The invention discloses a table separating method of catalysts with different inactivation degrees. The table separating method comprises the following steps of: 1, removing oil on the catalysts to ensure that the catalyst is in a free-flowing state; 2, separating catalysts with different inactivation degrees by using a table separating method, wetting the catalyst subjected to oil removal by using water containing a surfactant, sending the wetted catalyst to a feeding tank on the upper corner on the table surface of a separating table, wherein the catalysts are separated on the table surface with a reciprocating strip or groove. Compared with the prior art, the preparation method provided by the invention has a simple process, is easy to operate, has good separation effect, and can be used for effectively separating fluidized bed hydrogenation catalysts with different inactivation degrees.
