Abstract
A method for preparing dispersant using lignin degradation products includes preparation of lignin degradation products: degrading lignin which are used as raw materials using alkali through microwave-assisted activation at the presence of a metal oxide catalyst to obtain the lignin degradation products; and preparation of dispersant: preparing dispersant by molecularly reforming and chemically modifying the lignin degradation products obtained in the step of preparation of lignin degradation products.
