Abstract
A catalyst for alkali-free purification of oil raw material, consisting of a metalocomplex selected from the group consisting of a solid metalocomplex and a liquid metalocomplex with a general formula (CuIICl)2O(L1)2-4(L2)1-4, where L1 is amino alcohol L2 is acetonitrol or single atom alcohol.
Claims2
A method of purification of pure fractions and gas condensate from mercaptans by processing of oil raw material with air in the presence of a catalyst, comprising the steps of using a catalyst for alkali-free purification of oil raw materials, consisting of a metalocomplex selected from the group consisting of a solid metalocomplex and a liquid metalocomplex with a general formula (CuIICl)2O(L1)2-4(L2)1-4, where Li is aminoalcohol, L2 is acetonitryl or single atom alcohol, wherein as the aminoalcohol a compound of a general formula N(R1)(R2)(R3)(OH)1-3 is utilized, where R1=C2H4, R2=H, C2H4 , C2H5, R3 =H, C2H4, CnH2n+1, where n=2-17.
A method of purification of pure fractions and gas condensate from mercaptans by processing of oil raw material with air in the presence of a catalyst, comprising the steps using a catalyst for alkali-free purification of oil raw materials, consisting of a metalocomplex selected from the group consisting of a solid metalocomplex and a liquid metalocomplex with a general formula (CuIICl)2O(L1)2-4(L2)1-4, where Li is aminoalcohol, L2 is acetonitryl or single atom alcohol, wherein as the single atom alcohol a substance selected from the group consisting of isopropanol, butanol, isobutanol and pentanol is utilized.
