Numerical simulation of microwave heating of petroleum coke (PC) was successfully predicted by COMSOL Multiphysics software version 5.2. The simulation is used to study how the temperature and electric field are distributed inside the domestic microwave oven. The simulation study was performed at a microwave input power of 500 W and time of 60 s. Numerical modelling has shown that an optimal temperature can be generated while heating a PC sample. The gradient temperatures of the PC sample change with a combination of cavity and the energy dissipated in the sample, an optimal temperature of which is 898 K. Moreover, a decrease in the electric field distribution was observed by conduction inside the PC sample. The results may provide a reference for the study of heating of PC by microwave energy.
