Abstract:
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.
