Activated Alumina
Introduction:
Activated alumina has a large surface area, many micro-pores, well disperser high strength and thermal stability, which is widely used as an absorber, desiccant and catalyst carrier in chemical, petrochemical and fertilizer industry. It can also widely used in the deep drying of cracked gas, ethylene and propylene, hydrogen-generation, air separation, instrument air drying and fluorine treatment for H2O2, also in the absorbing pollution material, such as H2S, SO2, HF and paraffin in the water gas. So it has a high affinity for water/impurity and active catalyst. According to the applications of balls, there are 3 types of Activated Alumina Sorbent, Activated Alumina Desiccant and Activated Alumina Catalyst carrier. Meantime interior composition of the crystal phase was divided into mode Y and X-P.
Application:
The activated balls are widely utilized in the drying agent of multiform gas and liquid, also function is used as absorbent, desiccant, catalyst support in reactors for petrochemical industry, chemical industry, and fertilizer industry and so on.
