Ethylene Oxide Catalysts
Shell Catalysts & Technologies has been reinventing ethylene oxide catalyst possibilities for more than 80 years, constantly and consistently improving their performance. Shell was the inventor of every class of EO catalyst. The inventions of the first High Selectivity and later High-Performance catalysts define the current landscape of EO production globally.
The most important measure of ethylene oxide catalyst performance is selectivity, defined as the molar yield of ethylene oxide produced per molar quantity of ethylene reacted. Another important parameter is activity, the catalyst temperature required to achieve the desired EO production level. Shell Catalysts & Technologies’ scientists have focused on improving not only the initial selectivity performance of our ethylene oxide catalysts but also the activity and the average catalyst selectivity throughout life.
Our High Selectivity catalysts offer unrivalled initial selectivity and excellent stability, leading the industry in performance. Our Hybrid catalysts were created to offer an alternative to plants designed to run High Activity catalyst, and over time have improved to a level where they now offer a huge enhancement in selectivity over High Activity.
Highly active, highly selective EO catalysts make up Shell Catalysts & Technologies’ High-Performance catalyst family which can operate for long periods at significantly higher work rates than other catalyst types and are more tolerant of higher CO2 concentrations. Additionally, Shell’s High-Performance EO catalysts also experience consistently slower performance decline over time, thereby offering the highest average selectivity levels of any catalysts available.
