Sugarcane bagasse (SCB) was pretreated with 1-butyl-3-methylimidazolium chloride (BmimCl) at different conditions of temperature (80 °C to 150 °C) and solid loading (4 to 10%) at two times (20 and 60 min). The pretreatment conditions were optimized using a central composite rotatable design (CCRD) and desirability function having in mind the principles of green engineering. The pretreatments resulted in modifications of morphological and structural characteristics of biomass, also resulting in partial hemicellulose reduction. The founded optimal condition of pretreatment under the criterion of maximized sugar yield after enzymatic hydrolysis and minimized total sugar loss in pretreatment was 140 °C and 6% w/w of solid loading with 20 min of process. Also, a kinetic model was obtained verifying its validity with experimental values. It showed a lower activation energy of cellulose modification and hemicellulose conversion in comparison with the literature. One of the major findings was the strong correlation between glucose conversion and the degree of polymerization.

甘蔗渣（SCB）用1-丁基-3-甲基咪唑鎓氯化物（BmimCl）在不同的温度条件（80°C至150°C）和固体负载量（4％至10％）下进行了两次预处理（20和60分钟） ）。考虑到绿色工程原理，使用中央复合可旋转设计（CCRD）和合意功能对预处理条件进行了优化。预处理导致生物质的形态和结构特征的改变，还导致半纤维素的部分还原。在酶水解后糖产量最大化和预处理中总糖损失最小的准则下，确定的最佳预处理条件是140°C和6％w / w的固体负载（处理20分钟）。另外，获得了动力学模型，用实验值验证了其有效性。与文献相比，它显示出较低的纤维素改性和半纤维素转化的活化能。主要发现之一是葡萄糖转化率与聚合度之间的强相关性。
