text: The polysaccharides and derivatives thereof may be used as raw materials either alone or in a combination of two or more.
text: The purpose of the present inven-tion is continuous decomposition of the polysaccharides contained in a raw material into different products, and this purpose is achieved by means of the method in accordance with the invention, which is mainly characterized in that the raw material that contains poly-saccharides is hydrolyzed continuously in one reactor as two steps so that, in the firs-t step, the hydrolysis is run in the upper part of the reactor in a vapour phase by the effect of strong acid and water vapour, whereby the pentosans are de-composed mainly into furfural, acetic acid, methanol, and acetone, and the hexosans are decomposed into disaccharides and trisaccharides, and in the second step -the hydrolysis is run in the bottom part of the reactor in a li.quid phase by the effect of dilute acid and water vapour, whereby -the disaccharides and trisaccharides obtained in the first step are decomposed into monosaccharides and into saccharic and fa-tty acids.
