A method for the demercaptanization of petroleum distillates

The demercaptanization of petroleum distillates may be carried out by means of the oxidation of the mercaptans contained therein using the oxygen in the air, at a temperature of about 80 to about 220 DEG C, in the presence of about 0.01 to about 10.0 mass % of a water-soluble salt of copper, iron, n...

More Information
Summary:The demercaptanization of petroleum distillates may be carried out by means of the oxidation of the mercaptans contained therein using the oxygen in the air, at a temperature of about 80 to about 220 DEG C, in the presence of about 0.01 to about 10.0 mass % of a water-soluble salt of copper, iron, nickel, or cobalt, on a fibrous carbonaceous material in the form of a woven fabric, felt, rope, or twisted strand, used as a heterogeneous catalyst. The fibrous carbonaceous material used in the process contains oxides of calcium, magnesium, copper, manganese, iron, zinc, and aluminum in an amount of up to about 0.03 mass %.
