  • Process for the removal of COS and HS from a synthesis gas stream comprising HS and COS
    Patent number: 7846325
    Abstract: The invention provides a process for the removal of COS and H2S from a synthesis gas stream comprising COS and H2S, the process having the steps of: removing H2S 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 H2S 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 H2S; and removing H2S from the second synthesis gas stream by contacting the second synthesis gas stream with a second solid adsorbent in a H2S removal zone to obtain a third synthesis gas stream depleted of H2S and depleted of COS to very low levels.
