Use of dark heavy oil components as a catalyst in the oxidative purification of hydrocarbonic compositions from hydrogen sulphide and light mercaptans, catalyst based on dark heavy oil components and process for oxidative purification of hydrocarbonic compositions from hydrogen sulphide and light mercaptans

摘要

The invention relates to the oxidative purification of hydrocarbonic compositions from hydrogen sulphide and light mercaptans in the presence of a catalyst and may be used in oil-and-gas, oil-refining, petrochemical industry and other branches of industry.The use of dark heavy oil components is proposed as a catalyst in the oxidative purification of hydrocarbonic compositions from hydrogen sulphide and light mercaptans. The catalyst is a residue obtained upon distillation from oil of fractions at a boiling temperature of up to 350°C and containing copper and/or vanadium in an amount of at least 0.005 mass %.The process for purification of hydrocarbonic compositions from hydrogen sulphide and light mercaptans provides for the oxidation of sulphur-containing compounds with oxygen from the air or oxygen-containing gas at temperatures from 55°C to 135°C in the presence of the above catalyst.
