Clariant introduces hydrogenation catalyst with high ethylene selectivity
announced the launch of OleMax 260, a new selective hydrogenation catalyst with extremely high ethylene selectivity and operational stability. Specially developed for ethylene producers with “frontend” process configurations, OleMax 260 offers a new solution to increase yields and profits while ensuring safer and more sustainable operation.
OleMax 260 provides a near perfect selectivity to ethylene (close to 100%), resulting in significant economic benefit for the operator. Perhaps more important is the catalyst’s ultra-high stability, which impedes thermal runaway reactions that can lead to unplanned production outages. The exceptional selectivity and consequent stability of OleMax 260 ensures reliable, on-specification performance over an unprecedentedly wide operating range, even at the extremely low CO levels typical of new cracking furnace technologies. A further advantage of OleMax 260 is a faster, more sustainable start-up. The catalyst’s simplified streaming procedure significantly reduces normal start-up-relat- ed hydrocarbon flaring and time to on-specification ethylene production. OleMax 260 is optimized to operate in de-ethanizer overhead hydrogenation process configurations. It can be used in a new build or as a drop-in solution in an existing facility.
The first commercial start-up of OleMax 260 has been successfully achieved at the new ethylene production plant of The Dow Chemical Company in Freeport, TX. To date, this state-of-the-art catalyst has delivered the superior performance and benefits expected. Doug May, Business President for Dow Olefins Aromatics, and Alternatives stated: OleMax 260 has shown robustness and resilience to process variability while providing expected raw material yields and selectivity.”
OleMax 260 is the latest innovation in the range, tailor-made for the industry-preferred front-end process for the selective hydrogenation of acetylene to ethylene, which serves as a feedstock for a variety of plastics.
