Microwave heating in heterogeneous catalysis: Modelling and design of rectangular traveling-wave microwave reactor

Microwave irradiation can intensify catalytic chemistry by selective and controlled microwave-catalytic packed-bed interaction. However, turning it to reality from laboratory practical applications is hindered challenges in the reactor design scale-up. Here, we present a novel, rectangular traveling-wave microwave (RTMR) provide an easy-to-handle, 3-step procedure of such reactor. The multiphysics model couples electromagnetic field, heat transfer, fluid dynamics order optimize geometrical parameters operational conditions for microwave-assisted heterogeneous catalysis. results show that energy input/output ports should be well-positioned matched; otherwise, would significantly decrease efficiency. In terms transmission, RTMR presents mix between standing wave systems. Gas space velocity input temperature affect profile, gas–solid no significant difference under certain contact.
