Abstract
The present disclosure relates generally to two-stage biomass pyrolysis systems configured to maximize pyrolysis vapor yield from a lignocellulosic biomass while being conducive to commercial-scale throughput of lignocellulosic biomass. The system includes a reactor first stage comprising at least one auger pyrolyzes a lignocellulosic feedstock at a temperature and residence time that produces pyrolysis vapors derived predominantly from cellulose and hemi-cellulose fractions of the feedstock. A reactor second stage is configured to partially-pyrolyzed feedstock from the reactor first stage at a higher temperature for an additional residence time to produce additional pyrolysis vapors that are predominantly derived from of lignin. Certain embodiments arrange multiple reactor first stages around a single reactor second stage.
