A mechanistic study of the deactivation by hydrocarbon fouling of front end acetylene hydrogenation catalysts and the effect of carbon monoxide incorporation
- ICI Katalco Research, Technology and Engineering, Billingham (United Kingdom)
Front and tail end selective acetylene hydrogenation catalysts show activity loss with time-on-line caused by the accumulation of hydrocarbon species on the surface of the catalyst. Although in front end processes this de-activation rate is considerably lower than for a tail end configuration, the rate is nonetheless significant. The plant downtime while regeneration is undertaken or the need for reserve reactors can add important cost penalties to the plant operation. The mechanism of the de-activation is complex involving reductive acetylene oligomerization and carbon monoxide incorporation via several palladium catalyzed carbonylation reactions. This paper describes research directed toward elucidating both the chemistry of the hydrocarbon synthesis on plant and laboratory catalysts and the development of techniques to determine key intermediates in these reactions.
