Activated Alumina Adsorbent For Gas Drying

Our activated alumina adsorbent is produced from high-purity aluminum hydroxide through controlled thermal activation.
This process creates a uniform pore structure with abundant micro- and mesopores, allowing rapid diffusion and strong physical adsorption of water molecules from gas streams.

Compared with ordinary drying media, Zibo Xiangrun activated alumina offers:

Higher adsorption efficiency under dynamic gas flow

Better resistance to mechanical abrasion

Stable structure under repeated regeneration cycles

It can be used as the main desiccant layer or as a protective pre-layer before molecular sieves to improve overall system reliability.

* High specific surface area: typically ≥300m²/g

* High crush strength, suitable for high-pressure gas systems

* Low dust and low attrition：typically <0.1 wt%

* Excellent thermal and chemical stability

* Long service life with stable regeneration performance

These advantages help ensure consistent outlet dew point and reduce overall operating costs.

Q1: What types of gases can activated alumina adsorbent be used to dry?

A1: Activated alumina is widely used for drying compressed air, natural gas, hydrogen, nitrogen, oxygen, instrument air, and various process gases in petrochemical and refinery plants.

Q2: Does activated alumina generate dust and damage downstream equipment?

A2: High-quality activated alumina, after proper calcination and sieving, has a low abrasion rate and extremely low dust generation. Using activated alumina with high compressive strength and a low dust grade helps protect downstream valves, compressors, and molecular sieve beds.

Q3: What is the service life of activated alumina in gas drying systems?

A3: Under normal operating conditions, activated alumina from Zibo Xiangrun Environmental Engineering Co., Ltd. typically lasts for about 5 years.

Q4: Can activated alumina be used with molecular sieves?

A4: Yes. In many systems, activated alumina is used as a pretreatment layer to remove large amounts of moisture, while molecular sieves are used in downstream processing to achieve ultra-low dew points.

Q5: Can activated alumina be customized for special gas drying systems?

A5: Yes. Particle size distribution, adsorption performance, and packaging can all be customized according to specific system requirements and project conditions.
