Abstract
Official abstract text for this publication.
Enhanced concentration of carbon dioxide, typically of carbon dioxide in the air, is advantageous in areas such as agriculture and horticulture involving raising of plants which utilize carbon dioxide for photosynthesis. Various carbon dioxide concentration apparatus have been developed, but the problems thereof are numerous. It is accordingly the purpose of the present invention to develop an adsorbent having exceptional adsorption of carbon dioxide, and to provide an apparatus for concentration of carbon dioxide in the air through the use thereof. Provided is a pressure swing concentration apparatus that uses ferrierite as the adsorbent, the ferrierite having been subjected to alkali treatment to give a pore diameter of 0.01-1 μm and a pore volume of 0.1 mL/g or above.
First claim
Opening claim text (preview).
What we claimed: 1 . A carbon dioxide concentrating apparatus comprising a pressure swing type concentrating device using ferrierite as an adsorbent material, characterized in that said ferrierite is subjected to alkaline treatment to have pores in diameter of 0.01 through 1 μm and pore volume of 0.1 mL/g or more. 2 . A carbon dioxide concentrating apparatus as set forth in claim 1 wherein carbon dioxide in the atmosphere is concentrated 20 times or more. 3 . A method of supplying carbon dioxide which supplies, for growing plants, carbon dioxide concentrated by the apparatus as set forth in claim 1 .
