Furfural Recovery from Kenaf Using High-Pressure CO 2 for 1,4-Butanediol Production
Abstract
This study aimed to propose a method for producing 1,4-butanediol (1,4-BDO) from inedible lignocellulosic biomass (e.g.,
kenaf). The process involved high-pressure CO 2 -catalyzed hydrolysis and dehydration to obtain furfural from kenaf and
the conversion of furfural into 1,4-BDO. In the furfural production process, the yield of furfural increased with increasing
temperature and reaction time, but a further increase in reaction time led to the formation of unwanted byproducts such as
humins. The highest furfural yield (based on kenaf) was 3.78 mg g −1 at 220 °C with a 10-min reaction time. Further, furfural
can be converted to 1,4-BDO using a bifunctional Pt/TiO 2 –ZrO 2 catalyst. The 1,4-BDO yield (based on kenaf) achieved
potentially with the Pt/TiO 2 –ZrO 2 catalytic system was 3.22 mg g −1 . The sequential conversion of kenaf biomass to valuable
chemicals showcases a sustainable approach, aligning with global eff orts toward reduced environmental impact.
