Determination of organic oxygen in petroleum cokes and coals

This paper describes a rapid and reliable methodology for the analysis of organic oxygen in petroleum cokes and coals using a pyrolysis furnace followed by IR detection, calculating the detection and quantification limits and the uncertainty of the method. The accuracy of the method has been also checked by analyzing reference materials and determining all the constituents (C, H, N, S, and ash content) of the petroleum cokes and coals analysed in this study. The organic oxygen data have been also correlated with the volatile matter as the oxygen-containing compounds constitute part of the total volatile matter and this parameter is important in the selection of coals and in the evaluation of coking of coke which will determine the use of the coke.
