微波辅助稻草预处理提取纤维素实验条件研究

Study on Extract Conditions of Cellulose from Straw Pretreatment with Microwave Assisted

以稻草秸秆作为纤维素原料,将微波加热应用于稻草秸秆的预处理过程中,考察了微波功率和作用时间对实验结果的影响。结果表明,用10g/L NaOH溶液预处理并在微波中火辅助加热的条件下,当3%H_2O_2溶液、0.5%NaOH溶液和0.5%H_2SO_4溶液处理40 min后,纤维素收率最高,达60.39%。

As the raw cellulose material, the microwave heating was used for the pretreatment process of rice straw. The influences of the reaction power and time of microwave heating on rice straw were investigated. After the pretreatment by 10 g/L NaOH and the microwave auxiliary heating, treatment with 3% H202, 0. 5% NaOH and 0. 5% H2SO4 with 40 min, and the cellulose yield was 60.39% , which was the best case.
