  • Publication number: 20160220943
    Abstract: In regenerating carbon dioxide capturing material, the amount of regeneration gas supplied to a carbon dioxide recovery column is reduced for higher energy efficiency and shortened regeneration time. A carbon dioxide recovery apparatus includes a carbon dioxide sorbing column, a heating unit, and first, second, and third channels. The carbon dioxide sorbing column contains a carbon dioxide capturing material. The heating unit heats the carbon dioxide capturing material. A carbon-dioxide-containing gas is introduced via the first channel into the carbon dioxide sorbing column. The regeneration gas is introduced via the second channel into the carbon dioxide sorbing column. A gaseous mixture containing a gas desorbed from the carbon dioxide capturing material is recovered via the third channel. The heating unit preheats the carbon dioxide capturing material, and then the regeneration gas is introduced into the carbon dioxide sorbing column to recover carbon dioxide from the carbon dioxide capturing material.

  • Publication number: 20160199808
    Abstract: Provided is a carbon dioxide capturing material that captures a large amount of carbon dioxide, less suffers from decrease in an amount of the captured carbon dioxide even after firing, and has excellent heat resistance. The carbon dioxide capturing material separates and recovers carbon dioxide from a carbon-dioxide-containing gas. The capturing material includes an oxide containing Ce and Al. The oxide contains Ce in a highest content among metal elements in the oxide and contains Al in a content of 0.01% by mole to 40% by mole.
