Abstract

Cellulose and the like are converted into sugar by heating under pressure at 120-220 DEG C. with batches of acid-reacting liquid which flow at intervals through the cellulose material, remove the sugar formed from the reaction chamber and leave the cellulose in wet, moist or semi-dry condition for treatment with the next batch of liquid. The cellulose material is compressed and the liquid is forced through the material by pressure steam or compressed gases. The batches of liquid may flow in countercurrent to the cellulose through a battery of hydrolysers connected in series. The hydrolysers taper towards the bottom to correspond with the shrinkage of the lignin cake. If the resulting sugar liquor is to be fermented, phosphoric acid, sulphurous acid and nitrogen compounds are added, and the pH value is brought to 5 to 6.
