资源简介：
A process for hydrolyzing lignocellulosic biomass includes feeding lignocellulosic biomass into a pretreatment reactor， wherein the pretreatment reactor has a headspace charged with sulfur dioxide previously used in the pretreatment of lignocellulosic biomass. In addition， acid comprising sulfur dioxide and/or sulfurous acid is fed into the pretreatment reactor (e.g.， with the lignocellulosic biomass， separate from the lignocellulosic biomass， or a combination thereof) and the lignocellulosic biomass is heated. As the pretreated lignocellulosic biomass is discharged from the pretreatment reactor， at least a portion of the sulfur dioxide used in the pretreatment is retained in the headspace.
