Abstract

Method of removing mercury from a mercury-comprising hydrocarbon stream, in which the hydrocarbon stream is brought into contact with an absorbent comprising copper on a support material, wherein the hydrocarbon stream is brought into contact with the absorbent in the presence of hydrogen.

Claims

exact text as granted — not AI-modified
1 .- 8 . (canceled) 
     
     
         9 . A method of removing mercury from a mercury-comprising hydrocarbon stream, which comprises bringing a hydrocarbon stream into contact with an absorbent comprising copper on a support material, wherein the hydrocarbon stream is brought into contact with the absorbent in the presence of hydrogen, wherein the absorbent comprises from 10 to 60% by weight of copper oxide, from 0 to 40% by weight of zinc oxide, from 0 to 20% by weight of aluminum oxide, from 5 to 25% by weight of magnesium oxide, from 10 to 40% by weight of silicon dioxide, from 0 to 5% by weight of chromium(III) oxide and from 0 to 10% by weight of barium oxide. 
     
     
         10 . The method according to  claim 9 , wherein copper is present on a porous oxidic support material. 
     
     
         11 . The method according to  claim 9 , wherein the absorbent comprises from 10 to 60% by weight of copper. 
     
     
         12 . The method according to  claim 9 , wherein the hydrocarbon stream is present in liquid form. 
     
     
         13 . The method according to  claim 9 , wherein the absorbent is present as a fixed bed. 
     
     
         14 . The method according to  claim 13 , wherein the hydrocarbon stream is brought into contact with the absorbent in the upflow mode or the downflow mode. 
     
     
         15 . The method according to  claim 12 , wherein the absorbent is present in suspension in the hydrocarbon stream.
