摘要：

In this paper，COMSOL is used to calculate and analyze three influencing factors of microwave pyrolysis. The results show thatthe maximum difference in average temperature is more than 50%，and the maximum microwave energy absorption efficiency is 92% under the calculation conditions. Adding akindoftypical absorbent agentcarbon spheres can improve the energy absorption efficiency of biomass，resulting in the average temperature of biomassincreasing，and the energy efficiency can be increased by 5% at most. The temperature uniformity of biomass can be optimized by adding rotation speed，the maximum temperature standard deviation difference between with and without rotation speed is about 26%. However，the rotation speed has little effect on the temperature uniformity. © 2023 Science Press. All rights reserved.
