摘要/Abstract

摘要：

荻\[Triarrhena sacchariflora (Maxim.) Nakai\]是一种生产燃料乙醇的植物原料,深入研究有助于缓解石油危机问题。通过4个预处理条件的单因素试验,明确了处理后样品中纤维素、半纤维素、木质素三个指标含量的变化规律,再通过正交试验确定了荻制取燃料乙醇过程中稀硫酸预处理的最佳条件。研究结果表明效果最好的两个预处理条件是:①硫酸浓度:1.5%(g/mL),固液比:1∶6,时间:30 min,温度:120℃;纤维素含量提高15.28%。②1.5%,1∶8,15 min,120℃;纤维素含量提高15.11%。该结果为荻制取燃料乙醇提供了可靠的依据。

Abstract:

Triarrhena sacchariflora (Maxim.) Nakai could produce fuel ethanol. Further research about it could reduce petroleum crisis. The changing rule of the contents of cellulose, semi-cellulose and lignin in the samples after treatment were clarified via 4 single-factor experiments under pretreatment conditions. And optimum conditions of dilute sulfuric acid pretreatment for producing fuel ethanol from Triarrhena sacchariflora (Maxim.) Nakai were ensured through orthogonal experiment. The results show that the best 2 pretreatment conditions were: ① sulfuric acid concentration: 1.5% (g/mL), solid-liquid ratio: 1∶6, time: 30 min, temperature 120℃; cellulose content increased by 15.28%. ② 1.5%, 1∶8, 15 min, 120℃; cellulose content increased by 15.11%. These results have provided reliable basis for producing fuel ethanol from Triarrhena sacchariflora (Maxim.) Nakai.

Key words: Triarrhena sacchariflora (Maxim.) Nakai, fuel ethanol, sulfuric acid pretreatment, optimum condition
