  • Patent number: 7744661
    Abstract: A fuel composition comprising a major amount of hydrocarbons boiling in the gasoline or diesel range and an alkylene oxide-adducted hydrocarbyl amide reaction product having from about 3 to 50 moles of alkylene oxide per mole of hydrocarbyl amide, wherein the reaction product is prepared by (a) first reacting a fatty acid or fatty acid lower alkyl ester with ammonia or a mono- or di-hydroxy hydrocarbyl amine and (b) subsequently reacting the resulting intermediate with an alkylene oxide to provide a reaction product comprising the alkylene oxide-adducted hydrocarbyl amide, a mixture of mono- and di-ester products, and amine by-products, wherein the amount of amine by-products in the reaction product is less than 7 wt %, based on the total weight of the alkylene oxide-adducted hydrocarbyl amide reaction product, and the amide:ester ratio in the reaction product is in the range of about 0.1:1 to 1.1:1.

  • Patent number: 7670392
    Abstract: An environmentally-safe, disposable, and combustible charcoal-based heat source includes a first chimney structure and a second wall structure surrounding the chimney structure. An inner chimney flue receives air for igniting and burning the charcoal-based heat source and an outer chimney flue exhausts combustion fumes from the charcoal-based heat source. A bottom wall member secures to the inner chimney flue and the outer chimney flue and forms of a combustible material to be consumed during the ignition and burning of the charcoal-based fuel. A top wall member secures to the inner chimney flue and the outer chimney flue to be consumed during the ignition of the charcoal-based fuel. A plurality of exhaust apertures are arranged within the top wall for exhausting the combustion fumes from the outer chimney flue. An ignition ring establishes a sustained ignition of sufficient duration to ignite uniformly the charcoal-based fuel. A plurality of flaps provide an initial ignition of the ignition ring.

  • Patent number: 7666235
    Abstract: A method for drying coal using microwave energy to achieve a controlled aggregate moisture content target range without starting combustion or degrading the coking qualities of the coal. Coal feed stock is first separated into fine grade coal and one or more larger grades. The fine grade coal is loaded onto a conveyor as a bed of fixed depth. The fine grade coal is conveyed continuously through a microwave-energized heating chamber for drying. The fine grade coal is dried sufficiently so that when it is combined with the larger grade coals, the moisture content of the aggregate is within a target moisture content range. By volumetrically and uniformly heating the coal, the microwave heating chamber boils away the water without heating the coal itself above about 90° C. In this way, the coal does not combust or oxidize, and its coking qualities are retained.
