Abstract
An effective pretreatment with the combined treatment of various chemical reagents and steam explosion on rice straw is determined: rice straw and 3% NaOH(W/V is 1∶5),blending,holding at 126~128 ℃,insulation five minutes,gas discharge.75.58 % lignin in the straw can be removed by this pretreatment;enzymatic hydrolysis of rice straw(enzymatic hydrolysis conditions:2% substrate,0.2% cellulose,pH4.8,0.2mol/L HAc-NaAc buffer solution,temperature 46℃,hydrolysis 48h) reaches to 91.98%
