活性アルミナ

アルミナを触媒として使用する一般的な形態は、「活性アルミナ」と呼ばれます。これは、大きな表面積を持つ多孔質で高度に分散した固体材料です。その微多孔質表面は、吸着性能、表面活性、優れた熱安定性など、触媒に必要な特性を持っています。そのため、化学反応において触媒および触媒担体として広く使用されています。...

Chemical方法:ゾルゲル法などの方法を使用化学的方法によって調製された活性アルミナは、より完全な細孔構造とより均一な細孔体格分布の利点があります。


2.活性アルミニウムの特性Oxide

The活性アルミナは比表面積と多孔性が高く、表面に多数の酸素空孔があり、強力な吸着および触媒特性を持っています。

Meanwhileに、活性アルミナは優れた高温耐性と化学的安定性を持ち、水、酸、アルカリおよびその他の化学物質によって容易に侵食されません。

Therefore、活性アルミナは吸着、触媒、分離などの分野で幅広い応用の見通しを持っています。
