Abstract
Methods of separating and purifying products from the catalytic fast pyrolysis of biomass are described. In a preferred method, a portion of the products from a pyrolysis reactor are recovered and purified using a hydrotreating step that reduces the content of sulfur, nitrogen, and oxygen components, and hydrogenates olefins to produce aromatic products that meet commercial quality specifications.
