Hydrogen recovery from metal particle dispersed salt by selective microwave heating

Abstract We discussed with experiments the selective heating behavior of a mixture of molten salt and metal powder containing hydrogen in a single-mode cavity by 2.45 GHz microwave. The experimental device consists of two single-mode devices that intersected perpendicularly. In the common cavity at the two crossing single-mode devices, one microwave generates the maximum electric field of standing wave, and another microwave generates the maximum magnetic field of microwave. Thus, the sample located at the crossing can be selectively heated by the inputting electric field and/or the magnetic field. The frozen salt can be heated and melted by the electric field. Hydrogen was recovered from the metal powder in the molten salt by magnetic heating.
