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

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 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 applied components are the residue, having a copper and/or vanadium content of at least 0.005 mass %, obtained as a result of distillation from oil of fractions with a boiling temperature of up to 350°C.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.
