Abstract
Official abstract text for this publication.
The present invention relates to a carbon dioxide absorbent used for absorbing carbon dioxide, a carbon dioxide absorbent composition used for producing the carbon dioxide absorbent, and a solid raw material for a carbon dioxide absorbent included in the carbon dioxide absorbent.
First claim
Opening claim text (preview).
The invention claimed is: 1. A solid raw material for a carbon dioxide absorbent, comprising: an active component; a first support; a second support; an inorganic binder; and a regeneration enhancer, wherein the second support comprises one or more selected from the group consisting of lanthanum aluminate, lanthanum carbonate, lanthanum acetate, lithium borate, sodium borate, and zinc borate, and wherein the second support has a specific surface area of 10 m 2 /g or more. 2. The solid raw material of claim 1 , wherein the active component comprises one or more selected from the group consisting of alkali metal oxides, alkaline earth metal oxides, alkali metal carbonates, alkaline earth metal carbonates, alkali metal bicarbonates, alkaline earth metal bicarbonates, and precursors thereof. 3. The solid raw material of claim 1 , wherein the first support comprises one or more selected from the group consisting of alumina, calcium silicate, magnesia, silica, hydrotalcite, ceria, lanthania, yttria, and tin oxide. 4. The solid raw material of claim 1 , wherein the inorganic binder comprises one or more selected from the group consisting of cements, clays, and ceramics. 5. The solid raw material of claim 1 , wherein the regeneration enhancer comprises one or more selected from the group consisting of titania and zirconia. 6. The solid raw material of claim 1 , wherein the solid raw material comprises: 5 to 70 parts by weight of the active component; 1 to 70 parts by weight of the first support; 1 to 60 parts by weight of the second support; 5 to 70 parts by weight of the inorganic binder; and 1 to 60 parts by weight of the regeneration enhancer. 7. The solid raw material of claim 1 , wherein the second support is a spherical particle having a size of 5 μm or less. 8. A solid raw material for a carbon dioxide absorbent, comprising: an active component; a first support; a second support; an inorganic binder; and a regeneration enhancer, wherein the second support comprises one or more selected from the group consisting of lanthanum aluminate, lanthanum carbonate, lanthanum acetate, lithium borate, sodium borate, and zinc borate, wherein the second support is a spherical particle having a size of 5 μm or less.
