- the CO 2 separation and recovery system using the CO 2 capturing material introducing CO 2 containing gas to the capturing material container filled with CO 2 capturing material, capture and removal of CO 2 by contacting the CO 2 capturing material and gas To do. Then, the captured CO 2 is desorbed and recovered by heating the capture material or reducing the pressure in the capture material container. CO 2 capturing material the CO 2 desorbed, is used again CO 2 containing gas After cooling to capture and removal of the supplied CO 2.
- Patent Document 1 focuses on the average pore diameter and is an oxide containing Ce and an element selected from K, Mg, Al, and Pr for the purpose of efficiently capturing carbon dioxide,
- a carbon dioxide scavenger is described that contains elements selected from K, Mg, Al, and Pr in total and in a molar ratio of 0.01 to 1.00 in terms of metal with respect to Ce.
- the carbon dioxide capturing material described in Patent Document 1 has an initial specific surface area of 100 m 2 / g or more, but when calcined at 500 ° C., the specific surface area is about 80 m 2 / g. I understood. That is, this carbon dioxide capturing material has a large decrease in specific surface area due to firing, and there is room for improvement in terms of heat resistance. Generally, the larger the specific surface area, the greater the amount of carbon dioxide trapped.
- An object of the present invention is to provide a carbon dioxide scavenging material having a high heat resistance and a large amount of carbon dioxide scavenging, and a small decrease in the amount of carbon dioxide scavenging due to firing.
- the carbon dioxide capturing material of the present invention is for separating and recovering carbon dioxide from a carbon dioxide-containing gas, is an oxide containing Ce and Al, and has the highest content among the metal elements contained Is Ce, and the content of Al is 0.01 mol% or more and 40 mol% or less.
- CO 2 Al in capturing material is a graph showing Fe, Cu, a correlation between the content and the CO 2 capture of V and Mo.
- Fe of CO 2 in the capturing material is a graph showing the correlation between the amount of decrease in the content and CO 2 capture amount of Cu, V and Mo.
- the present invention relates to a carbon dioxide capturing material (hereinafter also referred to as “CO 2 capturing material”) for separating and recovering CO 2 from a CO 2 containing gas (carbon dioxide containing gas) such as combustion exhaust gas, and more particularly to capture CO 2 .
- CO 2 capturing material for separating and recovering CO 2 from a CO 2 containing gas (carbon dioxide containing gas) such as combustion exhaust gas, and more particularly to capture CO 2 .
- the carbon dioxide-containing gas is assumed to be combustion exhaust gas having a carbon dioxide concentration of 3 to 18% by volume, but is not limited to this, and exhaust gas from a chemical plant that handles solid reactions such as calcium carbonate. Can also be a target.
- the carbon dioxide concentration can be 18% by volume or more. Further, the higher the carbon dioxide concentration, the easier the recovery.
- the carbon dioxide concentration of the carbon dioxide-containing gas is not limited to 3% by volume or more, and even a gas having a lower carbon dioxide concentration can be a target.
- the CO 2 capturing material of the present invention is an oxide containing Ce and Al, the element having the largest content among the contained metal elements is Ce, and the Al content is 0.01 mol% or more and 40 mol. % Or less (0.01 to 40 mol%). It was confirmed that the CO 2 capturing material having this configuration can increase the CO 2 capturing amount.
- the reason why the effect can be obtained is that (1) Ce and Al form a complex oxide to form a site that easily captures CO 2 , and (2) the specific surface area of the capturing material increases. It is done. In the case where the Al content exceeds 40 mol%, or when only the Al oxide is used, the CO 2 trapping amount is reduced as compared with the case where only the Ce oxide is used. Even in the case where the Al content is 40 mol%, in order for the element having the highest content among the metal elements to be Ce, it is sufficient that Ce is contained at least 40 mol% or more. Here, there may be two types of “elements with the highest content”.
