“…Current uses are mainly for the production of furfurylalcohol (resin production), linking foundry sand, lubrication oil extraction, and a novel application is as a nematicide. For the future a role is foreseen in green fuel production, like the furfural derived compound MTHF (methyltetrahydrofuran) in the so-called Pseries, developed in the USA (Kar and Deveci 2006). However, it is also considered as a platform chemical for the (near) future: a compound which is pinpointed as important chemical intermediate from biomass, not produced in major quantities in petroleum refineries.…”

At Delft University of Technology theoretical and experimental research is carried out towards selective production of furfural from renewable biomass. Furfural is an interesting molecule that has been identified as a platform chemical for a multitude of chemical products and fuel (additives).Acidic biomass hydrolysis and subsequent dehydration of the obtained C 5 sugar xylose leads to furfural. The reaction selectivity is a point of concern for reactor design, as furfural can further react to loss products. The residue of this process mainly consists of the remaining main biomass constituents, cellulose and lignin. Mineral matter is to a large extent extracted to the acid in the primary hydrolysis. This implies that the residue has the potential to be a better feedstock for thermo-chemical conversion, as e.g. alkali and chlorine species-now extracted-potentially cause different types of problems (slagging, fouling, agglomeration etc.).An interesting option for example might be to convert this improved feedstock into synthesis gas via a gasification process, which then needs to be conditioned and upgraded for the production of green transportation fuels. In this line, a new biorefinery generation is created, which selectively uses the hemi-cellulose part of biomass.

“…In this context, the possibility of upgrading these already valuable chemical intermediates into other classes of more added-value compounds, such as 2-methyltetrahydrofuran (2-MeTHF) and 2-butanol (2-BuOH), represents a smart challenging possibility. Regarding the first one, it is a versatile aprotic and hydrophobic organic solvent, which is non-toxic and non-ozone depleting in nature [27] and a promising biofuel [28], being identified as a key component for P-series fuels [29]. On the other hand, 2-BuOH is mainly used for the synthesis of methylethylketone, but very recently it has found other applications both as solvent and fuel additive, thanks to its high octane number [30].…”

Cascade Strategy for the Tunable Catalytic Valorization of Levulinic Acid and γ-Valerolactone to 2-Methyltetrahydrofuran and Alcohols

A cascade strategy for the catalytic valorization of aqueous solutions of levulinic acid as well as of γ-valerolactone to 2-methyltetrahydrofuran or to monoalcohols, 2-butanol and 2-pentanol, has been studied and optimized. Only commercial catalytic systems have been employed, adopting sustainable reaction conditions. For the first time, the combined use of ruthenium and rhenium catalysts supported on carbon, with niobium phosphate as acid co-catalyst, has been claimed for the hydrogenation of γ-valerolactone and levulinic acid, addressing the selectivity to 2-methyltetrahydrofuran. On the other hand, the use of zeolite HY with commercial Ru/C catalyst favors the selective production of 2-butanol, starting again from γ-valerolactone and levulinic acid, with selectivities up to 80 and 70 mol %, respectively. Both levulinic acid and γ-valerolactone hydrogenation reactions have been optimized, investigating the effect of the main reaction parameters, to properly tune the catalytic performances towards the desired products. The proper choice of both the catalytic system and the reaction conditions can smartly switch the process towards the selective production of 2-methyltetrahydrofuran or monoalcohols. The catalytic system [Ru/C + zeolite HY] at 200 • C and 3 MPa H 2 is able to completely convert both γ-valerolactone and levulinic acid, with overall yields to monoalcohols of 100 mol % and 88.8 mol %, respectively.

“…In a bio-based economy, furfural can also replace or substitute some oil derivatives as platform chemical and be a starting material for liquid fuels production. In fact, furanic biofuels have lately been referred as representing a very interesting option to current biofuels, showing advantageous qualities, Mascal and Nikitin [2008], Kar and Deveci [2006]. This is especially relevant when also considering the increasing concern on the competition of first generation biofuels for feed and food crops.…”

The interest for furfural has increased in the last years due to its potential for competing with oil derivatives as platform chemical. In addition, furfural, derived from C 5 sugars, can play a key role in the valorization of the hemicellulose contained in biomass when considering the development of a modern biorefinery concept. The development of such new and competitive biorefinery processes must be based on accurate kinetic data for the reactions involving furfural in the conditions used for its production.This work addresses the determination of furfural destruction kinetics in aqueous acidic environment, using sulphuric acid as catalyst, in the temperature range 150 -200• C, acid concentration range 36.4 -145.5 mM and furfural initial concentration between 60.4 and 72.5 mM. These studies were carried out using a recently built lab-scale titanium reactor that enables liquid phase reactions in a relatively broad range of conditions.The obtained results show that destruction of furfural follows first-order reaction kinetics within the range of temperature and acid concentration evaluated. Moreover, the proposed kinetic model takes into account the effects of temperature and acid dilution on the ions activity, and thus H 3 O + , by using the electrolyte Non-Random Two-Liquid (eNRTL) model. By using this approach, the rate constant dependence on temperature could be described by the Arrhenius law and thus the activation energy could be estimated as being 125. Contrarily to what is reported in previous works, formic acid formation from furfural under the tested conditions can be regarded as playing a far less pronounced role than suggested before.
