PROCESS FOR PRODUCING SUGARS BY ENZYMATIC HYDROLYSIS OF PRETREATED EFB OIL PALM WASTE

摘要

The invention relates to a process for preparing pretreated EFB oil palm waste for enzymatic hydrolysis and makes it possible to enhance the enzymatic hydrolysis of polysaccharides in the waste into soluble sugars. The method is intended for producing solutions of carbohydrates for the purpose of converting same into ethanol or other products of microbiological synthesis by further saccharification and combined fermentation. Empty Fruit Bunches, a waste product of oil palm (Elaeis guineensis) which is usually left after the production of palm oil, are preferably used as the initial feedstock. The method is based on eliminating the interfering influence of biogenic silicon dioxide and polyphenols and also gradually enhancing the reactivity of the polysaccharides in the raw material by alternating mechanical activation and enzymatic hydrolysis.
