    • The semi-continuous process according to the invention for hydrolyzing cellulose-containing material (substrate) with gaseous hydrogen fluoride comprises sorption and subsequent desorption of HF in a total of n steps. The substrate is divided into n batches in n reactors (1a, 1b, 1c, . . . ); each batch passes through the n process steps in one reactor (1a, . . . ). Initially, sorption is carried out in the first to the (n/2)th step by the action of HF-inert gas mixtures, having an HF concentration which increases from sorption step to sorption step, at a temperature above the boiling point of HF. Subsequently, desorption is brought about in the ((n/2)+1)th to nth step by treating with heated HF-inert gas mixtures having an HF concentration which decreases from desorption step to desorption step; n is an even number from 4 to 12 and the n steps each take place in the same time segments (periods). The sequence of steps is displaced by one period from each batch to the next batch. During each period, the batch in the first step is connected to the batch in the last step and the batch in the second step with the batch in the penultimate step and the batch in the (n/2)th step with the batch in the ((n/2)+1)th step, by HF-inert gas circulations.

    • A continuous process for hydrolyzing cellulose-containing material (substrate) with gaseous hydrogen fluoride, HF is sorbed by the substrate at a temperature above its boiling point in n sorption steps and thereafter the sorbed HF is removed from the substrate by heating in n desorption steps. The number n of sorption steps and of desorption steps is identical and the reaction steps mentioned each occur in reactors which are separated from one another in a gas-tight manner. After introduction into the first sorption reactor (1a), the substrate passes consecutively through gas-tight valves into the second (1a) . . . nth sorption reactor and from the latter, optionally via a hold-up reactor (2) into the first, second, . . . nth desorption reactor (3a) and is removed from the nth desorption reactor (3a). The streams of HF gas, which contain an inert carrier gas in addition to HF, are circulated between the first (1a) or second (1b) or . . . (n-1)th or nth sorption reactor and the nth (3a) or (n-1)th (3b) . . . or second or first desorption reactor respectively.
