  • PROCESS TO MITIGATE THE CORROSION OF OILS/FATS
    Publication number: 20110124931
    Abstract: It has been discovered that the residence time of oils/fats in metal apparatus, particularly in the upstream of a hydrotreating unit, for example, a heat exchanger and/or a storage/feed tank, can impact significantly on corrosiveness of oils/fats in combination with and without conventional hydrocarbons. In addition, it is also found that the presence of hydrogen in the metal apparatus can also inhibit the corrosion rate of oils/fats.

  • SUGAR ALCOHOL SPLIT INJECTION CONVERSION
    Publication number: 20110087060
    Abstract: A method of hydrotreating liquefied biomass feedstock with diesel feedstock to produce alkanes is demonstrated that prevents damage to the reactor catalyst, reduces coke production, and converts nearly all of the polyols to alkanes. In order to mitigate the potential coking issue and to moderate the temperature of the catalyst bed while maintaining high conversion for sugar alcohol to hydrocarbon via a hydrotreating process, a diesel feedstock is fed over the reactor catalyst with multiple injections of polyol feedstock along the reactor.

  • HYDROTREATING CARBOHYDRATES
    Publication number: 20110046423
    Abstract: Conversion of renewable hydrocarbons to transportation fuels is required to reduce carbon emission, limit the use of fossil fuels, and develop renewable energy sources. Sorbitol, xylitol and trehelose are polyalcohols generated from the liquefaction of various sugars and carbohydrates in biomass from algae, corn, sugarcane, switchgrasses, and biological wastes. Mixtures of aqueous polyols and fuel feedstocks are catalyzed over metal catalysts to produce hexanes, pentanes, and lighter hydrocarbons. By managing the catalyst, reaction conditions and sulfur content, the octane value of the product fuel is dramatically increased.
