| Outline of Final Research Achievements |
Mesoporous processing was performed on Mo adsorbent alumina. The firing temperature was gradually changed to 500 - 1200 degrees and mesoporous structure with many pores on the surface was confirmed with a scanning microscope. The specific surface area is 275 m 2 / g when baked at 600 ° C., the specific surface area is 230 m 2 / g at 700 ° C. and Mo adsorption amount was as high as 40 mg / g, which was about 3 times higher than that of the existing alumina which specific surface area is 110 m 2 / g and Mo adsorption amount is 10 - 20 mg / g,. On the other hand, at 900 ° C, the specific surface area was 139 m 2 / g, which is equivalent to that of existing alumina, and it became clear that the surface area and Mo adsorption ability greatly changed by changing the conditions such as firing temperature.
