Clariant, Linde unveil groundbreaking ethylene catalysts



Clariant Catalysts has teamed up with Linde Engineering to develop new catalysts for the oxidative dehydrogenation of ethane (ODH-E), an innovative, low-emissions catalytic technology to produce ethylene. The novel catalyst is a step change in selectivity and productivity, now making ethylene production via ODH-E commercially feasible.

Clariant’s ODH catalysts are available exclusively for Linde Engineering’s innovative EDHOX catalytic on-purpose ethylene technology. In contrast to conventional steam cracking, which operates at process temperatures up to 900°C, EDHOX operates at moderate temperatures—below 400°C, enabling comparatively low CO₂ emissions. Also inherent to Linde Engineering’s process are the sequestration of CO₂ and the potential for electrification. Together, these differences lead to a reduction of CO₂ emissions by up to 100% compared with conventional steam cracking.

The new catalysts by Clariant are the first to offer high selectivity to ethylene and acetic acid (up to 93%) for the oxidative dehydrogenation of ethane, while also demonstrating outstanding productivity at such conditions, minimizing the formation of by-products. Furthermore, the development of the new catalysts and their impact on CO₂ emissions support Clariant’s objectives to drive low-carbon solutions through sustainable innovation and to generate value with safe chemistry and the responsible use of resources.
