    Description

    Work in progress on prehydrolysis of white birch (Betula papyrifera) wood with sulfur dioxide presents an alternative means for producing a relatively concentrated pentose solution with a very small requirement for steam or other forms of energy. The key ideas are to conduct the prehydrolysis reaction at a very low liquor-to-wood ratio (called vapor-phase cooking in the pulp industry) and to obtain a relatively concentrated solution by countercurrently extracting the xylose, xylose oligomers, and other solubilized material from the reacted chips.
