Study on biomass catalytic pyrolysis for production of bio-gasoline by on-line FTIR

The pyrolysis of biomass is a promising way for production of bio-gasoline if the stability and quality problems of the bio-crude-oil can be solved by catalytic cracking and reforming. In this paper, an on-line infrared spectrum was used to study the characteristics of catalytic pyrolysis with the following preliminary results. The removal of CO of organic acid is more difficult than that of aldehydes and ketones. HUSY/γ-Al₂O₃ and REY/γ-Al₂O₃ catalysts exhibited better deoxygenating activities while HZSM-5/γ-Al₂O₃ catalyst exhibited preferred selectivities for production of iso-alkanes and aromatics. Finally, possible mechanisms of biomass catalytic pyrolysis are discussed as well.
