Modeling catalytic carbon dioxide methanation reactor heated by electromagnetic induction
The electromagnetic induction heating technology,as a new non-contact energy supply technology,can be used for heating reactors.This technology is expected to convert chemical production from fossil fuel-driven to electric energy-driven,effectively reducing carbon emissions.In this work,a modeling study on the electromagnetic induction heating of a carbon dioxide methanation reactor was conducted.A COMSOL Multiphysics model was established for the application of electromagnetic induction heating,and five coil winding modes,y=An,y=Bn2,y=Cn3,y=Den and y=E were designed.The effects of coil winding method and process conditions on reactor temperature,concentration distribution,and energy consumption were investigated.The research results showed that the heating coil could adopt different winding methods in the inlet and reaction sections.In the inlet section,the coil should be wound tightly to achieve rapid heating,while in the reaction section,the coil should be wound sparsely to avoid the appearance of"hot spots"in the reactor.The winding method of the coil was critical for optimizing the performance of the electromagnetic induction heating reactor by avoiding the"hot spots"and instability in the reactor and reducing its energy consumption.
