摘要： The invention relates to a method and an equipment for the processing of lignocellulose materials by continuous pressure hydrolysis, optionally in the presence of inorganic acid, by consequent expansion and separation of the hydrolysate and gaseous phase, wherein disintegrated raw material is wetted (50, 52, 67, 69) by pressure water of the temperature 170 to 200 DEG C at the ratio water to dry matter 0.5 to 1:1, from the mixture obtained excessive water is removed by pressing (51) to the ratio of dry matter to water 1:0.3 to 0.5, consequently with simultaneous feed of pressure water of the temperature 170 to 200 DEG C in the ratio to dry matter 1:2.5 to 4 it is hydrolysed at the temperature 160 to 230 DEG C and pressure 0.6 to 2.8 MPa for 3 to 18 minutes, while hydrolysis proceeds with simultaneous uniform advancement (54) of solid and liquid phases, after termination of hydrolysis the material is expanded in two stages (56, 57) giving rise to gaseous phase (2, 3) and hydrolysate (62), gaseous phase contains furfural, methanol and acetic acid, hydrolysate contains cellulose, lignin and water, gaseous phase is rectified (59) and separated to furfural (7) mixture and mixture of acetic acid, formic acid and water (8), water is removed from hydrolysate by pressing (64) and solid remnant (11) is extracted (66) by solvent from group formed by ethanol or acetone, lignin is extracted to the solvent and after evaporation of the solvent reactive lignin is obtained, cellulose remains in solid phase, furfural obtained from the gaseous phase is purified by other distillation and pure furfural may be further treated to furane.
