FAQ

Q: What impurities does activated alumina remove in olefin purification?

A: It mainly adsorbs water, acid gases (e.g., CO₂, H₂S), and other trace polar contaminants that can deactivate catalysts.

Q: Why is olefin purification important?

A: Purifying olefin feeds improves downstream catalyst life and process efficiency, and prevents fouling and side reactions.

Q: Can the activated alumina be regenerated?

A: Yes, many activated alumina grades can be regenerated by controlled heating to desorb adsorbed impurities.

Q: How long does the material last?

A: Service life depends on feed impurity levels and operating conditions, but high mechanical strength and capacity help extend life.

Q: Is this product suitable for all olefins?

A: It is suitable for a wide range of olefin streams including ethylene, propylene and higher olefins, but selection should consider specific impurity profiles.

Q: How should it be stored?

A: Store in a dry, sealed environment to avoid presaturation by moisture and maintain performance.
