摘要：
The invention provides a process for the removal of COS from a first synthesis gas stream comprising COS and H2S, the process having the steps of: (a) 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; (b) removing H2S from the second synthesis gas stream by contacting the second synthesis gas stream with a solid adsorbent in a H2S removal zone to obtain a third synthesis gas stream depleted of H2S and depleted of COS
