A method for producing chlorine production for regenerated catalyst, how regeneration of deteriorated catalyst, manufacturing methods and activity maintenance method of catalyst for chlorine production of chlorine
PROBLEM TO BE SOLVED: To provide a method for obtaining a regenerated catalyst at a high yield by efficiently and economically regenerating a deteriorated catalyst, which has activity decreased with time, at a high recovery rate when producing chlorine by oxidizing hydrogen chloride with oxygen using a fluidized-bed reactor.;SOLUTION: The method for producing the regenerated catalyst for chlorine production includes, one or more times, a treatment step of impregnating a copper-containing solution into the deteriorated catalyst which has been used in chlorine production by oxidizing hydrogen chloride with oxygen using the fluidized-bed reactor. The deteriorated catalyst includes a carrier composed of porous particles on which active components are supported, where the active components include (A) a copper element, (B) an alkali metal element and (C) a lanthanoid element having a bond dissociation energy between the lanthanoid element and oxygen of 100-185 kcal/mol at 298 K.;COPYRIGHT: (C)2012,JPO&INPIT
