Olefin polymerization is the foundation of modern plastics—and catalyst performance decides precision, throughput and how much of the feed becomes on-specification polymer. Evonik supplies purification adsorbents that protect polymerization catalyst systems from feed contaminants. DYNOCEL® adsorbents remove water, alcohols, ammonia, ethers, ketones, mercaptans, hydrogen sulfide, carbon dioxide and carbonyl sulfide from ethylene, propylene, isobutylene and 1-octene process streams. Removing these polar and acid-gas contaminants upstream protects the polymerization catalyst from poisoning. Compared with running the same unit on unpurified feed, this supports consistent polymer quality and fewer off-specification batches.
Why Choose Evonik for Olefin Polymerization?
Proven Performance: Trusted catalyst technologies for consistent, high-quality polymer production.
Regenerable Purification: selected DYNOCEL® grades can be regenerated and returned to service for further cycles instead of being discarded after one use. Compared with a single-use adsorbent in the same duty, this means less fresh adsorbent purchased and less spent material for disposal across the life of the unit.
Tailored Expertise: Our specialists partner with you to design solutions that meet your unique process requirements.

Your Evonik Advantage
Purification adsorbents matched to your monomer and comonomer streams, with regenerable grades where the duty allows. Compared with unpurified feed, the aim is stable catalyst performance and fewer off-specification batches; compared with a single-use adsorbent, less spent material per operating year. Our engineers work with you to define the achievable result for your unit.
