ABSTRACT Recent approaches to furfural synthesis from hemicellulosic biomass and pentose sugars with both homogeneous and solid acidic catalysts have been summarized by addressing the associated sustainability issues. The features of deconstruction of hemicellulosic biomass by acid hydrolysis to produce pentose sugar feedstock for furfural have been discussed in brief. Several strategies including solvent extraction in a biphasic process, application of surface functionalized materials such as acidic resins, mesoporous solids and mechanistic insight in limited cases are discussed. The present status of the promising furfural platform in producing second generation biofuels (furanics and hydrocarbon) is reviewed. The performances of each catalytic system are assessed in terms of intrinsic reactivity and selectivity toward furfural production. Overall, this minireview attempts to highlight the scope of further developments for a sustainable furfural process and upgrading to fuels.

    ABSTRACT: Recently, furfural, “the sleeping beauty bio-renewable chemical” has gained a renewed attention as a potential chemical for the production of biofuels and biochemicals. Furfural is the most commonly produced industrial chemical because its production is very flexible. It is one of the top value-added chemicals that can be produced from biomass. Furfural and its derivatives have been extensively used in plastics, pharmaceutical and agrochemical industries. Furfural is a natural precursor to a range of furan-based chemicals and solvents such as dihydropyran, methyltetrahydrofuran, tetrahydrofuran, methylfuranfurfuryl alcohol, tetrahydrofurfuryl alcohol and furoic acid. Furfural and its derivatives have been widely applied as fungicides and nematicides, transportation fuels, gasoline additives, lubricants, resins, decolorizing agents, jet fuel blend stocks, drugs, insecticides, bio-plastics, flavor enhancers for food and drinks, rapid all-weather repair system for bomb-damaged runways and pot holes and also for wood modification and book preservation.

    • "An experimental design of factorial 2 4À1 was carried out to optimize hydrolysis conditions (Table S2). The limits for hydrolysis conditions, especially the temperature below 100 °C, were chosen to restrict the xylose dehydration into furfural as described in recent reviews [25] [30] [32] [41] [42]. "

    ABSTRACT: The purpose of this study is to target well-defined xylooligosaccharides by controlled sulfuric acidic hydrolysis of beechwood xylans. Parameters such as sulfuric acid and xylan concentrations, hydrolysis duration and temperature have been investigated, allowing optimum conditions to be determined (0.7 M H2SO4, 90 °C, 45 min). The obtained xylooligosaccharides show a well-defined structure and have been characterized using several techniques such as 1D and 2D nuclear magnetic resonance spectrometry and matrix-assisted laser desorption/ionization-time of flight mass spectrometry. This work demonstrated that mild acidic hydrolysis conditions enable the reproducible production of xylooligosaccharides containing, on average, six xylose units and only one 4-O-methyl-D-glucuronic acid unit likely positioned at the non-reductive chain-end.

    • "Furfural, a potential platform for biofuels, is one of the most common industrial chemicals derived from lignocellulosic biomass [12]. Not only furfural itself is an important chemical solvent, various furfural derivatives also have a large demand in the plastic, food, pharmaceutical, and agricultural industries [1] [13]. "

    ABSTRACT: This study presented a new approach to produce furfural from steam explosion liquor of rice straw (SELRS) by solid acid catalysts (HZSM-5). The maximum furfural yield was 310 g kg−1 under the optimum conditions: HZSM-5 addition 60 g kg−1 sugar, reaction temperature 160 °C, extraction steam flow rate 2.5 cm3 min−1 and total sugar concentration 61.4 kg m−3. HZSM-5 catalysts were reused for 3 runs and the catalytic activity recovered 88% after regeneration through calcination. To improve furfural production efficiency, polymerization inhibitor was added to the reaction system under the optimum conditions. As a result, furfural yield (375 g kg−1) was increased by 21% with the addition of 15 g kg−1 of 4-Methoxyphenol, which showed a superior effect than that of p-tert-Butylcatechol (352 g kg−1 of furfural yield) with the same additive amount. Therefore, HZSM-5 combined with 4-Methoxyphenol obviously improved the furfural conversion performance from SELRS.
