Zinc Oxide Adsorbent

AMBIENT-TEMPERATURE SULFIDE-REMOVAL ADSORBENT HTZM
1.Product features and scope of application
zinc oxide adsorbent HTZM-1 is applicable to deep desulfurization of liquid propylene and industrial feed gases at ambient temperature. It not only absorbs hydrogen sulfide, but also has certain conversion and absorption capability for COS in the stream.Overall sulfuri H2S+COSi in the treated stream can be less than 0.1ppm.

No regeneration is needed for spent adsorbent. But absorption may continue after the adsorbent bed is broken through , until the catalyst is finally saturated with sulfur. For example, feed stream can pass through 1st reactor even when it has been broken through, until it is saturated with sulfur and changed. This lowers sulfur content in the stream to 2nd reactor and makes full play of the absorption capacity of the adsorbent in 1st reactor.
