Experimental studies on electrothermal regeneration of carbonaceous adsorbent in inductively heated column

A new electrothermal cyclic desorption process at induction heating taking place in the adsorption column filled with mixture of Sorbonorit 3 activated carbon and granular iron particles loaded with n-butanol is considered. The various volumetric fractions of the iron particles (equivalent diameter: dpFe=1.7 mm) in adsorbent bed (ϕ=0.1 and ϕ=0.2) were used in experiments to intensify internal heat sources capacity. The cyclic adsorption-desorption steps were carried out at various inductor coil current intensities, nitrogen mass flux densities and inlet temperatures. Maximum adsorbent bed regulation temperature was imposed at level of Treg = 453.15 K to avoid activated carbon overheating. The analysis of experimental results enabled assessment of the process parameters range for which proposed modified adsorbent bed regeneration method is feasible and efficient.
