Laccase treatment is a promising approach to remove lignin from prehydrolysis liquor (PHL) for value added utilization of hemicellulose rich waste streams. Modeling the lignin removal process is of practical interest for prediction and control of laccase treatment of PHL. The present study focused on the lignin removal through variation of laccase charge and treatment time. Results showed that the lignin removal may be divided into two phases, i.e. a fast initial phase followed by a second slow phase. A kinetic model based on the experimental results was developed, which can be used to predict the lignin removal of PHL during the laccase treatment.
漆酶处理是一种很有前途的方法，可以去除预处理液（PHL）中的木质素，从而实现富含半纤维素的废物的增值利用。对木质素去除过程进行建模对于预测和控制 PHL 的漆酶处理具有实际意义。本研究重点研究了通过改变漆酶电荷量和处理时间来去除木质素。结果表明，木质素去除可分为两个阶段，即快速初始阶段和随后的第二缓慢阶段。基于实验结果开发了一个动力学模型，可用于预测漆酶处理过程中 PHL 的木质素去除。
