Sažetak
The coke used as feedstock in the production of graphite electrodes may contain only limited amounts of metallic microconstituents. One of the procedures for their separation from carbon materials is high-temperature treatment. This paper deals with the results of investigations of the mechanism of nickel separation from petroleum cokes as real carbon systems during high-temperature treatment up to 2400°C. The investigations were performed on coke samples obtained from various precursors from the Moslavina basin oil, whose content of nickel is known to be larger than that of the other originally traced metals. The identification of the nickel compounds in cokes heated to temperatures between 1250° and 2400°C points to alternation of their chemical composition in terms of formation of thermally more or less unstable compounds. With a rise in temperature, the nickel mass fraction diminishes, as do relative reflex intensities of the identified compounds. A relationship was established between the efficacy of nickel separation during high-temperature treatment (HTT) up to 2400°C, on the one hand, and its mass fraction and the type of chemical compounds present in petroleum cokes, on the other.
