Abstract (en)
[origin: EP0638628A1] Process for sweetening a petroleum cut containing mercaptans in which the said petroleum cut is subjected to oxidation conditions by being passed in the presence of air in contact with a porous catalyst, the said process being characterised in that the said catalyst includes from 10 to 98 % by weight of at least one inorganic solid phase consisting of an alkali metal aluminosilicate which has an Si/Al atomic ratio lower than or equal to 5, from 1 to 60 % by weight of active carbon, from 0.02 to 2 % by weight of at least one metal chelate and from 0 to 20 % by weight of at least one inorganic or organic binder, has a basicity determined according to ASTM standard 2896 higher than 20 milliequivalents of potassium hydroxide per gram and a BET total surface greater than 10 m<2>g<-1>, and contains within its porosity a permanent aqueous phase representing from 0.1 to 40 % by weight of the dry catalyst.
