| 20110104773 | PROCESSING METHOD FOR FRACTIONALLY CONVERTING PENNISETUM HYDRIDUM INTO FUEL ETHANOL WITH CO-PRODUCTION OF ELECTRICITY GENERATION AND PAPER PULP - The invention relates to a method for fractionally converting pennisetum hydridum into fuel ethanol with co-production of electricity generation and paper pulp, which comprises subjecting the pennisetum hydridum having been cut into segments to steam explosion treatment by utilizing a steam explosion device to obtain a steam explosion product, and said method is characterized in that it comprises the steps of: washing the steam explosion product with water to obtain fibers and water washing liquid containing a degraded hemicellulose, and separating and purifying the water washing liquid to obtain an xylo-oligosaccharide; fractionally teasing the fibers, and subjecting the obtained long fibers to an ethanol self-catalyzed pulping and then a bleaching treatment to obtain a paper pulp, and after recovering ethanol, obtaining an alcohol-soluble lignin by separation; preparing cellulase by a solid state fermentation, that is, taking the short fibers obtained by fractionally teasing as a fermentation substrate of | 05-05-2011 |
