Abstract: Crystallinity is an important property of lignocellulosic biomass due to its significant effect on acid/enzymatic hydrolysis. Normally, physicochemical analysis, such as powder X-ray diffraction and nuclear magnetic resonance, is used to reveal the crystallinity content. However, these analytical methods are expensive and laborious. In this context, methods that rapidly predict the crystallinity are important, even if used only for screening calibration. Thus, we intend to show the potential of near-infrared s… Show more

“…The olive mill residue showed the highest CrI (55.8%), while in citrus waste biomass it was less than 20% (Figure 2). These values are consistent with those previously reported for agrifood residue [13,45,46].…”

“…The crystalline index revealed a 64% of crystallinity for holocellulose, which is similar to those found for hollocellulose extracted from flax stem, rose stems and banana peels [42,47,48]. However, crystalline index of cellulose II was 83%, which was better than that obtaneid for cellulose II extracted from sago seed shells, sugarcabe bagasse, alfa fibers and red algae waste [44,49].…”

“…XRD analysis on WCCB, extracted wax, and char were performed on a Siemens D5000 diffractometer using Cu‐Ka radiation (0.1542 nm) from 2 θ = 2 to 80° at 0.01° steps. The crystallinity index (CI) for cellulose (CI c ) and wax (CI w ) were determined using the adjusted deconvolution method 26,27 CI=()AitaliccryAcry+Aitalicam×100 where A cry is the adjusted crystalline peak area, and A am is the adjusted broad peak area of the amorphous component.…”
