This study successfully achieved the efficient co-production of xylooligosaccharides, furfural, and reducing sugars from yellow bamboo using a novel solid acid catalyst, and the good performance of the catalyst was confirmed through stability experiments.
The research on the efficient use of biomass to produce chemical products has received extensive attention. In this work, a novel heterogeneous biocarbon-based heterogeneous catalyst AT-Sn-YB was prepared using yellow bamboo (YB) as a carrier, and its physical properties were proved to be good by various characterization and stability experiments. In the.-valerolactone/water (3:1, v/v) medium containing 100 mM CuCl2, the use of ATSn-YB (3.6 wt%) under 170 degrees C for 20 min was applied to catalyze YB into furfural (80.3% yield), accompanied with 2.8 g/L xylooligosaccharides. The YB solid residue obtained from treatment was efficiently saccharified to reducing sugars (17.2 g/L). Accordingly, comprehensive understanding of efficiently co-producing xylooligosaccharides, furfural and reducing sugars from YB was demonstrated via the pretreatment with biochar-based catalyst. This study innovatively used a new type of solid acid to complete the efficient co-production of chemical products, and realized the value-added utilization of yellow bamboo.
