Methane produced by corn stalk anaerobic fermentation under different dosage of NaOH

摘要

With crisis of coal, oil and natural gas and other fossil energy, people gradually turned to biomass energy, the preparation of methane is of great practical significance. Different alkali pretreatment can affect the anaerobic fermentation of corn stalk system. NaOH as pretreatment agent was added into corn straw in different dosage and different organic loading rate. The corn straws were dealed with NaOH at different dosage. The results are shown as follows: Compared with corn straw without NaOH pretreatment, gas amount per day, the cumulative gas amount and the amount of methane has greatly improved, where optimum pretreatment agent was 2% NaOH.
