| 20120035404 | HYDROCARBONS FROM PYROLYSIS OIL - The present invention relates to a process for converting pyrolysis oil obtained by pyrolysis of biomass into fuel range hydrocarbon by alcoholysis of pyrolysis oil with subsequent hydrotreatment. The current invention provides straightforward methodology to prepare upgradable pyrolysis oil via alcoholysis. The invention uses hydrotreating technology for oxygen removal and hydrocarbon production. The resulting hydrocarbon products are 100% fungible with conventional transportation fuels. | 02-09-2012 |

| 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 |

| 20120108860 | PROCESS FOR PRODUCING HIGH QUALITY PYROLYSIS OIL FROM BIOMASS - This invention relates to a process to utilize a torrefaction pretreatment step for biomass pyrolysis process. This pretreatment improves the quality of the pyrolysis oil by reducing acidity. The inventive process shows that as a pretreatment to pyrolysis, resulting pyrolysis oil obtained from torrefied biomass has approximately 25% lower acetic acid than that from untorrefied biomass pyrolysis oil. | 05-03-2012 |

| 20090078262 | FILTERING FACE-PIECE RESPIRATOR SUPPORT STRUCTURE THAT HAS LIVING HINGES - A filtering face-piece respirator | 03-26-2009 |
| 20090078268 | BUCKLE HAVING A FLEXURAL STRAP ATTACHMENT MEMBER AND RESPIRATOR USING SUCH BUCKLE - Respirator and buckle having a flexural member allowing the buckle to move in three dimensions, potentially improving user comfort, the effectiveness of the respirator, and allowing for more precise adjustments to be made to the fit of the respirator on the user. The flexural member may be a three dimensional living hinge. By lifting on the buckle, the straps that secure the respirator to the user are released and the ability of the buckle to move in three dimensions tends to increase the situations in which the adjustment may occur. Various types of three dimensional living hinges may be utilized, including a cylindrical hinge and a serpentine hinge. | 03-26-2009 |
| 20090090364 | FILTERING FACE-PIECE RESPIRATOR HAVING NOSE CLIP MOLDED INTO THE MASK BODY - A filtering face-piece respirator | 04-09-2009 |
| 20090193628 | BUCKLE AND RESPIRATOR USING SUCH BUCKLE, HAVING A DEFORMABLE CINCH BAR, AND METHOD - Buckle and respirators having such buckles. The buckle has a movable cinch bar allowing a strap to be inserted into and be secured by the buckle by opening the cinch bar and inserting the strap. The cinch bar then returns to a closed position and supports the strap over the cinch bar. The cinch bar may be deformable through the use of a living hinge connecting the cinch bar to the body of the buckle. The cinch bar may be split into two members, each being deformably coupled to the buckle body, perhaps with living hinges. | 08-06-2009 |
