FIELD : chemistry.
SUBSTANCE : method for reducing the amount of sulfur in a sulfur-containing, oil-containing, composition includes the steps of : a) obtaining a sulfur-containing composition; and b) bringing the sulfur-containing composition into contact with an oxidizer and an oxidizing catalyst, wherein the oxidating catalyst has the formula M11-xM3xM2O3, where M1 is a rare earth element, M2 - transition metal, M3 - Ca or Sr, and x belongs to the range of 0.01 to 0.80. The composition applicable to reduce the amount of sulfur contains an oxidizing agent and an oxidizing catalyst, wherein the oxidizing catalyst has the formula M11-xSrxM2O3, where M1 is a rare-earth element, M2 - transition metal, and x belongs to the range of 0.01 to 0.80, and the oxidizer contains H2O2, acetic acid, tert-butylhydrogen phosphate (TBHP), formic acid, sulfuric acid, nitric acid, or a combination thereof.
EFFECT : effective reduction of the sulfur content of the oil-containing composition.
