The chlorination kinetics of pure vanadia was studied via isothermal thermogravimetric measurements, with CCl4, CoCl2 and Cl2 as chlorinating agents. At temperatures where chemical control was predominant, apparent activation energies of 77, 48 and 126 kJ: mol−1 were obtained for chlorination by CCl4, COCl4 and Cl2, respectively. For interpretation of the conversion vs. time curves in the whole conversion range, a non-uniform particle size distribution was assumed, where the reacting solid phase was considered to be composed of thin plates of different thicknesses. With this model, a fairly good correspondence was obtained between the measured and calculated kinetic curves. Selected thermodynamic calculation data on the V2O5 + CCl4, V2O5 + COCl2 and V2O5 + Cl2 systems are presented.
