A model for the intrinsic kineticparameters of the direct reduction of MoS2 with hydrogen

This study was carried out in order to obtain intrinsic kinetic parameters for the reaction between molybdenum disulfide and hydrogen. The experiments were performed using thermogravimetry within the temperature range of 1073 - 1223 K and at atmospheric pressure. The reaction was conducted by applying thin pellets and the data obtained were analyzed using a nucleation and growth kinetic model. The reaction was first order with respect to the gas phase reactant. The activation energy for the reduction process was determined to be 135.4 kJ mo-1.
