The extraction/hydrolysis process of arabinoxylans from destarched wheat bran was studied in this work using different mesoporous silica supports and the corresponding RuCl3-based catalysts. The effects of temperature, time, catalyst supports and ruthenium catalysts were investigated and discussed in terms of the arabinoxylans extraction yield and their polymerization degree. Relatively high temperatures (180 ºC), short extraction times (10 minutes) and RuCl3 supported on Al-MCM-48 led to a high amount of arabinoxylans extracted (78%) with a low molecular weight (9 KDa). Finally, a relation between the operating conditions, the arabinoxylans extraction yield and the molecular weight was stablished based on the obtained results.

“…One is that there may exist an abundancy of partially dehydrated intermediates generated in the process of fructose dehydration to HMF at low reaction temperatures (<130°C), and the other is that side reactions such as the polymerization of these intermediates and alcoholysis of HMF have occurred in ethanol. 27 In our previous studies, 16 it was found that adding a certain volume of DMSO (dimethylsulfoxide) into ethanol could efficiently improve the yields of the furan products without causing much trouble in the product separation. Thus, 0.3 mL DMSO mixed with 0.7 mL ethanol was used as the reaction solution.…”

“…Moreover, 0.250 g of catalyst was added to 30 mL of NaCl solution (0.05 mol/L), and the mixture was subjected to ultrasonic vibration for 60 min at room temperature, causing the full H + and Na + response on the catalyst surface. After centrifuging the mixture, 10 mL of solution were titrated with NaOH (0.05 mol/L), and the magnetic solid acid and sulfonic acid values were calculated (Wang et al 2011).…”

Solid acid catalysts show good catalytic depolymerization behavior for lignocellulose. A stable core-shell structured magnetic solid acid catalyst (MSAC), Fe3O4/C-SO3H, was prepared from glucose, concentrated sulfuric acid, and modified magnetic particles of Fe3O4, which was used as the core. The effects of the carbonization and sulfonation processes on the activity of the catalyst were investigated. The results showed that preparation conditions had great influence on the quantity of the acidic groups (sulfonic, carboxyl, and hydroxyl groups) and the stability of magnetic catalysts. The best preparation conditions for MSAC were 3 h of carbonization time, 450 °C as the carbonization temperature, 9 h of sulfonation time, and 90 °C as the sulfonation temperature. Its surface topography, functional group, chemical composition, and magnetic properties were characterized by analysis instrument. Furthermore, the catalyst was stably dispersed in the reaction system, quickly separated from the reaction system using an external field, and reused many times; 44.3% of xylose yield was obtained at 160 °C for 16 h. The catalyst was used repeatedly more than 3 times, and the recovery over 89%. The depolymerization of corncobs was achieved by magnetic catalyst, representing the depolymerization characteristics of real lignocellulose. This data can be used as a reference for the subsequent use of biomass resource.
