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.
