Abstract

In the production of sugars from materials containing cellulose, lignin and hemicellulose, e.g. wood, bagasse, cotton stalks, the material in particles of size 0.3-1.5 mm. is treated with 29-36% aqueous hydrochloric acid, a concentration sufficient for hydrolysis of the hemicellulose but not for hydrolysis of the cellulose and the lignin, and the liquid containing the hydrolysed hemicellulose is removed from contact with the residue of the material. The residue may then be treated with more highly concentrated aqueous hydrochloric acid for hydrolysis of cellulose and lignin, the liquid being again separated from the residue.
