Behavior of activated alumina in FCC catalysts were investigated by N _ 2 absorption, IR and XRD.───采用N2吸附法 、 IR和XRD等手段研究了活性氧化铝用于催化裂化(FCC)催化剂中的性能.

pollutants of tail gas, sewage, waste activated alumina, etc, in the hydrogen peroxide production by anthraquinone process are introduced. Their recovery treatment methods are put forward.───介绍蒽醌法双氧水生产中的尾气、污水、活性氧化铝等污染物，并提出回收处理方法。

process of removing fluorine with activated alumina is inappropriate to be termed as adsorption or ion exchanging, as lots of tests have shown.───大量的试验证明，活性氧化铝除氟不能简单归结为分子吸附或离子交换，要考虑具体的工艺过程。

The Industry - Standard Activated Alumina Desiccant Is Used Extensively In Compressed Air Dryers.───行业标准的活性氧化铝干燥剂广泛用于压缩空气干燥器.

At the same time, the effect of the concentration of sodium metaaluminate and regeneration time on the defluoridation capacity of activated alumina after being regenerated has been studied.

Methods outlined in the monograph include: use of crushed clay pots, bone charcoal, contact precipitation, or use of activated alumina (absorptive filter).

The Industry - Standard Activated Alumina Desiccant Is Used Extensively In Compressed Air Dryers.

Sodium metaaluminate as a regenerant has better regeneration effect on the activated alumina that is saturated and has adsorption capacity.