- mol% which is a unit of the content of the metal element, indicates a ratio when the total amount of the metal element contained in the CO 2 capturing material is 100 mol%. That is, the ratio obtained by using the contents of all metal elements contained in the CO 2 trapping material as the denominator and the contents of each metal element as the numerator is expressed on a molar basis.
- the more desirable Al content is 0.01 mol% or more and 30 mol% or less (0.01 to 30 mol%), and the particularly desirable Al content is 5 mol% or more and 20 mol% or less (5 to 20 mol%). is there.
- the CO 2 capturing material may be an oxide containing 0.01 mol% or more of at least one metal element of Fe, Cu, V and Mo in addition to Ce and Al.
- the CO 2 capture amount if the content is increased in these metal elements decreases, but the increase in CO 2 capture amount of Al contained, it can increase the CO 2 capturing amount as compared with the case of Ce oxide only.
- the Fe content is 10 mol% or less
- the Cu content is 7 mol% or less
- the V content is 3 mol% or less
- the Mo content is 3 mol% or less.
- the composition satisfies the following formula (1) obtained by weighting from the correlation between the content ratio of each element and the reduction amount of the CO 2 capture amount.
- the advantage by using the CO 2 capturing material of the present invention is that a raw material with low purity can be used, and a purification process for removing impurities can be reduced. As a result, raw material and equipment costs can be reduced.
- Compounds used as raw materials for synthesizing the CO 2 capturing material of the present invention include oxides, nitrates, chlorides, sulfates, carbonates, phosphates, hydroxides, oxalates, acetates, formic acid Examples include salt.
- the raw material of Ce may be a mineral such as monazite or bastonesite.
- Minerals may include lanthanides other than Ce (La, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu).
- Oxides containing Ce and these lanthanide elements increase the amount of CO 2 trapped compared to Ce-only oxides, so it is necessary to refine them to reduce the content of lanthanide elements other than Ce. There is no.
- a desirable content of these lanthanides is 0.01 mol% or more and 50 mol% or less in total, and more preferably 0.01 mol% or more and 30 mol% or less. When such a raw material is used, the purification cost can be reduced and the amount of captured CO 2 can be increased.
- Examples of the method for synthesizing the CO 2 capturing material of the present invention include chemical preparation methods such as impregnation method, kneading method, coprecipitation method and sol-gel method, and physical preparation methods such as vapor deposition method.
- chemical preparation methods such as impregnation method, kneading method, coprecipitation method and sol-gel method
- physical preparation methods such as vapor deposition method.
- a basic compound such as aqueous ammonia, sodium hydroxide (NaOH), calcium hydroxide (Ca (OH) 2 )
- Ce and Al may be coprecipitated.
- aluminum hydroxide (Al (OH) 3 ) forms aggregates (floc), thereby increasing the sedimentation rate of the synthesized product and shortening the time required for synthesis.
- the specific surface area is 130 m 2 / g even after firing at 600 ° C. Therefore, it is considered that the decrease in the carbon dioxide capture amount is small.
- the above firing temperature is higher than the actual regeneration temperature, it is high as an accelerated test for early determination as to whether or not the carbon dioxide capture material deteriorates during repeated adsorption and regeneration of the carbon dioxide capture material.
- a firing test at a temperature was performed. Actually, even when the use temperature is about 200 ° C., the deterioration gradually proceeds with long-term use.
- Firing at 600 ° C. is much more severe than firing at 500 ° C.
- the specific surface area after firing at 600 ° C. is larger than the specific surface area after firing at 500 ° C. It shows that it is excellent. This also indicates that it is strong against repeated use over a long period of time.
- the carbon dioxide capturing material of the present invention has higher heat resistance than the carbon dioxide capturing material described in Patent Document 1. This effect is considered to be due to the oxide containing Al in addition to Ce.

- a high specific surface area material in a mixed form may be used, and the minimum unit of the structure may be a granular, granular aggregate, or composite.
