Experimental study on preparation of prebake anodes with high sulfur petroleum coke desulfurized at high temperatures

Abstract

High sulfur petroleum cokes were calcined in a high temperature furnace to reduce the sulfur content 9 during the prebaked anode production, and that can be good for reducing environment pollution. The preparation test and performance analysis of anodes were carried out. The ways of injecting the desulfurized coke and its influence on quality of the anode are discussed. The results show that although the high temperature treatment greatly reduces the sulfur content of the high-sulfur petroleum coke, it has a negative effect on the microstructure and properties of the anode, and the desulfurized coke cannot be used to product anode in large quantities. A certain proportion of the desulfurized coke can be used with little effect on the anode properties. The present work can provide a reference for the application of high temperature desulfurized petroleum coke in anode production.
