Title:
PRETREATMENT PROCESS PERFORMED AT ROOM TEMPERATURE FOR PURPOSE OF RECOVERING FERMENTABLE SUGARS FROM BIOMASS INCLUDING CHESTNUT SHELL, AND BIOREFINERY PROCESS COMPRISING PRETREATMENT PROCESS
Document Type and Number:
WIPO Patent Application WO/2024/019577
Kind Code:
A1
Abstract:
The present invention relates to: a pretreatment process performed at room temperature for the purpose of recovering fermentable sugars from biomass including chestnut shell; and a biorefinery process comprising the pretreatment process, and, to optimal conditions of a pretreatment process under which the pretreatment process is carried out at room temperature so that energy efficiency and the recovery rate of fermentable sugars are maximized.
