Production of furfural from xylose and corn stover catalyzed by a novel porous carbon solid acid in γ-valerolactone

High yields of furfural (>90 %) were achieved from xylose dehydration in a sustainable solvent system composed of γ-valerolactone (GVL), a biomass derived solvent, and water. It is identified that high reaction temperatures (e.g., 498 K) are required to achieve high furfural yield. Additionally, it is shown that the furfural yield at these temperatures is independent of the initial xylose concentration, and high furfural yield is obtained for industrially relevant xylose concentrations (10 wt %). A reaction kinetics model is developed to describe the experimental data obtained with solvent system composed of 80 wt % GVL and 20 wt % water across the range of reaction conditions studied (473-523 K, 1-10 mm acid catalyst, 66-660 mm xylose concentration). The kinetic model demonstrates that furfural loss owing to bimolecular condensation of xylose and furfural is minimized at elevated temperature, whereas carbon loss owing to xylose degradation increases with increasing temperature. Accordingly, the optimal temperature range for xylose dehydration to furfural in the GVL/H O solvent system is identified to be from 480 to 500 K. Under these reaction conditions, furfural yield of 93 % is achieved at 97 % xylan conversion from lignocellulosic biomass (maple wood).

“…The yields obtained were 79 and 61%, respectively, for residence time varying between 30 and 100 min. Recently, a carbonized resorcinol-formaldehyde resin and sulfonated was also tried as a catalyst (Zhu et al, 2017 ). The material was found efficient for furfural production from D-xylose and corn stover in GVL.…”

Biobased production of furfural has been known for decades. Nevertheless, bioeconomy and circular economy concepts is much more recent and has motivated a regain of interest of dedicated research to improve production modes and expand potential uses. Accordingly, this review paper aims essentially at outlining recent breakthroughs obtained in the field of furfural production from sugars and polysaccharides feedstocks. The review discusses advances obtained in major production pathways recently explored splitting in the following categories: (i) non-catalytic routes like use of critical solvents or hot water pretreatment, (ii) use of various homogeneous catalysts like mineral or organic acids, metal salts or ionic liquids, (iii) feedstock dehydration making use of various solid acid catalysts; (iv) feedstock dehydration making use of supported catalysts, (v) other heterogeneous catalytic routes. The paper also briefly overviews current understanding of furfural chemical synthesis and its underpinning mechanism as well as safety issues pertaining to the substance. Eventually, some remaining research topics are put in perspective for further optimization of biobased furfural production.

“…Compared to mineral acid H 2 SO 4 (Brønsted acid, pH=1) and solid acid catalyst PTSA‐POM (Brønsted acid), the furfural yield by FePO 4 catalytic decreased by 6.7% and 1.9%, respectively. In attention, the furfural yield under FePO 4 catalyst was higher than most of mineral acid (Brønsted acid, H 3 PO 4 , HCl, H 2 SO 4 with pH=2), metal chlorate FeCl 3 ⋅6H 2 O (Lewis acid), solid acid catalyst S‐RFC (Brønsted acid) and SO 4 2− /SnO 2 − MMT (Brønsted/Lewis acid) . Compared to the liquid acid catalyst (such as mineral acid and metal chlorate), the FePO 4 catalyst with both contained Brønsted/Lewis acid sites, provided an effective catalytic activity for furfural production.…”

Furfural has been identified as an attractive platform chemical for production of valuable bio‐based chemicals and bio‐fuels. Therefore, to exploit a new catalyst which directly synthesized furfural from biomass was meaningful. In this work, FePO4⋅2H2O was novelty applied in H2O/THF solvent system to produce furfural from bamboo meal. The influence of catalyst type, solvent type, catalyst dosage, reaction temperature and times on furfural production was comparatively evaluated. The results indicated that the FePO4 catalyst displayed an excellent catalytic activity over mineral acids, metal chlorate and solid acids, achieving the highest furfural yield of 90.5% (from d‐xylose) and 83.1 mol % (from bamboo meal) at 170 °C (60 min) and 180 °C (60 min), respectively. Moreover, characterization indicated that FePO4 can recrystallize after the reaction, which provided a convenience for the catalyst recovery. Considering the excellent catalytic activity and recovering characteristic of FePO4 catalyst, systematical research of this new technique was required before the process could be considered as an industrial scale.
