Selective Pyrolysis Behaviors of Willow Catalyzed via Phosphoric Acid

Abstract:

Willow is an abundant plant in many countries all over the world. It has an extremely rapid growing rate, and it can be considered as a sustainable raw material wood resource. In this study, H₃PO₄ of catalyzed willow pyrolysis was investigated by means of CP-GC-MS. Moreover pyrolysis products such as furfural, levoglucosenone,levoglucosan and phenolic compounds was ananlyzed. The results indicate that H₃PO₄ shows increased selectivity towards sugar and furan compounds at the expense of acetic acid and phenolic compounds. The biomass treatment with H₃PO₄ enhances dehydration and decarbonylation of levoglucosan resulting in more furfural and levoglucosenone, promoting the lignin to form carbon rather than phenolic compounds. and inhibit acetic acid formation.. The content of the major sugar compounds reached 50% in the prensence of catalyst. The content of the major furan compounds enhanced, mainly furfural.
