<p>There is disclosed a process for producing paper-making pulps form grasses. The process comprises impregnating a grass in the form of chips with a 0.5 to 6% by weight aqueous solution of alkali at a temperature of 10 to 100.degree.C., compressing the grass to remove an excess aqueous solution so as to provide a wet mass of grass, loosening the wet mass to provide a porous mass of grass, treating the porous mass with an oxygen-containing gas at a temperature of from about 60.degree.C to about 130.degree.C., and then washing the resulting pulp with water and drying it.</p> |
