“…94 35 Xu et al used synchrotron WAXS and SAXS to measure structural changes of sorghum after biomass pretreatment. 69,147 The 2D SAXS pattern of untreated sample appeared as diamond-shaped streak elongated on the equator (Figure 21). The equatorial streak was attributed to the presence of microvoids 40 orientated along the fibre axis.…”

“…The meridional scattering was assigned to scattering from the periodic interval along the microfibril. 69,147 After the alkali pretreatment, the diamondshaped pattern transformed into an isotropic scattering pattern, indicating a decrease in orientation and length of microvoids 45 ( Figure 21). 147 In related work, Xu et al analyzed the size of the microvoids and found that total volume increased after dilute acid pretreatment.…”

“…For example, alkali pretreatment is more effective with low lignin-content biomass [11]. Biomass composition also changes significantly during biomass processing [12], so a fast and accurate determination of biomass composition is critical for accelerating biomass utilization.…”

“…Maximising the xylan recovery by diluted nitric acid pretreatment was therefore assessed by simultaneously minimising lignin to ensure pretreatment effectiveness without considering the content of glucan. Glucan is supposed to be retained in this study as the mild condition used may protect the cellulose structure and thus prevent its hydrolysis (Xu et al, 2013). Table 3 shows the components (glucan, xylan and lignin contents) obtained via 2 5−1 fractional factorial design.…”

Pretreatment enhances bioconversion of lignocellulosic biomass by disrupting and changing the properties of its material. This work is intended to examine the influence of several variables involved in the recovery of xylan from oil palm frond bagasse (OPFB) in the pretreatment of diluted nitric acid. Through a fractional factorial design of 2 5−1 the temperature variables ranged from 37°C-90°C, time of reaction varied from 6-24 hr, solid loading ranged from 5%-20%, concentration of acid changed from 0.01%-1.0%, and agitation between yes or no were evaluated. As much as 27.63% of xylan successfully recovered at mild condition and it was completely hydrolysed as the pretreatment condition increased. This study found solid loading of 5% and acid concentration of 0.01% at 37°C for 24 hr pretreatment without agitation were best to maximise xylan recovery and minimise lignin content simultaneously. Temperature was the most important factor studied for the recovery of xylan with a contribution of 29.34%. The findings suggest that studying the condition influencing acid pretreatment is crucial towards improving pretreatment process.
