Abstract
The invention provides a process for the removal of COS and HS from a synthesis gas stream comprising COS and HS, the process having the steps of: removing HS from a feed synthesis gas stream with a first solid adsorbent to obtain a first synthesis gas stream, converting COS in the first synthesis gas stream to HS by contacting the first synthesis gas stream with a COS-hydrolysing catalyst in the presence of water in a hydrolysis zone to obtain a second synthesis gas stream depleted of COS and enriched in HS; and removing HS from the second synthesis gas stream by contacting the second synthesis gas stream with a second solid adsorbent in a HS removal zone to obtain a third synthesis gas stream depleted of HS and depleted of COS to very low levels.
