“…below 100 ºC) is not able to break the cross-links between the WUAXs and the wall matrix (Izydorczyk & Biliaderis, 2007). In order to improve the AXs extraction yield from different biomass, several techniques, such as hydrothermal treatments (Bobleter, 1994;Buranov & Mazza, 2010;Carvalheiro, Garrote, Parajó, Pereira, & Gírio, 2005;Dien et al, 2006;Garrote, Domínguez, & Parajó, 1999;Garrote, Domínguez, & Parajó, 2001;Garrote, Domínguez, & Parajó, 2002;Kim, Hendrickson, Mosier, & Ladisch, 2009;Lavarack, Griffin, & Rodman, 2000;Li, Converse, & Wyman, 2003;Maes & Delcour, 2002;Mok & Antal, 1992;Nabarlatz, Farriol, & Montané, 2004;Negahdar, Delidovich, & Palkovits, 2016;Reisinger et al, 2013;Shen & Wyman, 2011;Tekin et al, 2014), chemical-solvent extractions (Adams et al, 1955;Aguedo, Fougnies, Dermience, & Richel, 2014;Bataillon, Mathaly, Nunes Cardinali, & Duchiron, 1998;Buranov & Mazza, 2010;Choteborská et al, 2004;Doner, Chau, Fishman, & Hicks, 1998;Höije, Gröndahl, TØmmeraas, & Gatenholm, 2005;Hollmann & Lindhauer, 2005;Kim, Kreke, & Ladisch, 2013;Kusema et al, 2011;Lavarack, Griffin, & Rodman, 2002;Maes & Delcour, 2002;Shen & Wyman, 2011;Swennen, Courtin, Lindemans, & Delcour, 2006;Xu et al, 2006;Yao, Nie, Yuan, Wang, & Qin, 2015;…”

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.

“…This treatment could also open up the cellulose fibers for further reactions and increase the extractability of lignin during the subsequent pulping process (Lavarack et al 2000;Garrote et al 2003). Procedures currently used in pretreatment include hot-water prehydrolysis, wet oxidation (Arvaniti et al 2012), steam pretreatment (Brownell and Saddler 1987), and ammonia fiber explosion (Lee et al 2010).…”

Despite increasing demand for dissolving pulps from raw material, production costs remain quite high compared to regular paper pulp. Research literature to date has focused on improving performance and quality but has not simultaneously explored how to improve yield, which typically falls below 35%. Dissolving pulp from bamboo, as a widely available, high-quality raw material, was investigated with dilute acetic acid pre-hydrolysis before cooking and cold caustic extraction prior to bleaching. It was found that dilute acetic acid in the pre-hydrolysis stage could speed up the degradation of hemicellulose in bamboo and improve the diffusion of the cooking liquor in bamboo fiber compared with hot-water treatment. The dissolving pulp from bamboo was produced with 93% α-cellulose, 90% ISO brightness, 959 mL/g viscosity, 5.23% xylans, and 0.17% ash. The overall yield on the basis of raw material was 37%, which was higher than other documented processes using other agents in prehydrolysis.

“…Compared with the kinetic results in the traditional model, the modified model exhibited a decrease in the activation energy (48.1 kJ/mol) and frequency factor (4330 min À1 ) after using h d . However, these constants, which were determined in the modified model, were of the same order as those in most literature on pentosan hydrolysis of non-woody feedstock (Arslan and Saraçoglu-Eken, 2012;Lavarack et al, 2000;Romero et al, 2010).…”
