<p><P>PROBLEM TO BE SOLVED: To provide a method and an apparatus for regenerating a catalyst that use compact equipment and achieve easy control. <P>SOLUTION: A catalyst for producing an aromatic is regenerated by the method for regenerating a catalyst. The method includes a waste catalyst introducing step to introduce a waste catalyst C into a low temperature zone 23 of a single-stage type catalyst regenerating vessel 21 of which the bottom side is divided into a low temperature zone 23 and a high temperature zone 24 by a partition wall 22, a first burning step to supply an oxygen-containing gas to the low temperature zone 23 and to burn hydrogen in cokes of the waste catalyst C, an overflow step in which the waste catalyst C overflows from the low temperature zone 23 to the high temperature zone 24 after the first burning step, a second burning step to supply an oxygen-containing gas to the high temperature zone 24 and to burn carbon in cokes of the waste catalyst C to form carbon dioxide, and a regenerated catalyst discharging step to discharge the catalyst regenerated in the second burning step from the high temperature zone 24. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
