Experimental Analysis of Inductive Heating of Catalytic Beds

To reduce CO2 emissions in the chemical industry, already established endothermic reactors should be heated with electrical energy. One promising possibility is inductive heating, in which electrical energy can be transferred to the susceptor (material to be heated). The uniform heating of the susceptor material is necessary for stable operation in chemical reactors and is therefore investigated in this work. For this purpose, a non-reactive test setup was built that enables the investigation of inductive heating of different susceptor materials and measurement of the temperature distribution under defined non-reactive conditions. In the first tests, temperatures of up to 800 degrees C were reached and an uneven heat input in a bed of stainless-steel rings was observed. A non-reactive test section was set up to investigate the inductive heating of different materials. In this test section, the power uptake by the suszeptor can be analyzed and evaluated based on the measurement of the temperature distribution and controlled heat removal by the incoming gas. image
