Microwave-assisted Carbochlorination Recovery of Indium Process of Dynamic Simulation Based on Multi-Field Coupling

The microwave-assisted carbochlorination process of InClsub>3 recovery in the microwave reactor cavity of the laboratory was obtained by the multi-field coupling simulation and analysis was conducted on the influenced factors based on the finite element method software of COMSOL Mutiphysics. Combined microwave heating process, computational fluid dynamics and mass transport process, a mathematical-physical model coupled of four physics fields was established, composed of radio frequency, heat transfer, mass transport and flow field. Then further researches on the electric field of the cavity were carried out. It is concluded heat source of microwave heating process and temperature distribution of samples, indicated that the research model can accurately describe the influence on the process of indium recovery from the microwave input power and HCl concentration as well. It is a new method and an evidence for microwave-assisted carbochlorination recovery of indium process analysis.
