  • Publication number: 20150052802
    Abstract: Biological source oils, including, but not limited to, algae oil, stabilize the presence of asphaltenes in petroleum feedstocks, such as crude oil, to help avoid or prevent problematic issues caused by the asphaltenes, such as sludges, plugging, deposits, fouling and/or corrosion in the production, transferring and processing of the petroleum feedstocks. Chemical additives such as phenol-based resins, and reaction products or combinations of long chain alpha-olefins and/or small chain aldehydes and/or long chain alkyl phenate sulfides and/or metal oxide-based colloidal hydrocarbon-based nanodispersions, may also stabilize the presence of asphaltenes in petroleum feedstocks. By “stabilizing” is meant keeping the asphaltenes in solution in the petroleum feedstocks.

    Abstract: This invention provides low sulfur fuels, particularly low sulfur bunker fuels, comprising hydroprocessed pyrolysis oil. The hydroprocessed pyrolysis oil can be produced using a catalyst suited to processing pyrolysis oils that may be relatively high in water content and under relatively low severity conditions to limit water formation, while making the hydroprocessed pyrolysis oil more stable than prior to hydroprocessing. The pyrolysis oil can be converted to a more stable hydroprocessed product, e.g., by converting at least a majority of the aldehydes, ketones, and/or carboxylic acids in the pyrolysis oil to more highly stable compounds, such as alcohols. The hydroprocessed product can be particularly suited as a blend component for producing a variety of reduced sulfur fuels.

    Abstract: A pellet manufactured from a porous combustible material which is infused with a combustible liquid accelerant. The pellet is preferably made from wood shavings, crushed cocoa shells or coffee grounds that are compressed together. The compressed materials are then soaked in a liquid accelerant, such as a petroleum product, or sprayed with a petroleum product. This results in a pellet that has only an outermost layer that includes the accelerant or the entire pellet is saturated with the accelerant. The pellets are then poured over the wood or briquettes that are to be burned and they tend to filter into the spaces between the wood logs or briquettes. The accelerant is volatile and consequently when a flame is applied to one or more pellets they ignite quickly and the flames spread rapidly from one pellet to another and thereby to the wood logs or briquettes that they surround.

    Abstract: In the present invention, a solution of synthetic anionic surface active agents is at first prepared by mixing and homogenizing sodium polyoxyethylenealkylether sulfate and sodium alpha-olefin sulfonate (both are anionic surface active agents). Distillated water is added to this solution with mixing such that the mixture becomes a mousse-like emulsion that homogeneously contains a sufficient amount of air bubbles. A condensed emulsion fuel material is then produced by adding petroleum liquid fuel to the mousse-like emulsion with mixing. The concentrated emulsion fuel material and an emulsion fuel has an excellent chemical stability and does not separate to water and oil layers even after a long term storage. In addition, as it can be combusted at a high temperature boiler without requiring so much air, the emission of both soot (dust) and NOx are simultaneously reduced.

  • Patent number: 5336277
    Abstract: The resistance of in-tank fuel pump copper commutators to become excessively worn by exposure to petroleum fuels containing at least 10 mg/liter of elemental sulfur is substantially increased by the addition of at least about 5 mg/liter of an organomercaptan, compound and at least about 25 mg/liter of a copper metal deactivator capable of forming a sulfur - resistant barrier coating on the copper commutator, to produce a novel fuel composition.

  • Patent number: 5154844
    Abstract: A product formed by heating (A) a mixture of a carboxylic acid ester and a fatty acid oxyalkylated amine derivative selected from fatty acid amides, fatty acid esters, fatty acid ester-amides of such oxyalkylated amine, and mixtures thereof with (B) sulfur or a sulfur source at an elevated temperature at which sulfurization occurs. Such products are effective as oil additives in inhibiting excessive wear and sludge formation. And they possess excellent compatibility with oils of lubricating viscosity, such as mineral oils used as crankcase lubricating oil base stocks.
