Internal heat source capacity at inductive heating in desorption step of ETSA process

A new electrothermal desorption process in which the heat for desorption is generated inside modified adsorbent bed by electromagnetic induction is considered. The novel numerical model of volumetric internal heat source capacity in bed composed of Sorbonorit 3 activated carbon and granular iron mixture, loaded with butan-1-ol is developed on experimental basis. The quantitative relationship between an electrical conductivity γAC(q,T) of the Sorbonorit 3 activated carbon and average butan-1-ol concentration in solid phase q, and average bed temperature T is determined. The relationship between an electrical conductivity γFe(T) of the granular iron and temperature T is also derived. The capacity of the volumetric internal heat source in bed of Sorbonorit 3 activated carbon and iron granular mixture bed depends primarily on: volume fraction of granular iron, current intensity of the inductor coil and temperature.
