Document Type and Number:
Japanese Patent JP6898627
Kind Code:
B2
Abstract:
The purpose of the present invention is to provide: a method for regenerating a carbonate-type layered double hydroxide, said method being capable of efficiently regenerating an anion-type Mg-Al layered double hydroxide (Mg-Al LDH), which has been used in an acidic exhaust gas treatment, to a carbonate-type Mg-Al LDH; and an acidic exhaust gas treatment facility. A method for regenerating a carbonate-type layered double hydroxide according to the present invention regenerates a carbonate-type Mg-Al LDH by bringing a mixed gas, which is at 70°C or higher and contains water and carbon dioxide at a concentration of 5 vol% or more, into contact with an anion-type Mg-Al LDH that is generated in an acidic exhaust gas treatment that uses the carbonate-type Mg-Al LDH.
