  • Publication number: 20130327627
    Abstract: The present invention relates generally to the thermal conversion of biomass. Processes are disclosed for converting biomass to condensable vapor intermediates such as pyrolysis oil by means of catalytic pyrolysis in a reactor comprising at least one auger, where the catalyst also comprises a heat carrier. The intermediates produced may be further processed for production of renewable hydrocarbon fuels.

  • Publication number: 20130144094
    Abstract: A single pass direct conversion of biomass derived oxygenates to longer chain hydrocarbons is described. The longer chain hydrocarbons include higher naphthene content which is quite useful in the distillate range fuels or more particularly, the jet and diesel range fuels. Naphthenes help the biomass derived hydrocarbons meet product specifications for jet and diesel while really helping cold flow properties.

  • Publication number: 20110144396
    Abstract: The present invention relates to a process for converting biomass to hydrocarbons and oxygenates. The process may include providing a biomass feedstock and de-oxygenating the biomass feedstock to form a solid-intermediate. The process may further include liquefaction of the solid intermediate, which may be carried out either by rapid heating followed by condensation or by liquefying by applying high pressure. The liquefaction of the solid intermediate may produce a mixture of hydrocarbons and oxygenates, which is generally termed as biocrude. Further, the biocrude is processed by one or more refining means for production of hydrocarbons that can be used as fuel.

  • Publication number: 20100249252
    Abstract: Disclosed are solid titanium-free Fischer-Tropsch catalysts including iron homogeneously modified with a zirconium promoter/stabilizer. The homogeneously mixed solid catalysts can be formed through co-precipitation of iron and zirconium precursors followed by calcination and reduction to form the active catalyst materials. The catalysts can optionally include additional materials such as copper, potassium, and silicon promoters.

  • Publication number: 20030012942
    Abstract: Methods for the sol-gel preparation of porous inorganic solids having highly uniform metal or metal oxide clusters embedded therein are provided. The porous solids are prepared by incorporating a metal ion-dendrimer complex into a gel and thermally decomposing the dendrimer to produce the solid. The invention further provides for novel inorganic solids exhibiting highly uniform porosity with metal or metal oxide clusters embedded therein.
