Abstract
A multi-stage process and system for converting solid particulate biomass in a riser reactor having at least two different reaction zones. A lower reaction zone is configured to optimize pyrolysis of the biomass into pyrolysis products, while an upper reaction zone is configured to efficiently crack the pyrolysis products. The relative residence times and/or temperatures of the upper and lower reaction zones can be controlled to optimize product quality and yield.