- the carbon dioxide capturing material is formed as a member, it is preferable to have a shape having air permeability so as to reduce pressure loss, for example, a porous body having a high porosity or a honeycomb shape may be used. It is good.
- the outer shape of the carbon dioxide capturing material may be bulk, plate-like, or the like. It should be noted at this time that the porosity should be reduced when increasing the purity of CO 2 in the recovered gas. That is, in the case of granularity and a small porosity, there is a disadvantage that the pressure loss increases, but the amount of gas other than CO 2 remaining in the voids decreases, so that the purity of CO 2 in the recovered gas can be increased. There are advantages.
- the recovery method by temperature swing recovery process by pressure swing, and recovery methods are exemplified by the pressure and temperature swing. These recovery methods may be determined in consideration of the pressure of the CO 2 -containing gas, the CO 2 partial pressure, and the temperature.

Description
上記課題の解決策としては、化学吸収法、物理吸収法、膜分離法、吸着分離法、深冷分離法などがある。その中に、固体のCO2捕捉材を用いたCO2分離回収法が挙げられる。
ここで、式中の単位はmol%である。
CO2捕捉材の周辺雰囲気のCO2分圧を減圧する方法は、上記に加えCO2以外のガスを流す方法が挙げられる。この際に使用するガスとしては、CO2と容易に分離できるガスが好ましく、特に冷却により容易に凝縮するという観点から水蒸気を使用する方法が挙げられる。
精製水1080gに硝酸セリウム六水和物26.05gを室温で激しく撹拌しながら溶解した。この水溶液を撹拌しながら28重量%のアンモニア水溶液を滴下してpHを9.0とした。8時間撹拌した後、1時間静置し、沈殿物を洗浄ろ過により収集した。その後、沈殿物を乾燥炉にて120℃で乾燥し、大気雰囲気下の電気炉にて400℃で1時間焼成し、得られたセリウム酸化物をCO2捕捉材とした。
比較例1に記載の合成法において、硝酸セリウム六水和物26.05gの代わりに、硝酸セリウム六水和物13.03gと硝酸アルミニウム九水和物11.25gとを用いたこと以外は同様の方法で合成した酸化物をCO2捕捉材とした。
ベーマイト(Condea製、Pural-SB1)5gを電気炉において大気下400℃で1時間焼成して調製したアルミニウム酸化物をCO2捕捉材とした。
比較例1に記載の合成法において、硝酸セリウム六水和物26.05gの代わりに、硝酸セリウム六水和物23.45gと硝酸鉄(III)九水和物2.42gとを用いたこと以外は同様の方法で合成した酸化物をCO2捕捉材とした。
比較例1に記載の合成法において、硝酸セリウム六水和物26.05gの代わりに、硝酸セリウム六水和物23.45gと硝酸銅(II)三水和物1.45gとを用いたこと以外は同様の方法で合成した酸化物をCO2捕捉材とした。
比較例1に記載の合成法において、硝酸セリウム六水和物26.05gの代わりに、硝酸セリウム六水和物23.45gとバナジン酸アンモニウム0.70gとを用いたこと以外は同様の方法で合成した酸化物をCO2捕捉材とした。
比較例1に記載の合成法において、硝酸セリウム六水和物26.05gの代わりに、硝酸セリウム六水和物23.45gとモリブデン酸アンモニウム1.06gとを用いたこと以外は同様の方法で合成した酸化物をCO2捕捉材とした。
CO2捕捉材は、直径40mmの金型を使用して、プレス機により200kgfでペレット化し、これを破砕した後、篩を用いて0.5~1.0mmの粒状に整粒した。その後、メスシリンダーを用いて1.0mlを測り、石英ガラス製反応管中に固定した。
-(各比較例のCO2捕捉量) …(2)
本図においては、Alを10%含有した場合(実施例1)を基準として表すため、比較例1に対する実施例1の増加量を破線で示している。すなわち、実施例1のCO2捕捉量は、比較例1に対して90mmol/L増加する。
