Determination of sulfur and trace elements in petroleum coke by X-ray fluorescent spectrometry

Abstract

The content of sulfur, vanadium, and other trace elements in petroleum coke is determined by means of X-ray fluorescent spectrometry, without preliminary incineration of the samples. The inorganic composition (the content of sulfur and trace elements) is studied for ten petroleum-coke samples obtained in different industrial and laboratory conditions on the basis of West Siberian petroleum derivatives (heavy tars, asphalt, heavy catalytic-cracking gas-oil, and a mixture of heavy tars with the heavy gas-oil). The content of S, V, Ni, Ca, Si, Fe, Al, Mg, K, Na, Cu, Cr, and Zn is determined in all the samples.
