20110144396 | PROCESS FOR CONVERTING BIOMASS TO HYDROCARBONS AND OXYGENATES - 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. | 06-16-2011 |
20110182788 | CATALYTIC MOVING BED FILTER - The present invention relates generally to a method for removing contaminants from a fluid stream and chemically upgrading the stream at the same time. More particularly, the invention relates to a catalytic moving bed filter for removing contaminants from a gas or vapor stream and to compositions comprising both moving bed filter materials and one or more catalysts intimately admixed therewith. | 07-28-2011 |
20110315537 | SELECTIVE TEMPERATURE QUENCH AND ELECTROSTATIC RECOVERY OF BIO-OIL FRACTIONS - A process for quenching, separating and collecting targeted components of a hot pyrolysis product stream from the pyrolysis of biomass is provided. The process utilizes rapid quenching and electrostatic precipitation at a predetermined temperature in order to selectively collect one or more fractions of the hot mixture. | 12-29-2011 |
20120160741 | INTEGRATED FCC BIOMASS PYROLYSIS/UPGRADING - Integrating a biomass pyrolysis and upgrading process into a fluid catalytic cracking unit. The process uses conventional FCC feed and a mixture of a solvent and biomass to produce upgraded fuel products. A slurry stream composed of solid biomass particles and a solvent is fed into an FCC riser through a slurry pump to achieve biomass pyrolysis and in situ pyrolysis oil upgrading. The catalytic cracking of the conventional petroleum feed also occurs in the riser. | 06-28-2012 |
20120167452 | ABSORPTION AND QUENCH METHOD FOR BIOMASS PYROLYSIS PRODUCT - A biomass pyrolysis product is quenched by direct cooling with a cold quench fluid and initial product separation is performed based on boiling point and solubility in the quench fluid. A properly chosen quench fluid may act as a selective solvent, thus providing dilution of unstable precursors of pyrolytic lignin or other heavy by-products, and/or separation of certain undesirable pyrolysis oil components such as water and light acids. | 07-05-2012 |
20130014431 | ADVANCED, BIOMASS-DERIVED, LOW-SULFUR BUNKER FUELS - A fuel composition and the process of making the fuel composition are described. More specifically, a novel biomass derived low sulfur bunker fuels composition and the method of making thereof. Embodiment of the invention discloses a novel low sulfur bunker fuels composition derived from blending various bio-oil with other heavy residual fuel oils and distillates where final sulfur content and carbon intensity is controlled by the ratio of bio-oil to other heavy residual fuel oils and distillates. Embodiment of the invention also discloses a process of making a novel biomass derived low sulfur bunker fuels by blending various bio-oil with other heavy residual fuel oils and distillates. | 01-17-2013 |
20130327626 | CATALYTIC PYROLYSIS OF BIOMASS IN AN AUGER REACTOR - The present invention relates generally to the thermal conversion of biomass.
