Abstract

To establish a new production route of biomass-derived propylene, the catalytic conversion of butyric acid which can be obtained by the acid fermentation of molasses was investigated with zeolites, ZSM-5, SAPO-11and SAPO-34. Using SAPO-11 as the catalyst, butyric acid is converted to propylene at high yields. The yield for propylene was at the maximum value of 58.8 C% at 723 K, with the ratio of propylene to gaseous hydrocarbon products increased up to 90.4 C%.
