Carbon Dioxide Absorbing Material, Method for Producing Carbon Dioxide Absorbing Material, Method for Absorbing Carbon Dioxide, and Apparatus for Absorbing Carbon Dioxide

摘要

A carbon dioxide-absorbing material that can greatly improve an absorption amount of carbon dioxide up to near the theoretical value, a method for producing the carbon dioxide-absorbing material, a method of absorbing carbon dioxide using the carbon dioxide-absorbing material, and an apparatus for absorbing carbon dioxide are provided.;The carbon dioxide-absorbing-material of the present invention contains lithium titanate, the lithium titanate comprising 70 mol % or more of Li₄TiO₄ and 30 mol % or less of Li₂TiO₃. Furthermore, the carbon dioxide-absorbing material of the invention is obtained by the method for producing a carbon dioxide-absorbing material of the invention described below. That is, the absorbing material is obtained by the production method of the invention which produces the same by mixing given raw materials such that the atomic ratio between lithium and titanium is from 3.5 to 5.0, and subjecting the resulting mixture to heat treatment. The method for absorbing carbon dioxide of the invention includes a carbon dioxide absorption step. The apparatus for absorbing carbon dioxide of the invention is provided with carbon dioxide absorption means that absorbs carbon dioxide in the carbon dioxide-absorbing material of the invention.
