary nitrate molecules, each molecule therein having an empirical chemical formula of CnNO3, wherein Cn is a branched aliphatic moiety which may be the same or different for each molecule, n is an integer selected from the group consisting of 8, 9, 10, 11 and 12, at least one carbon atom in the branched aliphatic moiety being bound to three or more carbon atoms, a branching index ranging from 1.8 to 2.2, and greater than 80% of the branches in the aliphatic moiety being in other than the alpha position. The additized fuel composition may be diesel fuel composition or a gasoline fuel composition.

摘要： Fuels, hydraulic fluids and lubricants made of or comprising a portion of renewable hydrocarbon raw materials, as well as biodegradable fuels, hydraulic fluids and lubricants are known to support microbial growth. Highly toxicorganic biocides have been added to reduce microbial growth. The use of such biocides can now be avoided, by instead using a stable solution of boric acid in a solvent, the boric acid being completely dissolved or at least free from any particles larger than 100 nm in size, and adding this solution to the fuel, hydraulic fluid or lubricant to give a final concentration of boron in the range of 1-100 ppm, preferably 1-50 ppm in the product. While preventing microbial growth, the addition of boron also reduces corrosion, in particular microbiologically induced corrosion (MIC).
