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-crudeoil 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 C=O of organic acid is more difficult than that of aldehydes and ketones. HUSY/gamma-Al2O3 and REY/gamma-Al2O3 catalysts exhibited better deoxygenating activities while HZSM-5/gamma-Al2O3 catalyst exhibited preferred selectivities for production of iso-alkanes and aromatics. Finally, possible mechanisms of biomass catalytic pyrolysis are discussed as well. (c) 2007 Ran Zhong Yao. Published by Elsevier B.V. on behalf of Chinese Chemical Society. All rights reserved.
