Stalk is a renewable resource. The mainly methods on hydrolysis of cellulose from stalk are using cellulase and acid. It is a hot potato how can improve the rate of enzymatic hydrolysis on cellulose in the world. It becomes important to combinatorial optimization and operating cost reduction.
Three different pretreatment methods were tested to study the effect on hydrolysis of cellulose from corn stalk. The dilute-acid、dilute-alkali and sodium sulfite anhydrous pretreatment of corn stalk were carried ou...
