“…3). Similar results were obtained by Fu and Mazza (2011), who purified wheat rye straw using an ionic liquid. The use of 1-ethyl-3-methylimidazolium acetate improved the yield of reducing sugars by 81% after enzymatic hydrolysis as compared to the control sample.…”

A b s t r a c t. In recent years, much attention has been devoted to the possibility of using lignocellulosic biomass for energy. Bioethanol is a promising substitute for conventional fossil fuels and can be produced from straw and wood biomass. Therefore, the aim of this paper was to investigate the effect of 1-ethyl-3-methylimidazolium pretreatment on the structure of cellulose and the acquisition of reducing sugars and bioethanol from cellulosic materials. Material used in the study was rye straw and microcrystalline cellulose subjected to ionic liquid 1-ethyl-3-methylimidazolium pretreatment. The morphology of cellulose fibres in rye straw and microcrystalline cellulose was imaged prior to and after ionic liquid pretreatment. Solutions of ionic liquid-treated and untreated cellulosic materials were subjected to enzymatic hydrolysis in order to obtain reducing sugars, which constituted a substrate for alcoholic fermentation. An influence of the ionic liquid on the cellulose structure, accumulation of reducing sugars in the process of hydrolysis of this material, and an increase in ethanol amount after fermentation was observed. The ionic liquid did not affect cellulolytic enzymes negatively and did not inhibit yeast activity. The amount of reducing sugars and ethyl alcohol was higher in samples purified with 1-ethyl-3-methylimidazolium acetate. A change in the supramolecular structure of cellulose induced by the ionic liquid was also observed.

“…The effect of pH value (Zhang et al 2013), particle sizes (Bahcegul et al 2012;Hou et al 2013), water content, pretreatment time, and other influencing factors (Brandt et al 2011) have been investigated in grasses, hardwood, and softwood. The impact of ILs treatment on the composition of treated biomass was investigated in several studies (Fu et al 2010(Fu et al , 2011). An advantage of ILs pretreatment could be the recovery of a separate lignin fraction, which could be converted to value-added chemicals, such as phenols, cresols, substituted phenols, etc.…”

Bamboo (Phyllostachys edulis) samples pretreated with ionic liquid (ILs)-H2O mixtures were studied concerning their application in the pyrolysis process.[Bmim]Cl-H2O, [Bmim]BF4-H2O, [Bmim]HSO4-H2O, and [Bmim]Ac-H2O mixture systems were used in the pretreatment process. The characteristics of pretreated bamboo were analyzed, as was cellulose extracted from ILs-H2O pretreated bamboo. The enrichment of cellulose (α-cellulose) in pretreated bamboo was achieved. The amount of char resulting from the pyrolysis of the [Bmim]Ac-H2O pretreated sample (20.1 wt%) was lower than the untreated bamboo sample (24.2 wt%) at 900 °C. A greater proportion of the pretreated bamboo samples was converted into gas products and/or liquids. The pretreated cellulose pyrolysis process could proceed more easily than processing untreated samples due to the disordered crystalline cellulose structure and the decrease in molecular weight.

“…1C, the ammonium sorption efficiency in wastewater was lower than the other systems with an adsorbing materials dosage of 20 g/L for 8 h. This result was due to the impact of various cations in the wastewater, which affected NH4 + removal by the adsorbing materials (Lee et al 2009;Fu and Mazza 2011). In wastewater, the concentration of major competing cations ranged from 13.18 mg/L to 133.09 mg/L (Table 3).…”

Corn stalks were modified by magnesium loading and an oxidation process and then characterized by a series of methods. The ammonium in wastewater showed high sorption efficiency onto the polymeric adsorbing material during the process, with a biochars dosage of 20 g/L for 8h. Mg 2+ was the dominant cation exchanger on the modified corn stalk, and it played an important role in ammonium sorption. Large amounts of NH4 + were exchanged onto the corn stalk, and they formed strong complexes with oxygen-containing groups on the corn stalk surface through polar bonds, resulting in the removal of NH4 + from the solution. Na + present in wastewater was the major influence on ammonium sorption onto the corn stalk.
