资源简介：
In alternative embodiments， provided are methods and industrial processes for generating pulp from lignocellulosic feedstocks， comprising directly contacting a lignocellulosic feedstock with a system comprising a super critical or sub-super critical fluid or mixture of fluids， whereby the partial pressure of the system provides for the hydrolysis or a combination thereof of the feedstock at reduced temperatures and pressures， followed by an upgrading step wherein a low-purity cellulosic material generated in the super critical or sub-super critical reaction step is treated with an alkaline solution. In alternative embodiments， provided are systems and methods for producing a cellulose material using reduced amounts of water.
