“…The results (Table 1) showed that only the time and temperature variables (X1 and X2) had a significant effect on the conversion % (p < 0.05), whereas the O 2 pressure and the catalyst load did not affect the conversion. These results agree with those obtained in similar studies that used polyoxometalates in the catalytic valorization of biomass, in which time and temperature were the main factors in the process [25,26]. The slightly negative coefficients of the model are possibly due to the proximity to the zero point of the design to a maximum of the model, such that when it was increased in absolute value, the effect of the variable decreases.…”

The catalytic oxidation of phenethoxybenzene as a lignin model compound with a β-O-4 bond was conducted using the Keggin-type polyoxometalate nanocatalyst (TBA)5[PMo10V2O40]. The optimization of the process’s operational conditions was carried out using response surface methodology. The statistically significant variables in the process were determined using a fractional factorial design. Based on this selection, a central circumscribed composite experimental design was used to maximize the phenethoxybenzene conversion, varying temperature, reaction time, and catalyst load. The optimal conditions that maximized the phenethoxybenzene conversion were 137 °C, 3.5 h, and 200 mg of catalyst. In addition, under the optimized conditions, the Kraft lignin catalytic depolymerization was carried out to validate the effectiveness of the process. The depolymerization degree was assessed by gel permeation chromatography from which a significant decrease in the molar mass distribution Mw from 7.34 kDa to 1.97 kDa and a reduction in the polydispersity index PDI from 6 to 3 were observed. Furthermore, the successful cleavage of the β-O-4 bond in the Kraft lignin was verified by gas chromatography–mass spectrometry analysis of the reaction products. These results offer a sustainable alternative to efficiently converting lignin into valuable products.

“…10 Sherbi et al 11 have investigated the selective production of ring-opening products, particularly secondary alcohols, from furans and hydrogen under mild reaction conditions, thereby demonstrating a route to produce alcohols from lignocellulosic biomass using a bifunctional catalyst system consisting of platinum on a Keggin-type polyoxometalate. 12 The use of alcohols as e-fuels can also have a positive effect on the combustion behaviour. Jakob 13 investigated various fuels at an optically accessible single-cylinder diesel engine at a dened part-load operation point with fuel individual EGR rates for 100 ppm NO x raw emissions and fuel individual starts of the single main injection for xed center of combustion.…”

“…This can be investigated effectively by using statistical and modeling tools like design of experiments (DoE). 21 In this study, a sensitivity analysis for different parameters of the ionosolv fractionation was performed for beech wood as an industrially relevant substrate. A Box−Behnken DoE was used to reveal the relative importance of several reaction parameters on the selective dissolution of the hemicellulose.…”

The recently developed polyoxometalate (POM)− ionosolv concept offers an interesting strategy to generate two valuable product streams from lignocellulosic biomass, a solid cellulose-rich pulp and short-chain carboxylic acids like formic acid and acetic acid in a simple and cost-efficient manner. This study aimed to find optimum parameters for the two steps of the transformation by performing a sensitivity analysis on the initial ionosolv fractionation step as well as kinetic investigations of the following POM-catalyzed oxidation step. The results were transferred to the POM−ionosolv concept to find the overall process optimum. Beech wood was used as an industrially relevant substrate for ionosolv fractionation with the low-cost ionic liquid triethylammonium sulfate, [TEA][HSO 4 ], and the HPA-5 [H 8 PV 5 Mo 7 O 40 ] POM catalyst for the oxidation of the dissolved components in an oxygen atmosphere. As the most seminal finding, we defined optimum conditions of 125 °C, 1200 rpm, 30 bar oxygen, and 24 h reaction time in ionic liquid containing 70% water, achieving 72% xylose extraction from beech wood, which resulted in a 39% formic acid yield. We suggest that the fractionation and catalytic conversion are carried out at different water contents for maximum conversion efficiency for each step.
