C2H2 hydrogenation Last month, Clariant (Munich, Germany; www.clariant.com) launched OleMax 260, a new selective acetylene-hydrogenation catalyst, which is said to have extremely high ethylene selectivity and operational stability. Specially developed for ethylene producers with “front-end” process configurations, OleMax 260 offers a “near perfect selectivity to ethylene (close to 100%), resulting in significant economic benefit for the operator,” says Clariant. The catalyst has 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, the company adds. The catalyst’s simplified streaming procedure significantly reduces normal startup-related 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 application of OleMax 260…
