Abstract:
Commercially, furfural is produced from pentosan-rich biomass using mineral acids, such as H2SO4 and H3PO4, as a homogeneous catalyst. In this study, environmentally friendly Al2(SO4)3 was used for the conversion of hemicelluloses to furfural by hydrothermal pretreatment in a continuous steam flow reactor. Hemp (Cannabis sativa L.) shives were used as a feedstock due to the high content of hemicelluloses (30.2 wt%) – and the use of hemp shives has not been investigated for furfural production to date. In this study, the variable treatment parameters were residence time (10-90 min), temperature (140-180ºC) and the amount of the catalyst (3-7 wt%). The highest obtained yield of furfural was 71.1% of the theoretical yield.
