Determination of intrinsic kinetics parameters for MoO3 chlorination with Cl2 gas between 798 and 873 K

▸ Kinetics of chlorination of MoO3 was studied by thermogravimetry. ▸ The starting temperature for the reaction is determined at about 770 K. ▸ An average activation energy of 211 kJ mol−1 for the chlorination was determined. ▸ A reaction order of 1 with respect to chlorine partial pressure was obtained. ▸ A complete reaction rate equation was formulated for two MoO3 sample morphologies.
