摘要
采用高压湿氧冲爆技术对粉渣原料进行预处理,利用单因素和正交实验优化预处理条件,得到最佳的预处理条件为温度210℃,氧气压力1.2MPa,液固比3:1,保温时间10min。预处理后的原料松弛度提高,比表面积升高至0.298m2/g,变为原来的12倍,从而提高了原料中纤维素的转化率。
Pretreatment residue by the technology of steam explosion which was in high levels of oxygen and steam.We optimized treatment＇s conditions by means of experiments.The optimum treatment＇s conditions were obtained：the treatment＇s temperature was 210℃;oxygen＇s pressure was 1.2MPa;liquid-solid ratio was 3：1;heat preservation＇s time was 10min.Then,we could get a high-fraction void residue whose specific surface area was 0.298m2/g and 12 times than before.Thereby,we could improve the percent conversion of cellulose in residue.
