In this study, we investigated some pretreatment methods of rice hull for enzymatic hydrolysis. Results were followed as:
1. Some chemical pretreatment methods were investigated, dilute acid, dilute NaOH, Ca(OH)_2, ammonia liquor and H_2O_2 were used to pretreated rice hull in the normal temperature and pressure. Results shown that effects of these methods were as follow: NaOH > dilute acid > Ca(OH)_2 > ammonia liquor > H_2O_2. Pretreatment of NaOH (1.5%, 6 h) led to 29.6% of net yields of total...
