Zusammenfassung:A method for acid-catalyzed hydrolytic splitting of cellulose to give a high yield in sugar with a minimal expenditure in energy, in particular, with the smallest possible charge of live steam. Admission of steam is performed in a plurality of successive, discrete reaction stages having in each case defined temperature and pressure values in such a manner that the temperature rises from one stage to the next while the reaction time decreases and a rapid expansion takes place subsequently to the last reaction stage. A high pressure poured bed reactor is used for performing this method.
