A motor fuel comprising gasoline comprising 70-99 wt % gasoline and 1 to 30 wt % of mesitylene. This fuel can advantageously contain conventional additives used in gasoline. The use of mesitylene in gasoline blend yields a fuel blend with a higher research octane number and motor octane number. In addition, an improved jet fuel is provided, having from 1-10 wt % mesitylene added to the jet fuel, having improved carbon emission characteristics while maintaining required specifications. Further, an improved bio-fuel is provided, which may function as a replacement for conventional Jet A/JP-8 fuel and has lowered carbon emission specifications, the bio-fuel comprised of 75-90 wt % synthetic parafinnic kerosene (SPK) and 10-25 wt % mesitylene.

An aromatic pre-blend for use in preparing E10 test fuel in accordance with 40 CFR 1065.710(b) includes a mixture of aromatic compounds having C6-C10+ aromatic proportions as recited in 40 CFR 1065.710(b).

The present disclosure generally relates to the production of fuels, gasoline additives, and/or lubricants, and precursors thereof. The compounds used to produce the fuels, gasoline additives, and/or lubricants, and precursors thereof may be derived from biomass. The fuels, gasoline additives, and/or lubricants, and precursors thereof may be produced by a combination of intermolecular and/or intramolecular aldol condensation reactions, Guerbet reactions, hydrogenation reactions, and/or oligomerization reactions.

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.

A method for synthesizing cyclic hydrocarbons with linear hydrocarbon side chains from a renewable source, or biomass by naturally occurring or bioengineered fungal strains, or hydrodistillation of plants.

Haze may be removed from a biofuel or biofuel intermediate by using a clarifier. The clarifier includes copolymer prepared using a formulation comprising an alpha olefin and maleic anhydride. The clarifier may also be used with admixtures of biofuels, biofuel intermediates, or biofuel feedstocks with conventional hydrocarbons.

Use of a liquid fuel composition comprising (a) a gasoline base fuel and (b) from 0.5 to 50% v/v of naphtha as a fuel for a spark ignition internal combustion engine, wherein the spark ignition internal combustion engine is comprised within the powertrain of a hybrid electric vehicle.

A drag reducing composition comprises a sealed temporary container; and a drag reducing agent and up to 20 weight percent of a dispersing fluid disposed in the sealed temporary container. The drag reducing agent comprises polyolefin particles having a particle size of about 10 to about 2,000 microns; and the dispersing fluid comprising water, an alcohol, a hydrocarbon, or a combination comprising at least one of the foregoing.

A multi-stage process for reducing the environmental contaminants in an ISO8217 compliant Feedstock Heavy Marine Fuel Oil involving a core desulfurizing process and a ultrasound treatment process as either a pre-treating step or post-treating step to the core process. The Product Heavy Marine Fuel Oil complies with ISO 8217 for residual marine fuel oils and has a sulfur level has a maximum sulfur content (ISO 14596 or ISO 8754) between the range of 0.05 mass % to 1.0 mass. A process plant for conducting the process is also disclosed.
