Abstract

169,802. Enge, L. July 3, 1920. Pulp, preparation of. - In the preparation of light coloured strong fibrous material for the paper trade from wood, or other substance containing cellulose, in logs or billets, the material is saturated, softened, or boiled with water in vacuum or under mechanically produced water, air, or steam pressure. Either a high temperature of 105‹-120‹ C., or a low temperature of about 80‹ C., and a high pressure of from 5 to 10 atmospheres or a low pressure of about 350 m.m. of mercury may be employed. Neutral, acid, or alkali reagents may be added to the water. A flowing movement of the liquid used is maintained in the direction parallel to the direction of the fibres of the wood. When treating under vacuum, an air-pump is used during the whole operation lasting 6-8 hours, the drop in temperature being made up by indirect heating.
