Abstract

THE STUDY OF PETROLEUM COKE THERMAL STABILITY AND ITS FURTHER MODIFICATION – EXPERIMENTAL APPROACH AND MODELING

Felix Yu. Sharikov*, Leading Research Scientist and Yuri V. Sharikov Professor

ABSTRACT

The methodology and results of thermal stability study for initial and modified commercial petroleum cokes are presented. TG/DSC technique was applied for an experimental study of the petroleum coke calcination and further characterization of the improved coke in an oxidation reaction. It was found that the commercial coke still contained residual volatiles in a noticeable amount. The high-temperature stability of this commercial “raw coke” to be used for electrodes formation (e.g., in silicone production furnaces) or in carbothermal processes can be further improved via its additional calcination in a tubular kiln or an electro-calcinator under specified conditions. Kinetic modeling of the calcination process was proposed and further simulation of the tubular kiln operation was done to determine the optimal conditions of its functioning. The ash quantity was estimated as close to zero that makes it especially valuable for metallurgical silicone production.
