Method and device for fast sulfur characterization and quantification in sedimentary rocks and petroleum products

摘要

The invention relates to a method and to a device for sulfur characterization and quantification in a sample of sedimentary rocks or of petroleum products wherein the following stages are carried out: heating said sample in a pyrolysis oven (1) in a non-oxidizing atmosphere, oxidizing part of the pyrolysis effluents and continuously measuring the amount of SO₂ generated by said part after oxidation, then transferring the pyrolysis residue of said sample into an oxidation oven (1′) and continuously measuring the amount of SO₂ contained in the effluents resulting from said oxidation heating.
