Activated Alumina PSA Adsorbent
Activated alumina PSA adsorbent is a media adsorbent material with high porosity and dispersity. It has not only good adsorption performance, but also good pressure resistance, wear resistance and heat resistance. It has a long service life and can reduce the production cost of enterprises with the large surface area and pore volume.
Product Introduction
Brief Introduction
Activated alumina PSA adsorbent balls produced by Avant has uniform particle size, large surface area, high mechanical strength and high moisture absorption.
This product of ours is a specially adsorbent for PSA gas separation device. PSA technology has been widely used in petroleum, chemical industry, metallurgy, environmental protection, food, electronics, aviation and other industries.
Activated alumina desiccant is not only produced for drying, but also can absorb the vapor of lubricating oil from contaminated oxygen, hydrogen, carbon dioxide, natural gas, etc.
At present, activated alumina PSA adsorbents has played an important role as a desiccant and purifier in the electronics industry, air drying of automatic instruments, fertilizer, steel, and petrochemical industries.

Pressure swing adsorption(PSA) recycle is the recycle of adsorption and regeneration. The adsorption process is that the adsorbent absorbs some components of the mixture when pressurized, and the unabsorbed components flow out through the adsorbent laminar flow. When the adsorbent is saturated with strongly adsorbed components, the adsorption tower needs to enter the regeneration process, namely desorption process.
The products produced by us can give full play to their adsorbability and good reproducibility in the adsorption process, and can be reused for many times. The effective stability and high adsorbability of the device are guaranteed, and the operating efficiency is greatly mentioned.

Our activated alumina PSA adsorbent material is selling well in the Middle East, India, Central Asia and Southeast Asia.
Regeneration life up to 5 years. Because of it's excellent adsorption capacity and recycling, it greatly saves cost and wasted time for the operation of PSA units in industrial production.
