“…In addition, the presence of lignin may have affected furfural production. Lamminpaa et al [37] showed that lignin can increase the pH of a reactant solution, leading to low conversion of xylose into furfural.…”

Palm oil empty fruit bunches (POEFBs) can be converted into levulinic acid (LA) and furfural, which are among the top building-block chemicals. The purpose of this study was to investigate separate and simultaneous kinetic model parameters for LA and furfural production from POEFBs, which were pretreated by soaking in aqueous ammonia (SAA). The highest LA yield, which was obtained at a reaction temperature of 170°C after 90 min in an acidic solution with a concentration of 1 M, was 52.1 mol%. The highest furfural yield was 27.94 mol%, which was obtained at a reaction temperature of 170°C after 20 min in an acidic solution with a concentration of 0.5 M. SAA pretreatment affected activation energy in glucose degradation reactions and favoured direct conversion of hemicellulose to furfural. The activation energy of LA production (EakHMF) increases with higher acid catalyst concentration, and the activation energy of furfural production (EakXYN) decreases with higher acid concentration. These trends in the activation energy occurred in both separate and simultaneous kinetic models. Simultaneous kinetic model is better to calculate kinetic parameters of LA and furfural production than separate kinetic models because the simultaneous kinetic model had a lower sum of square error (SSE) when estimating kinetic parameters.

“…The HPLC analysis did not identify any significant amount from products originating from side reactions between xylose and FUR, as well as the isomerization of the intermediate back to xylose. Previous kinetic studies have used either scheme 1 [40] or 2 [39,41,42] using homogeneous catalysts. Different formation pathways include isomerization of xylose to other pentoses such as lyxose and xylulose.…”

The production of furfural (FUR) from xylose was carried out using sulfated zirconia (SZ) on cordierite, alumina on cordierite and commercially-available polymeric solid catalysts (Amberlyst DT and Nafion NR40) to provide insights into the reaction pathways and kinetics for the dehydration of xylose in aqueous phase.Experiments conducted at three temperatures were investigated (170, 190 and 210 °C) in a stirred microwaveassisted batch reactor, which established the optimal conditions to obtain the highest FUR yield as well as extensive and fast xylose conversion. The maximum FUR yields obtained from xylose were 41 mol% when using SZ on cordierite in 2 min (at 210 °C), 43 mol% when using alumina on cordierite in 30 min (at 210 °C) and 48 mol% for an auto-catalyzed system in 60 min (at 210 °C). Based on the experimental results, a reaction mechanism was proposed considering the formation of an intermediate from xylose when solid acid catalysts were added. After five reusability cycles using SZ, this catalyst can be regenerated with a similar performance and similar FUR yield on the 6 th cycle.

“…This range cannot be obtained by the self-condensation of small molecules, but biomass can be transformed into the needed intermediates: the aldehydes. Dehydration of sugar carbohydrates leads to the formation of aldehydes such as furfural and hydroxymethylfurfural (HMF) [104]. These compounds are essential intermediates in biorefineries for production of liquid alkanes with fuel properties, and the study of their upgrading is a key of interest in the last years [45,105].…”

“…Other researches considered reactions in biphasic configurations, using organic solvents such as methanol [119] or hexane [104] to combine the reaction with an extraction that prevents the oligomerizations. With the same aim, bifunctional catalysts can play an important role: if the reaction is carried out under H 2 atmosphere and the catalyst combines the basic sites with a noble metal (generally Pd), condensed adducts can be partially hydrogenated, increasing their solubility in the aqueous phase and preventing their strong adsorption on basic sites that promote the oligomerization [113,133].…”

Although less studied than acid-catalyzed reactions, mainly because of their marginal interest in petrochemical processes, base-catalyzed reactions (either homogeneous or heterogeneous) play a key role in the upgrading of biomass-derived platform molecules. As in most of the chemical processes, the replacement of homogeneous catalysts by heterogeneous catalysts is of key interest. This article reviews the state of the art in the most important base-catalyzed reactions in the biofuel manufacture (biodiesel from triglycerides) and the upgrading of biomass-derived platform molecules (such as acetone, ethanol, furfural, 5-hydroxymethylfurfural, or acetic acid). Transesterification reactions, aldol condensation (alone or in combination with other reactions), and ketonization are the main reactions involved in these biorefinery processes. Reviewed are the most common catalysts proposed for these reactions (mainly heterogeneous), as well as the proposed mechanisms for these reactions, and the main factors governing catalyst deactivation when used in each of these reactions.
