“…The results obtained by applying the hydrothermal pretreatment were similar to those obtained for other biomass such as grape stalks, corn stalks, grass (Cynodon dactylon), sorghum, wood, olive tree prunings, eucalyptus, bamboo, wheat straw and sugarcane bagasse (Amendola et al, 2012;Egues et al, 2012;Lee et al, 2009;Rohowsky et al, 2013;Chen et al, 2010;Martin et al, 2010;Alves et al, 2010;Ruiz et al, 2013a;Ruiz et al, 2013b;Abril et al, 2012). Figure 2 shows the results of the morphological analysis of the raw material and solid fraction of the pretreated bagasse by SEM.…”

-Glucose production from sugarcane bagasse was investigated. Sugarcane bagasse was pretreated by four different methods: combined acid and alkaline, combined hydrothermal and alkaline, alkaline, and peroxide pretreatment. The raw material and the solid fraction of the pretreated bagasse were characterized according to the composition, SEM, X-ray and FTIR analysis. Glucose production after enzymatic hydrolysis of the pretreated bagasse was also evaluated. All these results were used to develop relationships between these parameters to understand better and improve this process. The results showed that the alkaline pretreatment, using sodium hydroxide, was able to reduce the amount of lignin in the sugarcane bagasse, leading to a better performance in glucose production after the pretreatment process and enzymatic hydrolysis. A good xylose production was also observed.

“…The total mass balance in these varied materials is the summative analysis of the carbohydrates disclosure into their derivatives together with lignin, extractives, and ash contribution [6][7][8]. Therefore, a chemical analysis including determination of the dry matter, elements composition and contents of ash, glucan, xylan, mannan and lignin was performed.…”

Abstract. In pulp and paper industry biomass rich in energy is represented by pulping liquors, wood wastes, sludge and rejects. Many pulp and paper mills produce more than half of their energy needs from biomass fuels recovered from solid pulp and paper wastes. The end-products of conversion of these wastes are solid, liquid or gaseous fuels and moreover, in most cases, the valuable and ecological fertilizer. The proper method of biomass conversion depends on its structure and chemical composition, which includes hemicellulose, cellulose and lignin content.. Pulp and paper industry generate a lot of quantities of valuable biomass as wastes in all stages of the process. Therefore, this paper reviews the current state of using waste from pulp and paper industry as a fuel for energy purposes. For investigation, the materials from four different types of pulp waste were used. Pulp waste I contained knots and barks and was a product of chemical and semi-chemical pulp processes and of mechanical pulp manufacture, pulp waste II contained final fiber waste sludge from kraft mill, pulp waste III contained fiber sludge from board mill and pulp waste IV contained final fiber waste sludge from board mill. The article contains a description of physical properties of pulp wastes such as: moisture content, density, gross and net calorific values. A chemical analysis includes determination of dry matter, element composition and contents of ash, glucan, xylan, mannan and lignin. It was found that residues from mechanical and chemical pulping varied in the origin and stage of production, had similar chemical composition, differed in a narrow range. Pulp waste materials are rich in sugars of above 52 %, reaching a value of approximately 71 %, depending on the sample taken at different stages of processing.Net calorific values for all tested raw materials were high in the range from 19.8 to 20.5 MJ·kg -1 and should be considered as feedstock suitable to generate enough energy.

“…In addition to traditional and standard methods of chemical analysis of lignocellulosics, APS were analyzed for their carbohydrate composition by 1 H-NMR analysis of acid hydrolysate [29][30][31]. The spectrum showing the distinct peaks of glucose, xylose, galactose, rhamnose, mannose, furfural, and acetate is presented in Figure 1.…”

Chemical Composition of Apricot Pit Shells and Effect of Hot-Water Extraction

et al. 2015

Abstract:Agricultural residues, such as corn stover, wheat straw, and nut shells show promise as feedstocks for lignocellulosic biorefinery due to their relatively high polysaccharide content and low or no nutritional value for human consumption. Apricot pit shells (APS) were studied in this work to assess their potential for use in a biorefinery. Hot water extraction (HWE; 160 °C, 2 h), proposed to remove easily accessible hemicelluloses, was performed to evaluate the susceptibility of APS to this mild pretreatment process. The chemical composition of APS before and after HWE (EAPS) was analyzed by standard methods and 1 H-NMR. A low yield of the remaining HW-extracted APS (~59%) indicated that APS are highly susceptible to this pretreatment method. activity (AOA) of APS extracts was also undertaken. AOA of organic APS extracts were shown to be more than 20 times higher than that of a synthetic antioxidizing agent.
