“…The relative proportions of the various saccharides depend on the severity of the operational conditions. Pentoses and higher saccharides made up of pentoses can be converted to furfural (F) by hydrolysis/dehydration reactions (Sánchez et al 2013;Nakagame et al 2014;Baktash et al 2015;García-Domínguez et al 2015;Koch and Kindler 2015;Liu et al 2015). F, a commercial product with a favourable market forecast (Dalin Yebo 2015), was considered as one of the top 12 platform chemicals derived from biomass in a report from the U.S. Department of Energy (Werpy et al 2004), which was updated 6 years later (Bozell and Petersen, 2010;De Jong et al 2012).…”

Birch samples were subjected to non-isothermal autohydrolysis to obtain a solution of hemicellulosic saccharides and a solid phase mainly made up of cellulose and lignin. Based on kinetic modeling, operational conditions were identified which give rise to soluble saccharides and furfural derived from xylan in a yield of 80.5%. The soluble mixture was supplemented with 1% sulfuric acid and heated (directly or in the presence of methyl isobutyl ketone, MIBK) for furfural production. MIBK is used as an extraction agent to limit furfural consumption by side reactions. Operating in single phase at 170°C, up to 44.8% of the potential substrates were converted into furfural. In experiments performed in biphasic media, the effects of MIBK were assessed by empirical modeling and about 75% of the potential substrates were converted under selected conditions.

“…Hemicelluloses in the liquor were concentrated through membrane separation and converted to furfural using reactors in monophasic and biphasic systems, proving the feasibility of the process. Baktashet (2015) [41] also used the pre-hydrolysis liquor from kraft process as feedstock for furfural production. Besides the membrane separation and concentration also accomplished by Kaur (2015) [40], Baktashet (2015) [41] also employed adsorption in activated carbon and treatment with ionic exchange resins as pretreatments to increase furfural production yield, contribute to lignin removal, facilitate the process and minimize side reaction.…”

The use of renewable sources for obtainment of chemicals, biofuels, materials and energy has become each time larger due to environmental, political and economical problems of non-renewable energies utilization. Among several products that can be obtained from lignocellulosic biomass, which is a renewable source, there is furfural, a chemical from which many other value added chemical products can be obtained. The main route for furfural production consists of an acid hydrolysis of hemicelluloses present in lignocellulosic biomass to obtain xylose, which goes through a dehydration reaction to produce furfural. Due to the presence of an aldehyde group and a conjugated system of double bounds, furfural can go through several reactions, allowing the production of a range of value added products. In this sense, this article performs a review about mechanisms of furfural production from lignocellulosic biomass, highlighting its chemical properties which enable its utilization in different industrial applications of economic interest.

“…10,11 In recent years, furfural has gained great attention from researchers and bio-industries owing to its expected increasing demand due to the broad usage of this versatile chemical in many industries. [12][13][14][15] Furfural can be used as a feedstock for 2-methylfuran, 16 2-methylhydrofuran, 17 -valerolactone, 18,19 furfuryl alcohol, 20 carboxylic acid, 21 tetrahydrofurfuryl alcohol 22 and long-chain hydrocarbons 23,24 during the production of potential biofuels and fuel additives.…”

BACKGROUND Furfural is an interesting compound that can be produced from renewable and sustainable resources and is used in platform chemicals for the synthesis of biofuels and other chemicals. However, a recovery step is required to separate furfural from lignocellulosic hydrolysates when cellulose‐based raw materials are used. In this work, nanofiltration (NF) and reverse osmosis (RO) processes have been evaluated to purify or concentrate synthetic furfural solutions. RESULTS Two NF membranes (NF90 and NF270) and three RO membranes (XLE, BW30 and SW30) were evaluated to recover furfural from high‐concentrated solutions containing 9 g furfural L−1. Rejection percentages and permeate flux performances were determined and membranes were characterized by X‐ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM). Results indicated that higher trans‐membrane flux could be obtained by NF membranes, being the highest when using NF membranes (260 ± 14 L m−2 h−1) and the lowest with the BW30 membrane (3.3 ± 0.7 L m−2 h−1) working at 20 bar. On the other hand, NF270 allowed the passage of furfural (around 84 ± 3%), while the other tested membranes (NF90, XLE, SW30 and BW30) rejected it (between 67 ± 2 and 90 ± 3%). CONCLUSION For this reason, it can be concluded that NF270 will be an option for furfural purification, while NF90 and RO membranes could be used for concentration purposes. © 2019 Society of Chemical Industry
