High-Performance Catalyst for Dehydrogenation and Dealkylation of Hydrocarbons
CATADIENE™
Edition Date :
February 06, 2026
CATADIENE™ is a high-performance catalyst for selective dehydrogenation and dealkylation of hydrocarbons. Based on the Houdry process of catalytic cracking, CATADIENE technology and catalysts are used in butane-to-butadiene and isopentane-to-isoprene petrochemical processes.
The reliable, proven process operates at vacuum conditions and lower reactor temperatures to maximize conversion of n-butane to n-butylenes and butadiene while minimizing costs.
CATADIENE technology is exclusively licensed by our process partner, Lummus Technology, while the catalysts are solely produced and supplied by Clariant.
