Kinetics of the Chlorination of Copper (I) Sulphide by Calcium Chloride in the Presence of Oxygen

The chemism of the chlorination of copper (I) sulphide by calcium chloride in the presence of oxygen has been determined based on the thermodynamic analysis in the Cu sub(2)S-CaCl sub(2)-O sub(2) system as well as characterization of used raw materials and obtained products. The influence of tempera...

Zusammenfassung:The chemism of the chlorination of copper (I) sulphide by calcium chloride in the presence of oxygen has been determined based on the thermodynamic analysis in the Cu sub(2)S-CaCl sub(2)-O sub(2) system as well as characterization of used raw materials and obtained products. The influence of temperature (from 473 to 773 K), time (from 2 to 120 min), oxygen flow (from 20 to 100 L/h) and calcium chloride quantity (from 5 to 40%) on the chlorination degree has been investigated. Kinetic analysis and the activation energy values of 20.89 kJ/mol showed that the chlorination of copper (I) sulphide by calcium chloride in the presence of oxygen is diffusion controlled.
