  • Process for the production of xylose
    Patent number: 5340403
    Abstract: A process for producing xylose from a ligno-cellulosic material comprising xylan-containing hemicellulose in which the ligno-cellulosic material is subjected initially to the three steps (1) hydrolysis to produce an aqueous xylose-containing medium and an insoluble residue; (2) separation of the insoluble residue from the medium; and (3) treatment of the medium to remove organic and/or inorganic nutrients therefrom. The medium is thereafter concentrated to a syrup having a water content in the range 20% to 40% by weight which is then mixed with ethanol and the xylose is separated from the ethanolic solution.
