Depending on the desired carbon monoxide conversion, the sour shift process can be carried out in either one or several steps. Multiple reactors, typically with cooling between each bed, are required for high carbon monoxide conversion due to the equilibrium characteristics of the sour shift reaction.
The high performance of Topsoe’s sour shift guard material (GSSK) and catalyst (SSK-10) is well-proven under all operating conditions, and SSK series catalysts have consequently been installed in some of the world’s largest sour shift installations.

Catalyst Loading
All plants – even those with lots of turnaround experience – can run into trouble during loading. When a problem occurs, it can lead to longer turnarounds and, in the worst case, result in an underperforming catalyst. That makes proper loading an important step in profitable plant operation.
