Effect of ferric chloride on graphitization of anthracite and petroleum coke

In this paper, using ferric chloride as catalyst, the graphitization of anthracite and petroleum coke was studied. The results show that the optimum dosage of ferric chloride is 10% for the graphitization of anthracite and 7.5% for the graphitization of petroleum coke. The effect of roasting temperature on the graphitization of anthracite and petroleum coke catalyzed by ferric chloride is remarkable, and the best temperature is 1400°C in experimental temperatures. The effect of roasting holding time on the graphitization of anthracite and petroleum coke catalyzed by ferric chloride is positive, and the effect is not obvious after 120min. Under the optimal experimental conditions, the highest graphitization degree of anthracite and petroleum coke catalyzed by ferric chloride are 37.21% and 31.97%, respectively. It intimates that the catalytic effect of ferric chloride on anthracite is better than that on petroleum coke.
