主　　题：microwave depolymerization numerical simulation kraft lignin COMSOL Multiphysics 

摘      要：Kraft lignin has the potential to replace traditional fossil resources for the preparation of high-value chemicals because it is rich in aromatic rings and active functional *** effective method for the pyrolysis of kraft lignin into chemicals/fuels is microwave-assisted depolymerization.A simulation model is urgently needed to illustrate the coupling effect and mechanism of lignin conversion during the depolymerization *** this study,COMSOL Multiphysics was used to simulate the microwave-assisted depolymerization *** results showed that microwave power had a significant effect on the electric field and temperature distribution in the microwave cavity,while the reaction time had little effect on the electric *** effect of the nitrogen flow rate on the electric field and temperature was *** intensity of the electric field,heating rate of lignin,and final temperature of lignin depolymerization increased with increasing microwave power.
