NON-PRESSURISED PRE-TREATMENT, ENZYMATIC HYDROLYSIS AND FERMENTATION OF WASTE FRACTIONS

摘要

THE PRESENT INVENTION RELATES TO A PROCESS FOR PRODUCTION OF FERMENTATION PRODUCTS, INCLUDING BIOETHANOL BY NON-PRASSURISED PRE-TREATMENT, ENZYMATIC HYDROLYSIS AND FENNENTATION OF WASTE FRACTIONS CONTAINING MONO- AND/OR POLYSACCHARIDES, HAVING A RELATIVELY HIGH DRY MATTER CONTENT. THE PROCESS IN ITS ENTIRETY, I.E. FROM NON-PRESSURISED PRE-TREATMENT OVER ENZYMATIC HYDROLYSIS AND FERMENTATION TO SORTING OF FERMENTABLE AND NON-FERMENTABLE SOLIDS CAN BE PROCESSED AT A RELATIVELY HIGH DRY MATTER CONTENT IN A SINGLE VESSEL OR SIMILAR DEVICE USING FREE FALL MIXING FOR THE MECHANICAL PROCESSING OF THE WASTE FRACTION.
