  • Patent number: 9738909
    Abstract: A method is provided to transform biomass. Non-food biomass is preprocessed. Then, fermentation is processed to generate ethanol. Ethanol is dehydrated through a catalyst to generate ethylene. After the dehydration, oligomerization is processed with a catalyst to transform ethylene into olefins having 6˜20 carbon atoms (C6˜C20). The olefins are hydrotreated into alkanes. Thus, C6˜C20 hydrocarbons having long carbon chains are formed. The hydrocarbons having 6˜10 carbon atoms can be used as gasoline; those having 8˜16 carbon atoms, jet fuel; and those having 16˜20 carbon atoms, diesel. On generating ethanol, byproducts of lignin may be generated. The byproducts can be processed through depolymerization/deoxygenation to generate aromatic hydrocarbons or can be gasified to generate methanol or dimethyl ether. By further processing dehydration, aromatic hydrocarbons are generated to be mixed into gasoline, jet fuel or diesel. Or, the lignin byproducts are gasified to generate syngas.

    Abstract: A process for upgrading pyrolysis oil that includes heating pyrolysis oil in the absence of added catalyst at 100° C. to 200° C. temperature and 50 bar to 250 bar pressure, and heating the product of the first heating in the absence of added catalyst at 200° C. to 400° C. temperature and 50 bar to 250 bar pressure. Also, the product obtained by this process and the use of treated pyrolysis oil. Further, methods where the treated pyrolysis oil is fed to a power plant for producing electricity; is burned in a boiler for producing heating oil and/or is used as transportation fuel or as a blending component in transportation fuel.

  • Patent number: 8957268
    Abstract: Methods are provided for refining natural oil feedstocks. The methods comprise reacting the feedstock in the presence of a metathesis catalyst under conditions sufficient to form a metathesized product comprising olefins and esters. In certain embodiments, the methods further comprise separating the olefins from the esters in the metathesized product. In certain embodiments, the methods further comprise hydrogenating the olefins under conditions sufficient to form a fuel composition. In certain embodiments, the methods further comprise transesterifying the esters in the presence of an alcohol to form a transesterified product.
