  • Patent number: 8993818
    Abstract: Technologies to convert biomass to liquid hydrocarbon fuels are currently being developed to decrease our carbon footprint and increase use of renewable fuels. Since sugars/sugar derivatives from biomass have high oxygen content and low hydrogen content, coke becomes an issue during zeolite upgrading to liquid hydrocarbon fuels. A self-sustainable process was designed to reduce the coke by co-feeding sugars/sugar derivatives with the paraffin products from hydrogenation of sugars/sugar derivatives. Paraffins without complete conversion result in products with less aromatics and relatively low density compared with the products directly from zeolite upgrading. Thus, the process is more economically favorable.

  • Patent number: 7947859
    Abstract: According to the present invention, when cycloolefins are produced by partially hydrogenating a monocyclic aromatic hydrocarbon with hydrogen in the presence of a ruthenium catalyst, water, and a metal sulfate, the decrease in catalytic activity and cycloolefin selectivity is suppressed by reducing the concentration of chloride ions dissolved in the water in which the catalyst is present to 300 wt ppm or less and regenerating a part or all of the catalyst for reuse. Zinc sulfate is preferably used as the metal sulfate. Further, the raw materials and catalyst to be supplied to the reaction preferably have a reduced chloride ion content. This method can suppress the decrease in long-term catalytic activity and cycloolefin selectivity. Furthermore, the catalytic activity and cycloolefin selectivity after catalyst regeneration can be maintained at a high level. As a result, cycloolefins can be efficiently produced for a long period of time.

  • 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.
