Patent number: 10174258Abstract: The present disclosure relates generally to a two-stage biomass pyrolysis processes that maximize pyrolysis vapor yield from a lignocellulosic biomass while being conducive to commercial-scale throughput of biomass. A lignocellulosic feedstock is first pyrolyzed in a reactor first stage comprising at least one auger at a temperature and residence time that produces pyrolysis vapors derived predominantly from cellulose and hemi-cellulose fractions of the feedstock. Partially-pyrolyzed feedstock from the reactor first stage is then pyrolyzed in a reactor second stage at a higher temperature for an additional residence time to produce additional pyrolysis vapors that are predominantly derived from lignin. Certain embodiments arrange multiple reactor first stages around a single reactor second stage.Type: GrantFiled: February 17, 2017Date of Patent: January 8, 2019Assignee: Phillips 66 CompanyInventors: Dustin L. Dalluge, Steven E. Lusk, Samuel T. Jones, Johnathan T. Gorke

Patent number: 9611439Abstract: The present invention relates to a method of fractionating bio-oil vapors which involves providing bio-oil vapors comprising bio-oil constituents. The bio-oil vapors are cooled in a first stage which comprises a condenser having passages for the bio-oil separated by a heat conducting wall from passages for a coolant. The coolant in the condenser of the first stage is maintained at a substantially constant temperature, set at a temperature in the range of 75 to 100° C., to condense a first liquid fraction of liquefied bio-oil constituents in the condenser of the first stage. The first liquid fraction of liquified bio-oil constituents from the condenser in the first stage is collected. Also disclosed are steps for subsequently recovering further liquid fractions of liquefied bio-oil constituents. Particular compositions of bio-oil condensation products are also described.Type: GrantFiled: May 29, 2013Date of Patent: April 4, 2017Assignee: Iowa State University Research Foundation, Inc.Inventors: Robert C. Brown, Samuel T. Jones, Anthony Pollard

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.
