Acetylene Hydrogenation Catalysts 

E-Series® catalysts are used in hydrogenating acetylene to ethylene in front-end deethanizer and depropanizer plant configurations. Front-end acetylene conversion involves the hydrogenation of acetylene prior to the removal of methane and lighter components from the cracked gas system. To achieve optimum performance, E-Series® catalysts are custom-formulated to meet the requirements of diversified ethylene plants.

E-Series® catalysts offer:
  • Excellent selectivity
E-Series catalysts quantitatively remove ethylene while limiting the amount of over-hydrogenation of ethylene to ethane.
  • Stable ARU operations
 E-Series catalysts are much more stable when operating at the higher conversions necessary to lower the acetylene to tighter ethylene specifications.
  • Resistance to CO changes
Reactors operated with E-Series catalysts are highly resistant to temperature excursions due to fluctuations in carbon monoxide content in the feed.
  • Ease of reactor startup
Using E-Series catalysts enables a quicker startup while minimizing off-spec production compared to traditional catalysts.
  • Ease of use
E-Series catalysts can easily be regenerated by either ex- or in-situ methods. The high crush strength of these catalysts enables them to maintain their integrity through multiple handlings.
