Product Introduction
In air separation (ESR) equipment, the pretreatment of raw air is a crucial first step determining the safety, efficiency, and stability of the entire system. Untreated compressed air contains large amounts of water vapor, carbon dioxide, and hydrocarbons; these impurities can freeze at low temperatures, clogging pipes and equipment. Activated alumina, as a pre-desiccant in the air separation purification system, plays a vital role. Through its superior physical properties, it efficiently removes the vast majority of moisture, providing robust protection for the subsequent molecular sieve purification layer, ensuring the long-term, low-cost operation of the air separation unit.
Activated alumina for air separation equipment has numerous micropores and a large surface area, making it suitable for use as an absorbent desiccant and catalyst carrier. It is a desiccant for trace amounts of water and an adsorbent for polar molecules. Due to the polarization properties of the adsorbed molecules, it exhibits strong adsorption for water, oxides, acetic acid, and alkalis.
Product Function
1. Deep Adsorption and Drying, Removing Moisture
Its large specific surface area and microporous structure allow it to lock in moisture through physical adsorption, achieving deep air drying.
2. Synergistic Removal of Carbon Dioxide
Activated alumina can also assist in adsorbing some CO₂, improving overall purification efficiency.
3. Strong Hardness Protects Core Equipment, Ensuring System Stability

FAQ
Q1: What is the typical service life of activated alumina?
A: Under normal operating conditions, the service life of Zibo Xiangrun's activated alumina is generally 2-4 years. The specific service life depends on the temperature and humidity of the inlet air, the volume of gas processed, and the equipment's operating cycle.
Q2: How is degraded activated alumina regenerated?
A: Regeneration is usually achieved through backflushing with heated waste nitrogen (or other inert gases). We can provide standard operating instructions.
Q3: Can activated alumina and molecular sieves be mixed and packed?
A: No, they must be packed in strict layers.
Q4: Do you have molecular sieves suitable for air separation equipment?
A: Yes, please contact us.
