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

摘要

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: d(pFe), = 1.7 mm) in adsorbent bed (phi = 0.1 and phi = 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 T-reg = 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. (C) 2016 Elsevier B.V.
