Hot Water Pretreatment of Boreal Aspen Woodchips in a Pilot Scale Digester
Hot water extraction of aspen woodchips was treated at about 160 °C for 2 h with a liquor-to-solid ratio of 4.76:1 in a 1.84 m batch reactor with external liquor circulation. Both five-carbon and six-carbon sugars are obtained in the extraction liquor. Xylose and xylooligomers are the main five-carbon sugar in the hot water extract, which reached a maximum concentration of 0.016 mol/L, and 0.01...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
Methane Production from a Pilot-Scale Fixed-Film Anaerobic Digester and Plug-Flow Digester Loaded with High-Solids Dairy Manure
Three pilot-scale anaerobic digesters (two of a unique fixed-film design, of which one was fed micronutrients, one not, and an identically sized plug-flow digester, which served as the control) were monitored for methane production as a comparative indication of performance. All of these pilot-scale digesters were loaded daily with high-solids dairy manure, passed through a 1.5" x 3" mesh scree...
متن کاملImpact of fluid velocity on hot water only pretreatment of corn stover in a flowthrough reactor.
Flowthrough pretreatment with hot water only offers many promising features for advanced pretreatment of biomass, and a better understand- ing of the mechanisms responsible for flowthrough behavior could allow researchers to capitalize on key attributes while overcoming limitations. In this study, the effect of fluid velocity on the fate of total mass, hemicellulose, and lignin was evaluated fo...
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...
