“…A mesoporous Nb 2 O 5 acid catalyst gave over 90% conversion and 50% selectivity of xylose to furfural without leaching Nb 2 O 5 ; however, commercial Nb 2 O 5 exhibited low activity . This result indicated that the pore size of the catalyst has an important effect on the product selectivity and should be in the range of 3–5 nm, as reported in our previous study . The accessibility and availability of acidic sites are known to affect the reaction rate.…”

“…The increase in the furfural selectivity and yield resulted from the increase in the number of strong acid sites (sulfonic acid). Moreover, the pore size (3.8 nm) was suited to the selective production of furfural . Therefore, the number of acid site, acid strength, and accessibility were the key factors on catalytic activity in xylose dehydration .…”

“…The dehydration of xylose was carried out in an autoclave reactor (Amar Equipments, India, 400.0 mL) containing a mixture of xylose solution (0.50 g of xylose dissolved in 12.5 mL of DI water), 12.5 mL of toluene, and catalyst . The reactor was heated to the desired reaction temperature (120, 140, 155, and 170°C) at a stirring rate of 450 rpm for a specific reaction time (1–3 h).…”

A sulfonated carbon material was developed and investigated as an environmentally benign catalyst for furfural production. The sulfonic acid functionality was introduced by sequential hydrothermal carbonization and sulfonation of xylose. The morphology and textural properties were examined by scanning electron microscopy and N2 sorption measurements, respectively. The presence of sulfonic acid on the surface was proven by both Fourier transform infrared spectroscopy and X‐ray photoelectron spectroscopy analysis. Meanwhile, the acid properties were studied using an NH3‐TPD profile. Two different sulfonated carbons that was activated with KOH before sulfonation and one that was compared. The KOH‐activated sulfonated carbon contained both a porous structure and a high sulfonic acid content that improved the furfural yield and selectivity by more than 50% compared to the nonactivated sulfonated carbon. The reusability of the catalyst was investigated by monitoring the furfural selectivity over several reaction cycles, and after the 3rd cycle, a reduction in the selectivity from 72 to 30% was observed. However, the acid‐functionalized carbon could still be useful for furfural production due to its low environmental impact in both the preparation and disposal steps. © 2017 American Institute of Chemical Engineers Environ Prog, 37: 1455–1461, 2018

Recent Advances in the Catalytic Production of Platform Chemicals from Holocellulosic Biomass

This Review discusses novel catalytic pathways of lignocellulosic biomass to value‐added chemicals including biomass‐derived sugar alcohols, organic acids, furans and biohydrocarbons. These production approaches are undertaken by biological, chemical and thermochemical transformations or a combination of them. Nevertheless, the majority of research in this area is focused on the design of heterogeneous catalysts to convert value‐added products from holocellulosic biomass. Biorefineries represent the peak of biomass processes in order to produce valuable chemicals and liquid fuels avoiding the utilization of corroding and toxic elements. The aim of the present Review is to offer the readers a broad overview of recent holocellulosic‐based chemical and fuels production technologies via heterogeneous catalysis. There is also an overview of the economic aspects to efficiently produce these platform chemicals at industrial scale. To summarize this Review, an outlook and conclusions of the reported processes to date is provided.

“…Under the circumstance, multifarious zeolites were explored and gained more and more popularity in biomass conversion including SBA-15, 26 functionalized MCM-41 (ref. 27) and Sn-MMT 28 as well as SAPO-34. 29 But hydrothermal stability of zeolites still needs to be improved.…”

A resorcinol-formaldehyde resin carbon (RFC) catalyst with a well-developed, ordered, mesoporous framework was prepared using a soft template method at room temperature. The carbon was sulfonated in water using sulfanilic acid under mild atmospheric conditions. The sulfonated RFC (S-RFC) was characterized by N 2 adsorption-desorption, elemental analysis, TEM, XPS, and FT-IR. It was determined that S-RFC is an efficient solid acid catalyst for furfural production from xylose and corn stover in gvalerolactone (GVL). The effects of reaction time, reaction temperature, catalyst loading, substrate dosage and water concentration were investigated. 80% furfural yield and 100% xylose conversion were obtained from xylose at 170 C in 15 min with 0.5 g catalyst. Comparatively, 68.6% furfural yield was achieved from corn stover at 200 C in 100 min when using 0.6 g catalyst. Since there was no discernable decrease in furfural yield after multiple conversions utilizing the same catalyst, the recyclability of the catalyst is considered good.
