Catalysts Ultra-High-Performing Acetylene Selective Hydrogenation Catalysts
Clariant has recently announced the launch of an expanded portfolio of acetylene selective hydrogenation catalysts in China. The Ole Max catalyst series is highly appreciated in the industry, providing high performance as well as operating flexibility.
The organisation now offers three tailor-made catalysts for the industry-preferred ‘front-end’ process configuration for the selective hydrogenation of acetylene to ethylene:
Ole Max 252 offers high selectivity to ethylene and operational stability over wide temperature ranges. It is the cost-effective option for budget-minded ethylene producers as its low-bulk-density carrier offers cost savings on volumetric basis, explains the firm.
Like the whole catalyst family, it can be used in a new build or as a drop-in solution in an existing facility. It is optimised to operate in de-ethanizer and de-propanizer overhead as well as in raw gas hydrogenation process configurations.
Ole Max 254 delivers high selectivity while showing lower sensitivity towards CO swings. This allows stable operation over increased temperature ranges. According to the company, the excellent durability of its carrier allows operating Ole Max 254 through more than one cycle after ex-situ regeneration. The catalyst is suitable for de-ethanizer and de-propanizer plant configurations.
Ole Max 252 and Ole Max 254 are already installed in numerous world-scale ethylene production facilities proving outstanding performance.
Ole Max 260, the latest innovation in the range, provides a near perfect selectivity to ethylene (close to 100 % when operated properly), resulting in significant economic benefit for producers, states the firm. 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 Ole Max 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 explains that a further advantage of Ole Max 260 is a faster, more sustainable start-up: The catalyst’s simplified streaming procedure significantly reduces normal start-up-related hydrocarbon flaring and time to on-specification ethylene production.
