REGENERATION METHOD FOR DETERIORATED CATALYST

摘要

PROBLEM TO BE SOLVED: To provide a regeneration method for a deteriorated catalyst for regenerating a catalyst deteriorated due to lowered performance by an easy and low-cost process.

SOLUTION: In the regeneration method for a catalyst deteriorated due to lowered performance, an aqueous solution containing an active metal ion is absorbed into pores of the catalyst, and the water content in the absorbed aqueous solution is removed by vaporizing to deposit the active metal ion in the pores of the catalyst.
