METHOD AND DEVICE FOR RAPIDLY CHARACTERISING AND QUANTIFYING SULPHUR IN SEDIMENTARY ROCKS AND PETROLEUM PRODUCTS

摘要

The invention relates to a method and to a device for characterising and quantifying sulphur in a sample of sedimentary rock or petroleum product, said method comprising the following steps: heating said sample in a pyrolysis oven (1) in an non-oxidising atmosphere, oxidising a portion of the pyrolysis effluents and continuously measuring the amount of SO₂ generated by said pyrolysis after the oxidation, and transferring the pyrolysis residue of said sample into an oxidation oven (11) and continuously measuring the amount of SO₂ contained in the effluents resulting from said oxidation heating.
