Selective Preparation of Light Olefins from Cellulose-Derived Fermentation Intermediates
Directional synthesis of bio-based light olefins has great significance for pro-moting sustainable development of chemical industry.Present work proves that light olefins can be selectively pre-pared from the cellulose-derived acetone-butanol-ethanol.This transformation has been achieved by coupling cellulose fermentation and acetone-butanol-ethanol catalytic dehydration over the Ce@SAPO-34 catalyst.The active sites and reusability of the catalyst were in-vestigated.High acetone-butanol-ethanol conversion(91.9％)and high olefin selectivity(86.1％)are achieved.Based on the study of the individual components in acetone-butanol-ethanol,the reaction pathways are put forward.
