n modern air separation units (ASUs), maintaining gas purity is critical to both process efficiency and safety. Even trace amounts of carbon monoxide (CO) can compromise downstream operations, affect product gas quality, and pose safety risks in systems handling oxygen and nitrogen. To address this challenge, DEAI CHEM’s Hopcalite Catalyst 4×8 mesh provides an effective and durable solution for CO removal.
Product Overview
Hopcalite Catalyst 4×8 mesh is a granular catalyst formulated from manganese dioxide (MnO₂) and copper oxide (CuO). This composition allows it to convert carbon monoxide (CO) into carbon dioxide (CO₂) efficiently under ambient temperature and dry air conditions, without requiring external energy input. Its high surface area and mechanical strength ensure consistent performance over long operating periods, even in high-flow industrial environments.
The catalyst appears black to dark brown and is optimized for use in fixed-bed filtration or purification systems. Its 4×8 mesh size provides a balance between low pressure drop and high catalytic activity, making it particularly suitable for applications involving large air volumes, such as those found in air separation and cryogenic gas purification systems.
Application in Air Separation Units
In air separation plants, where gases such as oxygen, nitrogen, and argon are extracted through cryogenic distillation, the purity of feed air directly determines final product quality. Trace CO in the air stream can lead to contamination of high-purity gases and even interfere with downstream catalysts or adsorption systems.
By installing Hopcalite Catalyst 4×8 mesh in the purification section, CO is continuously oxidized to CO₂ before entering the cold box or cryogenic distillation column. This ensures that the separated gases meet strict purity standards, protecting both system performance and end-user safety.
Key advantages in ASU applications include:
Stable operation at ambient temperatures — no additional heating required.
Continuous CO conversion efficiency — maintains gas purity throughout system operation.
Extended service life — excellent durability under dry, oxygen-rich conditions.
Low maintenance requirements — reduced system downtime and operational costs.
Broader Use Across Industries
Beyond air separation units, Hopcalite Catalyst 4×8 mesh is widely used in compressed breathing air purification, escape mask systems, and cryogenic gas purification units. Its reliability and efficiency have made it a trusted choice in safety-critical environments where clean air is essential.
