Abstract
Aspects of the present invention relate to methods, systems, and compositions for preparing a solid biomass for fast pyrolysis. The method includes contacting the solid biomass with an inorganic material present in an effective amount for increasing fast pyrolysis yield of an organic liquid product (e.g., bio-oil). In various embodiments, the inorganic material is selected from the group consisting of aluminum sulfate, aluminum nitrate, aluminum chloride, aluminum hydroxide, ammonium hydroxide, magnesium hydroxide, potassium hydroxide, and combinations thereof.
