<p><P>PROBLEM TO BE SOLVED: To provide a method for regenerating an adsorbent which can prevent remaining of sulfur on the adsorbent and sulfur leakage to raw materials. <P>SOLUTION: The method for regenerating an adsorbent which regenerates an adsorbent for adsorbing sulfur in the raw materials includes a first heating process for heating a regeneration gas and the adsorbent while bringing them into contact with each other to desorb the sulfur from the adsorbent without deteriorating the sulfur, and a second heating process for heating the regeneration gas and the adsorbent after the first heating process while bringing them into contact with each other at a temperature higher than that of the first heating process. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
