  • Patent number: 10920151
    Abstract: Processes for partially deoxygenating a biomass-derived pyrolysis oil to produce a fuel for a burner are disclosed. A biomass-derived pyrolysis oil stream is combined with a low recycle stream that is a portion of a deoxygenated effluent to form a heated diluted py-oil feed stream, which is contacted with a first deoxygenating catalyst in the presence of hydrogen at first hydroprocessing conditions effective to form the effluent stream. The effluent may be separated and used to provide a product fuel stream for a burner.

  • Patent number: 10703990
    Abstract: A process is disclosed for using an iron oxide and alumina catalyst with no more than more than about 55 wt % of the alumina in the diaspore phase or in the alpha phase in SHC. Alpha alumina is less effective catalyst component for slurry hydrocracking in terms of TIOR conversion. Drying procedures should avoid more than about 51 wt % of the alumina change to the alpha phase. The SHC catalyst is for converting heavy hydrocarbon feed into lighter hydrocarbon products.

  • Patent number: 10195588
    Abstract: A process and catalyst is disclosed for converting a heavy hydrocarbon feed stream into lighter hydrocarbon products using a two component catalyst. The catalyst comprises iron and molybdenum containing catalyst. Alumina may be a third catalyst component. The molybdenum is present in the heavy hydrocarbon feed stream at about 500 wppm or less and the weight ratio of iron to the molybdenum is less than 5. Much lower concentrations of expensive molybdenum can be used due to the addition of iron in the catalyst.

  • Publication number: 20170022425
    Abstract: A method for deoxygenating a biomass-derived pyrolysis oil is described. The method includes combining a biomass-derived pyrolysis oil stream with a heated low-oxygen-py-oil diluent recycle stream to form a heated diluted py-oil feed stream that has a temperature of about 150° C. or greater. The heated diluted py-oil feed stream is contacted with a first deoxygenating catalyst in a first bed of a reactor to form a low-oxygen biomass-derived pyrolysis oil. The low-oxygen biomass-derived pyrolysis oil is contacted with a hydrocracking catalyst in a second bed of the reactor to form a hydrocracked low-oxygen biomass-derived pyrolysis oil effluent. A portion of the hydrocracked low-oxygen biomass-derived pyrolysis oil effluent comprises the heated low-oxygen biomass-derived py-oil diluent recycle stream.

  • Patent number: 9527022
    Abstract: Methods and apparatus to improve hot gas filtration to reduce the liquid fuel loss caused by prolonged residence time at high temperatures are described. The improvement can be obtained by reducing the residence time at elevated temperature by reducing the temperature of the pyrolysis vapor, by reducing the volume of the pyrolysis vapor at the elevated temperature, by increasing the volumetric flow rate at constant volume of the pyrolysis vapor, or by doing a combination of these.

  • Publication number: 20160289139
    Abstract: One or more process for the production of a linear alkylbenzenes which can be used to produce surfactants. The linear hydrocarbon and the aromatic hydrocarbon are both produced from a renewable feedstock. The linear hydrocarbon may be produced by deoxygenating a natural oil and dehydrogenating the resulting hydrocarbon to provide an olefinic hydrocarbon. The aromatic hydrocarbon may be produced from the pyrolysis of a biomass and the deoxygenation of a pyrolysis oil.

  • Publication number: 20160289569
    Abstract: Processes for the production of aromatics from a pyrolysis oil. The pyrolysis oil may be obtained from a biomass by fast pyrolysis and may be filtered and upgraded to provide an aromatic rich hydrocarbon product. The aromatic rich hydrocarbon product may be passed to a separation zone to separate non-aromatic hydrocarbons from the aromatics. The remaining aromatics may be separated into aromatic product rich streams based upon the desired aromatics. Isomerization and transalkylation zones may be included to increase the yield depending on the product or desired aromatic. The non-aromatic hydrocarbons may be passed to a reformer to be converted to aromatics and hydrogen.

  • Publication number: 20150240167
    Abstract: A process and apparatus for co-processing a hydrocarbon feedstock and a renewable biomass feedstock are described. Solid particles of biomass are introduced into the riser reactor zone and mixed with catalyst. The hydrocarbon feed stock is also introduced into the riser reactor zone. The solid particles of biomass react in the presence of the catalyst and are converted into oxygenated hydrocarbons, while the hydrocarbon reacts in the presence of the catalyst to form hydrocarbon products having a lower boiling point than the feedstock.

  • Publication number: 20140318944
    Abstract: Disclosed in one embodiment is a method for the catalytic pyrolysis of a carbonaceous material that includes contacting the carbonaceous material with a plurality of catalyst particles to produce a gas phase product and a solid phase product and separating the gas phase product from the solid phase product and the plurality of catalyst particles. The method further includes partially regenerating the plurality of catalyst particles by exposing the solid phase product and the catalyst particles to a first oxidizing condition to produce an oxidized solid phase and a partially-regenerated catalyst and cooling the partially-regenerated catalyst and a non-oxidized portion of the solid phase product. Still further, the method includes further regenerating the partially-regenerated catalyst by exposing the non-oxidized portion of the solid phase product and the partially-regenerated catalyst to a second oxidizing condition.

  • Patent number: 7870870
    Abstract: This invention discloses an axial multiport rotary valve capable of accomplishing the simultaneous interconnection of a plurality of conduits in accordance with a previously determined cycle, where any conduit communicates with no more than one other conduit at any one cycle step, or valve index position. The rotary valve comprises a hollow stator element and a rotor element inside the hollow interior of the stator element which rotates with a substantially vertical axis of rotation within the stator element, the surfaces of both elements being in the form essentially of a frustum of an inverted cone. Bed-line ports in the stator and rotor have a non-circular shape with a greater dimension in the vertical plane for higher capacities than provided in the known art.
