Activated Alumina
Activated Alumina
For the reason of activated alumina’s large capacity of absorption, large surface area, high strength and thermal stability, it has been widely used as an absorber, desiccant and catalyst carrier in chemical, petrochemical and fertilizer industry.
It can also be 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. We are a leading manufacturer of high-quality activated alumina products, which are specially designed to meet the diverse needs of various industries.
