“…However, there are still some drawbacks concerning the rapid degradation of 5-HMF to levulinic acid (in the presence of water) and the use of organic solvents (purification and separation issues). Recently, we have developed catalysts for the selective oxidation of 5-HMF to 2,5-diformylfuran (DFF) 154), 155) and some groups were focusing on FDCA synthesis (2,5-furandicarboxylic acid), a green alternative to terephthalic acid 156) . Most of the catalytic systems are based on noble metals, with FDCA yields over 95 % and on vanadium phosphate oxides with DFF yield of 83 %.…”

Biomass valorization is a booming field. Especially, the valorization of platform molecules by catalytic processes has driven a large interest in the recent years, and many groups are actively working on the transformation of biosourced substrates to a variety of upgraded chemicals. In this context, in the present paper we put in perspectives the scientific works of our research team. We first classified catalytic transformations of industrial interest according to the number of carbons of the starting material, from C1 to C6. They involve, among others, acid catalysts (e.g., for glycerol dehydration), redox catalysts (e.g., for 5-HMF conversion to diformylfuran), acid and redox catalysts (e.g., for direct acetalization of alcohols), or complex multifunctional catalysts, especially for the Guerbet reaction. Further, we also developed what we called 'toolboxes,' which are general concepts or technologies with a broader field of applications. For example, we adapted the two zones fluidized bed reactor (TZFBR) concept to the single reactor continuous regeneration of coking catalysts. Further, we designed a completely new high throughput platform enabling synthetizing, characterizing and testing the performances of many catalysts for considerably accelerating the catalysts discovery/optimization loop.

“…Glucose, which is the most abundant and the cheapest monosaccharide, has been considered as the preferred feedstock for the production of HMF. However, HMF is typically produced from glucose with low yields, which is attributed to the stable pyranoside ring structure of glucose (Hu et al, 2012). Thus, current technologies in general include an additional isomerization step of glucose to fructose, since dehydration of fructose to HMF takes place with better selectivity and higher rates (Chheda et al, 2007;Grande et al, 2012).…”

-5-Hydroxymethylfurfural (HMF) is a key renewable platform compound for production of fuels and chemical intermediates. The production of 5-hydroxymethylfurfural (HMF) from fructose dehydration was studied using H 3 PO 4 as catalyst, in organic/water system with different solvents (acetone, 2-butanol and ethyl ether). The effect of fructose concentration, temperature and acid concentration was investigated in acetone/water medium. The increase in fructose concentration favors the formation of condensation products and rehydration products are favored at high acid concentration. The solvents exhibited similar performance when the volume ratio of organic to aqueous phase was 1:1, but when this ratio increases to 2:1, the HMF yield obtained with ether was much lower. NaCl addition to the aqueous phase promoted the extraction of HMF to the organic phase, with an HMF yield of 80% in the case of 2:1 acetone/water medium.

“…In turn, LA can be dehydrated and hydrogenated to ϒ-valerolactone (GVL) which can be upgraded to liquid alkenes [27]. However, in spite of the great number of papers reported, the overall production of bio-fuels and bulk-chemicals from biomass hydrolysis is currently generally indicated as leading to low yields and high production costs [25,26].…”
