Abstract:
Biogases such as natural gas and other gases capable of being biologically derived by digestion of organic matter are converted to a clean-burning hydrocarbon liquid fuel in a process wherein a biogas is fed to a reaction vessel where the biogas contacts a liquid petroleum fraction and a transition metal catalyst immersed in the liquid, vaporized product gas is drawn from a vapor space above the liquid level, condensed, and fed to a product vessel where condensate is separated from uncondensed gas and drawn off as the liquid product fuel. Uncondensed gas can be recycled to the reaction vessel.
Abstract:
A new and useful way of producing a used oil fuel mixture for a compression ignition engine is provided. A mass of used oil from which water has been substantially removed, is initially filtered, e.g. to remove particles greater than a predetermined size. The used oil is then centrifuged, under predetermined conditions to remove any remaining water and to remove particles to a predetermined size level. The drained, filtered and centrifuged used oil is then mixed with fuel (e.g. diesel fuel) in a predetermined ratio, to form a used oil fuel mixture and optionally adding an additive (e.g. a diesel fuel additive) to the used oil fuel mixture. Then, the used oil fuel mixture is centrifuged to promote mixing, and the centrifuged used oil fuel mixture is then pumped through one or more final filtering stages, to produce the used oil fuel mixture that is useful with compression ignition engines.
Abstract:
A method and apparatus for the removal of at least part of the impurities of bio-diesel fuel, said impurities typically arising from production said purification involving exposure of the ‘raw’ bio-diesel to one or more fragments of plant material. The purification process can be a batch or continuous process.

The present invention provides a gas oil composition for use in a diesel engine with a geometric compression ratio of greater than 16, equipped with a supercharger and an EGR, containing an FT synthetic base oil and having a sulfur content of 5 ppm by mass or less, an oxygen content of 100 ppm by mass or less, a bulk modulus of 1250 MPa or greater and 1450 MPa or less, a saybolt color of +22 or greater, a lubricity of 400 μm or less, an initial boiling point of 140° C. or higher and an end point of 380° C. or lower in distillation characteristics, and the following characteristics (1) to (3) in each fraction range wherein: (1) the cetane number in a fraction range of lower than 200° C. is 20 or greater and less than 40; (2) the cetane number in a fraction range of 200° C. or higher and lower than 280° C. is 30 or greater and less than 60; and (3) the cetane number in a fraction range of 280° C. or higher is 50 or greater. The gas oil composition is used in a summer or winter season, suitable for both diesel combustion and homogeneous charge compression ignition combustion.
Abstract:
Methods for fractional catalytic pyrolysis which allow for conversion of biomass into a slate of desired products without the need for post-pyrolysis separation are described. The methods involve use of a fluid catalytic bed which is maintained at a suitable pyrolysis temperature. Biomass is added to the catalytic bed, preferably while entrained in a non-reactive gas such as nitrogen, causing the biomass to become pyrolyzed and forming the desired products in vapor and gas forms, allowing the desired products to be easily separated.
Abstract:
The present invention provides a solid stick composition comprising a thermosetting resin and a grease. Optionally, the solid stick composition may comprise a lubricant, a friction modifier, a thermoplastic plasticizer or a combination thereof. The solid stick compositions may be used for application between two metal surfaces in sliding and rolling-sliding contact such as steel wheel-rail systems including mass transit and freight systems. A method of reducing energy consumption, or controlling friction between a metal surface and a second metal surface by applying the solid stick composition to one or more than one of the metal surfaces, is also provided.
Abstract:
The present invention is generally directed to novel fuel compositions and to methods (i.e., processes) for enhancing the combustion efficiency and/or other properties of diesel fuels, particularly wherein such diesel fuels are, or comprise, biodiesel, such biodiesel typically having poorer low-temperature properties than traditional (petroleum) diesel. Generally, such fuel compositions are provided by the creation and inclusion of a quantity of one or more epoxy-ester species, such species serving as combustion improvers for the fuel composition of which they are part.
Abstract:
Liquefied petroleum coke (LPC) comprises diesel engine fuel grade petroleum coke that is produced by subjecting crude oil refinery feedstock to de-salting, coking, micronization, de-ashing, and slurrification processes to reduce impurities such as metallic components and make the LPC suitable for use in internal combustion engines, such as diesel engine systems.
Abstract:
Methods for recovery of concentrates of lubricating compounds and biologically active compounds from vegetable and animal oils, fats and greases that allow separation of triglycerides, from components with higher lubricity or biological activity or enrichment protocols that increase the concentration of high lubricity or biologically active compounds in the triglyceride. The triglycerides are transesterified with a lower alcohol to produce alkyl esters. Following the conversion process the esters are separated from high molecular weight high lubricity compounds and biologically active compounds by distillation. The esters have some lubricity and may be sold as pollution reducing fuel components. The high boiling point compounds that are the residues of distillation, however, can either contribute significant lubricity and may be used widely in lubricant applications or added to petroleum fuels to decrease friction or the biologically active components may be used in nutritional, cosmetic and therapeutic applications. Therapeutic applications include use in human diets to lower cholesterol.
