“…However, dilute acid is normally preferred as concentrated acid, which is toxic and corrosive, and results in the production of high levels of inhibitors including furfural derivatives, acetic acid, phenolics, and other aromatic compounds [31]. Pretreatment with acid may be conducted at high temperature for a short time or low temperature for a longer period [32].…”

Lignocellulosic biomass from weedy plants represents a potential alternative feedstock for economic production of bioethanol. Large numbers of weedy plant species are growing all over the world. Characteristics such as high dry matter yield, low water and nutrient requirements for growth, and cellulose contents make weedy plants very attractive as feedstock for bioethanol production. However, like other lignocellulosic feedstock, the complex structure presents resistance and recalcitrance to processes of conversion to bioethanol. Several weedy plants have been studied to determine their physical characteristics and suitability for bioethanol production. Different conversion techniques have been employed to increase monomer sugars and hence bioethanol yield. This chapter discusses processes and current research activities in bioconversion of weed biomass to bioethanol.

“…Subsequently, the powdered form of SB was soaked in 1 M HCl for 1 day. The SB was mainly comprised of cellulose, hemicelluloses, and lignin components [15], which can be dissolved or broken down during a pretreatment process [16]. Mosier et al [17] and Zheng et al [18] stated that diluted acid pretreatment process could dissolve almost all hemicelluloses and break down the bonds of cellulose and lignin.…”

The objective of this study was to assess the efficiency of a novel TiO2/modified sago bark (TiO2/MSB) mixture for the degradation of sago wastewater effluent by employing response surface methodology (RSM) using chemical oxygen demand (COD) removal as the target parameter. The highest COD removal of 64.92% was obtained using TiO2/MSB mixture sample prepared by combining 0.2 g/L TiO2and 1 w/w% MSB. Given that the highest removal was produced using this mixture sample, further optimisation of sago wastewater treatment was conducted by varying the independent variables, namely, dosage and contact time. Under this optimum condition, 0.10 g of 0.2 g/L TiO2/1% MSB had successfully reduced 52.83% COD in 120 min. Surface morphology, functional groups, and elemental analysis supported observations of the ability of TiO2/MSB mixture to remove COD. Additionally, aeration had further improved COD removal by 11%. The regression value (R2>0.99) of the model indicated a high degree of correlation between the evaluated parameters. These results proved the feasibility of TiO2photocatalysis as an appealing alternative protocol for sago wastewater treatment and solid waste from the industry can be utilised for wastewater degradation.

“…In the last decades, various pretreatment methods have been explored by researchers, such as dilute acid hydrolysis [12,13], alkaline pretreatment [12,14], autohydrolysis [15], steam explosion [12], ionic liquids pretreatment [16,17], and inorganic salt solution pretreatment [10,18]. Among these methods, pretreatment with inorganic salt solution is an outstanding and feasible means due to high efficiency and low cost [10,19].…”

Effect of Ni(NO3)2 Pretreatment on the Pyrolysis of Organsolv Lignin Derived from Corncob Residue

et al. 2020

The thermal degradation of lignin for value-added fuels and chemicals is important for environment improvement and sustainable development. The impact of pretreatment and catalysis of Ni(NO3)2 on the pyrolysis behavior of organsolv lignin were studied in the present work. Samples were pyrolyzed at 500 ∘C with an upward fixed bed, and the characteristics of bio-oil were determined. After pretreatment by Ni(NO3)2, the yield of monophenols increased from 23.3 wt.% to 30.2 wt.% in “Ni-washed” and decreased slightly from 23.3 wt.% to 20.3 wt.% in “Ni-unwashed”. Meanwhile, the selective formation of vinyl-monophenols was promoted in “Ni-unwashed”, which indicated that the existence of nickel species promoted the dehydration of C-OH and breakage of C-C in pyrolysis. In comparison with “Water”, HHV of bio-oil derived from “Ni-unwashed” slightly increased from 27.94 mJ/kg to 28.46 mJ/kg, suggesting that the lowering of oxygen content in bio-oil is associated with improved quality. Furthermore, the content of H2 in gas products dramatically increased from 2.0% to 7.6% and 17.1%, respectively.
