Analysis of Electrochemical Mechanism of Electrolyte and Coal

Abstract:

In order to study the electrochemical performance of coal in the HCL electrolyte system, researchers prepared the chemically modified carbon paste electrode, measured the volt-ampere curves and Tafel curves of the samples and analyzed the mechanism of the electrochemically catalysis of oxidation of coal. The studies indicate that what occurs to the coal sample in the process of electrolytic sulfur removing is a quasi-reversible diffusion controlled process. In the beginning of the sulfur removing, the rate of electrolytic corrosion is fast, in which oxidation on the anode denominates, and the cathode plays a role of reduction in the late period.
