The increasing scarcity of fossil raw materials, together with the need to develop new processes and technology based on renewable sources, and the need to dispose of an increasing amount of biomass-derived waste, have boosted the concept of biorefineries. Both 1G and 2G biorefineries are focused on the obtention of biofuels, chemicals, materials, food and feed from biomass, a renewable resource. Fumaric acid, and most compounds involved in the Kreb cycle, are considered key platform chemicals, not only for being acidulants and additives in the food industry, but also for their prospective use as monomers. This review is focused on the biotechnological processes based on fungi, mainly of the Rhizopus genus, whose main product is fumaric acid, on the process conditions, the bioreactors and modes of operation and on the purification of the acid once it is produced.

“…Besides, the reason why VPP needs lower concentrations of glycerol to obtain good selectivity to AA (see catalytic tests) can also be attributed to the relativelyl imited availability of the redox active sites on the surface, ap eculiar feature of this catalyst also reported for other reactions. [56] To have ag ood fraction of V 5 + sites availablef or oxidation (see XPS results, Ta ble 1), it is necessary to keep the partial pressure of the reactants low and the partial pressure of O 2 (relatively) high.…”

The design of suitable catalysts for the one-pot conversion of glycerol into acrylic acid (AA) is a complex matter, as only fine-tuning of the redox and acid properties makes it possible to obtain significant yields of AA. However, fundamental understanding behind the catalytic phenomenon is still unclear. Structure-reactivity correlations are clearly behind these results, and acid sites are involved in the dehydration of glycerol into acrolein with vanadium as the main (or only) redox element. For the first time, we propose an in-depth study to shed light on the molecular-level relations behind the overall catalytic results shown by several types of V-containing catalysts. Different multifunctional catalysts were synthesized, characterized (>X-ray diffraction, X-ray photoelectron spectroscopy, Raman spectroscopy, temperature-programmed reduction, and temperature-programmed desorption of ammonia), and tested in a flow reactor. Combining the obtained results with those acquired from an in situ FTIR spectroscopy study with acrolein (a reaction intermediate), it was possible to draw conclusions on the role played by the various physicochemical features of the different oxides in terms of the adsorption, surface reactions, and desorption of the reagents and reaction products.

“…Recently, other renewable chemical platforms have also been reported to yield MA via oxidation, e.g., gas phase oxidation of bio-butanol, 5-hydromethylfurfural (HMF) and levulinic acid. Thus far, the yield of MA from biobutanol is lower than that obtained from furfural [10].…”

An alumina-supported vanadium oxide catalyst (13.9 wt. % of vanadium oxide) has been tested on the gas phase oxidation of furfural and characterised by different techniques. These studies have showed that catalyst unavoidably deactivates by deposition of maleates and resins over the surface. Full regeneration is accomplished by burning off these deposits at 773 K. The studies have also demonstrated that if the primary contact occurs at temperatures at which furfural conversion is low and then the temperature is increased in a low to high temperature mode, an intense deposition of maleates and resins takes place and the catalyst is rapidly deactivated. The increasing of the temperatures does not result in removal of deposits but accelerates the deposition. Under this protocol the yield of maleic anhydride never exceeded 30 %, irrespective of the reaction conditions (temperature and O 2 /furfural mol ratio). On the contrary if the catalyst first contacts the reaction mixture at high oxidising potential, then the rate of maleate and resins deposition is much slower and so is the deactivation rate and the catalyst can display a higher yield of MA for longer period of time. A high oxidizing potential can be accomplished at high reaction temperature (close to full conversion). Higher oxidising potential 2 at a given high temperature can be accomplished by increasing the O 2 /furfural mol ratio. Thus, for example, first contacting the catalyst at 593 K (full conversion), 1 vol. % of furfural and an O 2 /furfural mol ratio = 10, maleic anhydride yield of 68 % was initially obtained and was still greater than 50 % after 15 h on stream. When contacting at 573 with 1 vol. % furfural and 29 vol. % of O 2 , the maleic anhydride yield was initially close to 75 % and above 60 after 15 h.
