摘要: 采用热磨方法对玉米秸秆进行预处理,再经稀硫酸催化加压水解,制得玉米秸秆水解液。结果表明:以热磨预处理后的玉米秸秆为原料制得的水解液中还原糖浓度为 4%~5.5%,还原糖得率为 60%~75%,较未经预处理的玉米秸秆水解液还原糖得率提高约 50%。

Abstract: After hot grinding pretreatment of corn stalks, the hydrolysate of corn stalks by dilute sulfuric acid was prepared. The result shows that the concentration of reducing sugar in dilute acid hydrolysate from pretreated corn stalks was about 4%-5.5%. The yield of reducing sugar was up to 60%-75%, which is 50% higher than that from corn stalks un-pretreated.

Key words: corn stalk, hot grinding, dilute sulfuric acid, hydrolysis
