(Example 2) Coal ash having a mixing ratio of 80:20 and cement were mixed with an appropriate amount of water, granulated with a pelletizer, and 2
By leaving it for 4 hours, an adsorbent having a particle size of 2.5 to 0.3 mm was obtained. This adsorbent was housed in a glass container having a capacity of 1000 cc, and carbon dioxide gas was filled therein, and the lid was closed.

(Embodiment 3) The adsorbent in which the carbon dioxide gas is adsorbed in the embodiment 2 is housed in a hermetically sealed container, and this container is connected to another hermetically sealed container having a vacuum inside to separate the carbon dioxide gas adsorbed by the adsorbent. I tried to try. However, carbon dioxide was not detected in any of the sealed containers, confirming that the carbon dioxide was completely immobilized on the adsorbent.

た。Further, the adsorbent having adsorbed carbon dioxide was immersed in distilled water and the pH was measured to be about 8. The adsorbent before adsorption was also immersed in distilled water in the same manner, and the pH was measured to be about 12. This also indicates that Ca (OH) 2 having alkalinity reacts with CO 2 to generate CaCO 3 and neutralize it, that is, carbon dioxide gas is immobilized. (Example 4) Coal ash having a mixing ratio of 8: 2 and an appropriate amount of water were added to cement and mixed, granulated by a pelletizer, and allowed to stand for 24 hours to obtain an adsorbent having a particle diameter of 2.5 to 0.3 mm. Got 30 g of this adsorbent was placed in a glass container having a capacity of 1500 cc, and carbon dioxide gas was filled therein, and the lid was closed.

It was calculated as r. (Example 5) The same test as in Example 4 was carried out by changing the mixing ratio of coal ash and cement to 7: 3 and 6: 4, and the mixing ratio of 7: 3 was about 2.5 minutes later, With a mixing ratio of 6: 4, the polyethylene container began to deflate after about 4 minutes.

に収容し、その中に炭酸ガスを満たして蓋を閉めた。Comparison of the results of Examples 4 and 5 shows that the carbon dioxide adsorption performance of the adsorbent having a mixture ratio of coal ash and cement of 8: 2 is excellent. (Example 6) Water was added to and mixed with a mixture of coal ash and cement having a mixing ratio of 8: 2, and granulated by a pelletizer.
By standing for 4 hours, four kinds of adsorbents having different particle diameters were obtained. This adsorbent was placed in a polyethylene container having a capacity of 500 cc, and carbon dioxide gas was filled therein, and the lid was closed.

After a lapse of time or more, carbon dioxide gas was filled again and the lid was closed. The same procedure was repeated 10 times, and the time when the polyethylene container started to deflate was measured each time. Further, the adsorbent for the 10th time was immersed in distilled water to measure the pH. The results are shown in Table 1 below.

果を下記表２に示す。From Table 1 above, it can be seen that the adsorption speed of the adsorbent having a smaller particle size is faster. In particular, the particle size is 0.
It can be seen that in the case of 3 to 0.6 mm, the adsorption speed was extremely reduced after the 9th time and the adsorption amount was saturated up to the 8th time. The pH is neutral. (Example 7) By the same procedure as in Example 6, 7 kinds of adsorbents were produced by changing various raw materials, and in the same manner as in Example 6, the time for the polyethylene container to start deflating was measured. The results are shown in Table 2 below.

吸着スピ−ドはそれほど変わらないことがわかる。From Table 2 above, it can be seen that the adsorbent having a large amount of cement has a slower adsorption speed of carbon dioxide gas although the content of CaO is larger. It is considered that this is because the structure of the granulated sand became dense due to the large amount of cement. That is, in order to accelerate the adsorption speed, it is preferable that the adsorbent particles are porous. It should be noted that for the cement content of 20%, the adsorption speed does not change so much even if the other raw materials change.
