Pretreatment of Ligno-Cellulosic Biomass with Sulfonation |
| abstract |
Provided are methods for the pretreatment of ligno-cellulosic biomass such as softwoods with bisulfite such as ammonium bisulfite without the need for exogenous acid. In one variation, a method of pretreating ligno-cellulosic biomass is provided including the following steps: a) providing ligno-cellulosic biomass; b) contacting the ligno-cellulosic biomass with a solution comprising bisulfite at an amount between 1 and 10% of a dry weight of the ligno-cellulosic biomass to form a slurry; c) heating the slurry to a first temperature of 150-210° C. for a first period of time to form a first mixture; d) cooling the first mixture to a second temperature of 100-200° C. to form a second mixture; and e) maintaining the second mixture at the second temperature for a second period of time to form pretreated ligno-cellulosic biomass; wherein the first temperature is higher than the second temperature. |
