Abstract

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.
