New method of electro-thermal regeneration on activated carbon fiber

For reducing using cost of activated carbon fiber(ACF) and promoting its application,a new regenerating method was developed.With formaldehyde as media,dynamic adsorption and electro-thermal desorption were used to investigate the electro-thermal regeneration behavior of ACF with emphasis on factors influencing electro-thermal regeneration of ACF.The experiment results revealed that the saturation value of adsorption of formaldehyde on ACF wad was(299.5 mg/g,) the time of electro-thermal regeneration was(5 min,)the efficiency of electro-thermal regeneration was(91.3%,) and the loss of ACF was small.It was proved that electro-thermal regeneration of ACF was a relatively ideal method characterized by short regeneration time,high regeneration efficiency,little loss of adsorbent and easy operation.
