METHOD FOR PROCESSING A BIOMASS CONTAINING LIGNOCELLULOSE

There is disclosed a method for processing a biomass (for example straw) containing lignocellulose such that cellulose and hemicellulose are made accessible for further processing， typically by decomposition， without needing energy-consuming dissolution of the biomass in water. The method includes repeated compressions of the biomass in a reciprocating piston press， where loose biomass is continuously fed into a piston chamber in front of a piston which moves the loose biomass into a tubular reaction chamber in which the biomass is compressed for producing a vapour explosion and autohydrolysis under simultaneous displacement of compressed biomass through the reaction chamber. After compression， the biomass can be added fluid livestock manure， fluid waste water sludge etc. in a biogas plant for a subsequent biogas process.
