Patent number: 9816040Abstract: The present disclosure relates generally to novel biomass pyrolysis processes and systems that decrease entrainment of char and other contaminants with the pyrolysis vapors as a direct consequence of the biomass feedstock comprising particles that are larger than a defined minimum diameter. The biomass feedstock may optionally be compressed to form feedstock pellets that are larger than a defined minimum diameter.Type: GrantFiled: September 9, 2013Date of Patent: November 14, 2017Assignee: Phillips 66 CompanyInventors: Daren E.

Patent number: 9028676Abstract: 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.Type: GrantFiled: July 31, 2014Date of Patent: May 12, 2015Assignee: Phillips 66 CompanyInventors: Kening Gong, Alexandru Platon, Terry S. Cantu, Daren E. Daugaard

Patent number: 8992736Abstract: 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 sequential steps of rapid quenching and electrostatic precipitation comprising injecting a coolant comprising at least one of nitrogen, a noble gas and mixtures thereof into a hot pyrolysis vapor to selectively condense a first fraction of components from the hot pyrolysis vapor at a first predetermined temperature which is then collected by electrostatic precipitation in a first electrostatic precipitator at about the first predetermined temperature, where a wall temperature of the first electrostatic precipitator is maintained slightly higher than the first predetermined temperature. The sequential steps of coolant injection and collection are repeated at progressively cooler temperatures in order to selectively collect one or more fractions of the hot mixture.Type: GrantFiled: May 24, 2011Date of Patent: March 31, 2015Assignees: Iowa State University Research Foundation, Inc., Phillips 66 CompanyInventors: Daren E. Daugaard, Samuel T. Jones, Dustin L. Dalluge, Robert C. Brown

Patent number: 8936654Abstract: 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.Type: GrantFiled: December 21, 2011Date of Patent: January 20, 2015Assignee: Phillips 66 CompanyInventors: Alexandru Platon, Ronald E. Brown, Daren E. Daugaard

Patent number: 8846992Abstract: A process for converting biomass to hydrocarbons and oxygenates that 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.Type: GrantFiled: December 1, 2010Date of Patent: September 30, 2014Assignee: Philips 66 CompanyInventors: Edgar Lotero, Alexandru Platon, Daren E. Daugaard, Kristi Fjare

Publication number: 20130327626Abstract: The present invention relates generally to the thermal conversion of biomass. Processes are disclosed for converting algal biomass to condensable vapor intermediates such as pyrolysis oil by means of pyrolysis in a reactor comprising at least one auger. The intermediates may be further processed for production of renewable hydrocarbon fuels. The disclosed processes assist in preventing premature devolatization of algal biomass during pyrolysis, thereby increasing efficiency and commercial feasibility.Type: ApplicationFiled: June 10, 2013Publication date: December 12, 2013Inventors: Daren E.
