“…resource availability and diminution, pollution and global warming has sparked significant interest into utilization of biomass as a future renewable carbon source for fuels and valueadded chemicals. In terrestrial biomass, carbohydrates account for up to 75% of the renewable carbon, 1 and several catalytic routes have been developed for transformation of carbohydrates to useful products via heterogeneous, homogeneous and enzymatic processes. 2 This includes in particular compounds like 5-hydroxymethylfurfural (HMF) which has been demonstrated to serve as a platform molecule for the production of various biofuels 3 and chemicals such as, e.g.…”

“…Furfural is the key derivative of xylose with a broad spectrum of industrial applications, such as the production of plastic, pharmaceuticals, and agrochemical products and numerous non-petroleum-derived chemicals from saccharides. About 250,000 tons of furfural, probably the only unsaturated, large volume, organic chemical, are prepared from carbohydrate sources 12,13 annually.…”

Hemicellulose, the second, most common polysaccharide in nature constitutes approximately 20-35% of lignocellulosic biomass. Effective utilization of biomass, hitherto underutilized, is gaining tremendous importance for the production of energy, fuels, and chemicals. Amongst the vast array of chemicals derived from lignocellulosics, furfural is the key chemical that fi nds wide applications in oil refi ning, plastics, pharmaceutical and agrochemical industries. There is no synthetic route for the production of furfural. A few conventional technologies currently in practice for its separation and subsequent isolation are appropriately reviewed. Major disadvantages associated with processes currently used for the production of furfural based on acid-catalyzed hydrolysis have been discussed. A need to develop a process which is devoid of all the shortcomings associated with conventional process is emphasized. Several important aspects of chemistry underlying the acid hydrolysis of xylose are discussed. The importance of myriad pre-treatment steps involved to surmount the physical and chemical barriers and to liberate xylose from the confi nes of acid-resistant layer of lignin has been emphasized. New developments in the production of furfural from cyclodehydration of xylose using solid acid catalysts in the recent past have been reviewed appropriately in present communication. Finally, the production of furfural and furfuryl alcohol, their domestic market and export in China deserve some coverage and therefore have appropriately been discussed as well.

“…As a single class of natural products carbohydrates are the major biofeedstocks from which to develop industrially and commercially viable organic chemicals and materials as a replacement of petrochemically derived products in a future carbohydrate economy [358]. Cellulosic material can potentially meet our fuel and chemical feedstock needs if it can be effi ciently converted into sugar molecules such as glucose with higher energy densities than the parent biomass [359].…”
