资源简介：
A process for producing a fuel from lignocellulosic biomass is disclosed. The process includes obtaining a feedstock comprising lignocellulosic biomass， pretreating a slurry containing the lignocellulosic feedstock， sulfur dioxide， and optionally a bisulfite salt， at temperatures between 110°C and 160°C for at least 30 minutes. The pretreatment includes subjecting the slurry to a pH adjustment， which includes adding alkali to the slurry， removing lignosulfonic acid from the slurry， or a combination thereof.
