Abstract The invention relates to a process for refining a biomass from empty fruit bunches of oil palm with a dry matter content of 5-95 wt.%, based on the total wt. of the biomass, where the process comprises the subsequent stages of (a) water extn. under atm. pressure conditions and at pH of 5-7, (b) pre hydrolysis with water, steam or a their mixt. at 100°- 200°, and (c) hydrolysis at a pH of <7. In a further aspect of the invention, one or more valuable byproducts such as for example, vegetable oil, hemicellulose, lignin, furans, org. acids and monomeric and/or polymeric sugars are recovered from the refining process. The present invention also relates to a dissolving pulp obtained by the process according to the invention, and to the use of the dissolving pulp for the prodn. of cellulose acetate.
