Rezel-PDH -- Dehydrogenation catalysts convert light paraffins into olefins
Back Next
Rezel chromium based PDH catalysts are used in the petrochemical industry to produce propylene, n-butylene and i-butylene from light paraffins using the dehydrogenation technologies, and also from butylene to butadiene. Rezel dehydrogenation technology and catalyst correspond to a reliable production process for on-purpose olefins/butadiene production. 
 
New generations of catalysts with significant performance improvement have been commercialized successfully in the last year. Rezel dehydrogenation catalyst offers superior selectivity and on-stream efficiency. Increasing production capacity for our proprietary, high-performance catalysts is an important part of customer’s growth strategy to capture opportunities driven by shale gas development which creates significant need for on-purpose olefin production. 
 
Rezel PDH catalyst reached over 45% in single pass conversion, over 84% in propylene yield for the propane dehydrogenation and the catalyst loss is below 4 Kg per metric tons of propylene product. For iso-butane dehydrogenation, the single pass conversion can even reach as high as 52% with the unbelievable product selectivity of 85% and under the same low level catalyst consumption.

Rezel-PDH catalyst are widely accepted by Chinese customer in fluid bed PDH unit.
