Hot Water Extraction of Hemicelluloses from Aspen Wood Chips of Different Sizes
Hot water extraction of hemicelluloses from aspen wood chips of different sizes and wood meal was performed, and the extracted hemicelluloses were characterized. With decreasing wood chip size, the total sugars and total polyand oligosaccharides extracted with hot water increased. The dissolution of hemicelluloses was mainly limited by diffusion in the fiber wall and mass transfer from fiber to...
متن کاملREMOVAL OF HEMICELLULOSES BY NaOH PRE-EXTRACTION FROM ASPEN CHIPS PRIOR TO MECHANICAL PULPING
Hemicelluloses can be removed from wood chips prior to mechanical pulping, which would offer new feedstocks for the production of chemicals and fuels. The aim of this study was to evaluate pre-extraction to maximize pre-extraction yield, while minimizing negative impacts on wood chips. The effects of three independent process variables (NaOH charge, pre-extraction temperature, and time) on thre...
متن کاملDegradation and Redeposition of the Chemical Components of Aspen Wood during Hot Water Extraction
Hot water extraction (HWE) prior to pulping of wood is a promising method in constructing a platform for traditional pulping or for biorefinery processing. In this study, HWE of aspen wood at a maximum reaction temperature (Treaction) between 140 and 180 oC was investigated to obtain an optimal extraction condition for wood-derived products. The effect of extraction temperature and reaction tim...
متن کاملHot-water Extraction of Ground Spruce Wood of Different Particle Size
Hot-water extraction of hemicelluloses, especially galactoglucomannans, from fractions of ground spruce wood with different particle sizes was studied at 170°C with extraction times up to 60 min. Extraction of spruce sapwood, heartwood, and thermomechanical pulp (TMP) was also compared at 160 to 180°C. Static batch extractions were carried out in an accelerated solvent extractor (ASE). The extr...
متن کاملHydrolysis of sweet sorghum bagasse and eucalyptus wood chips with liquid hot water.
The chemical composition, hydrolysis products, and kinetics during liquid hot water pretreatment of sweet sorghum bagasse (SSB) and eucalyptus wood chips (EWC) were investigated. Under optimal conditions, a total xylose recovery of 79.6% and 55.6% for SSB and of 74.9% and 84.4% for EWC was achieved after pretreatments in a step-change flow rate reactor (184 °C, 20 ml/min, 8 min, and 10 ml/min, ...
