Dilute Sulfuric Acid Pretreatment for Producing Fuel Ethanol from Triarrhena Sacchariflora (Maxim.) Nakai
摘要
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 Trianhena sacchariflora ( Maxim. ) Nakai were ensured through orthogonal experiment. The results showed 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 had provided reliable basis for producing fuel ethanol from Triarrhena sacchariflora ( Maxim. ) Nakai.关键词
