Description

Chemical Catalyst TiO2 Catalyst Support in Heterogeneous Catalysis

Activated Alumina, there are many micro-paths, so the specific surface is large. Zhongci Activated Alumina, the defluorinate effect is good. The capacity is stable. It has high strength, low abrasion, no soften in water, no expansion, no powdery no crack. It can widely used in the deep drying of cracked gas, ethylene, hydrogen-generation, air separation, instrument air drying and fluorin treatment for water, also in the absorbing pollution material, such as H2S, SO2, HF and paraffin in the waste gas, especially in the drinking water defluorinate.

Activated Alumina is an excellent desiccant for drying a wide variety of liquids and gases. It's high attrition resistance and crush strength. It has larger water adsorption capacity comparing to molecular sieve at high relative humidity and providing long service life with performance at or below dew point specifications. Activated alumina is widely used in large and small dryers. It is appropriate for use in dehydrating gases in both thermally regenerative and pressure swing adsorption (PSA) process.

Typical Chemical Formula: Al₂O₃·nH₂O (0≤n≤0.8).
