Conversion of Biomass-Derived Oxygen-Containing Intermediates into Chemical Raw Materials with Zeolite

Article Preview

Abstract:

To establish a new production route of biomass-derived BTX and propylene, the catalytic conversion of oxygen-containing intermediates which are furfural, levulinic acid, acetic acid or butyric acid, obtained by hydrothermal reactions of bagasse or fermentation of molasses was investigated with zeolites, ZSM-5, SAPO-11 and SAPO-34. Levulinic acid and acetic acid were suitable for generating BTX with ZSM-5. On the other hand, the butyric acid was valuable for converting to chemical raw materials with ZSM-5. By using SAPO-11 as the catalyst, butyric acid converted to propylene at high yields. The yield for propylene was the maximum value 58.8C% at 723K, especially the ratio of propylene to gaseous hydrocarbon products increased up to 90.4C%.
