CAPTO method application to the quality assessment of Slovak brown coal
This paper describes the principle and application of CAPTO (Controlled - atmosphere programmed - temperature oxidation) method for the sulphur content valuation in coal. The principle of CAPTO consists in mixing the coal with an inert material (WO3) and oxidation of the sample by a linear increase of temperature to 1000oC. The evolved gases (CO2, H2O, SO2 and NO2) are analyzed by infrared sensors. The method enables the determination of different sulphur forms (sulphidic, elemental, sulphate, organic aromatic and organic non-aromatic), hydrogen, carbon and humidity. The results on Americal coal Illionois No. 6 and Slovakian brown coal Nováky serve as an illustration of the CAPTO method possibility.
