흡착 및 촉매 작용에 활성 알루미나 적용

활성 알루미나는 큰 비표면적, 다양한 기공 구조 및 기공 크기 분포 및 풍부한 표면 특성을 가지고 있습니다. 따라서 흡착제, 촉매 및 촉매 지지체에 광범위하게 사용됩니다.

Alumina for adsorbent and catalyst carrier is a fine chemical and also a special chemical. Different uses have different requirements on the physical structure, which is the reason for its strong speciality and many varieties and brands. According to statistics, the amount of alumina used as catalyst and carrier is more than the total amount of catalyst used in molecular sieve, silica gel, activated carbon, diatomaceous earth and silica-alumina. It can be seen that alumina plays a pivotal role in catalysts and supports. Among them, η-Al2O3 and γ-Al2O3 are the most important catalysts and supports. They are both spinel structures with defects. The difference between the two is: The regularity is different (γ>η) and the Al-O bond distance is different (η>, 차이는 0.05-0.1nm).
