Abrégé

The invention relates to a method for obtaining cellulose fibres from fibrous biomass, in which: the biomass is first subjected to thermo-pressure hydrolysis, preferably with steam explosion, in a thermo-pressure hydrolysis plant, and then separation of the fibrous sludge obtained from the thermo-pressure hydrolysis plant is carried out in at least one separation plant, wherein a press cake of cellulose fibres, preferably with a dry material content of over 20%, preferably of over 25%, and a filtrate of flowable, solids-rich thin sludge are obtained, and wherein the thin sludge is fed to a biogas plant as a fermentation substrate to obtain biogas. The invention also relates to a plant for carrying out this method.

Abrégé

The invention relates to a device for the hydrolysis of preferably solid organic substrates, in particular of energy crops and plant residues, with a collection vessel (1) for receiving the organic substrates, with a conveying means (4) for transporting the organic substrates into a charging device (7) for the batch-wise charging of a hydrolyzer (10) with the organic substrates, the hydrolyzer (10) being provided on the output with a pressure-release device (12) having a valve-controlled pressure diaphragm (13) and a steam trap (14) arranged upstream of an expander tank (15). According to the invention, the conveying means (4) includes a conveyor worm (4′) with a sleeve shaft (25), which is charged with hot steam from the steam trap (14), which is preferably designed as a cyclone, the sleeve shaft (25), in the conveying zone for the organic substrate, having, in a heating zone (18), steam-outlet openings (26) for directly charging the organic substrate with hot steam.
