Research output: Patent


The present disclosure relates to a method that includes pyrolyzing a biomass to produce a pyrolysis oil and upgrading the pyrolysis oil to yield a first upgraded pyrolysis oil, where the pyrolysis oil is in at least one of a liquid phase and/or a vapor phase, the pyrolyzing is performed in a pyrolysis reactor at a first temperature between C. and C., the biomass has a residence time of less than five seconds in the pyrolysis reactor, the upgrading is performed in a fluidized bed reactor, and the upgrading is catalyzed using a zeolite.
