摘要：
A process for sweetening a petroleum cut containing mercaptans, wherein said petroleum cut is subjected to oxidation conditions by its being passed in the presence of air in contact with a porous catalyst said process being characterized in that said catalyst comprises 10 to 98% by weight of at least one mineral solid phase constituted of analkaline aluminosilicate with a Si/Al atomic ratio less than or equal to 5, 1 to 60% by weight of active carbon, 0.02 to 2% by weight of at least one metal chelate and 0 to 20% by weight of at least one organic or mineral binding agent, has a basicity determined according to the 2896 ASTM standard with 20 milli-equivalents of potash per gram and a total BET surface area of 10 m.sup.2 g.sup.-1, and contains inside its pore structure a permanent aqueous phase representing 0.1 to 40% by weight of dry catalyst.
