摘要：
This work focused on the effect of NH4Cl on pretreatment of eucalyptus for xylose recovery rate. Response surface methodology (RSM) was applied to design the experiments, and the optimum pretreatment conditions were determined, resulting in 77.45% xylose recovery rate. A quadratic polynomial equation for predicting the xylose recovery rate was developed. The experimental results were in good agreement with predicted values. Composition analysis proved that NH4Cl pretreatment had a good effect on hemicellulose in eucalyptus, and the physical surface of the eucalyptus showed an apparently damaged surface after pretreatment with NH4Cl in scanning electron microscopy (SEM) images.
