Abstract

As a renewable energy, ethanol from lignocellulosic biomass has developed technologically in many ways. Effective pretreatment can enhance the enzymatic saccharification of cellulose by removing lignin and hemicellulose from raw material. Different alkaline pretreatment technologies were studied to find more effective and economical pretreatment of rice straw for ethanol production. Results showed that heated ammonia pretreatment was more effectively to remove lignin than hemicellulose. Combination of microwaves and heated ammonia enhanced the removal of lignin and enzymatic saccharification. Besides of lignin and hemicellulose, lime pretreatment removed cellulose as well, that decreased the enzymatic saccharification. Take enzymatic saccharification and weight loss into concern, 2% NaOH pretreatment at 100 is the most effective alkaline pretreatment technology of rice straw for ethanol production.
