Abstract: Desulfurization of Ni pyrrhotite by steam in the microwave field was studied. According to the experimental data, the desulfurization rate by microwave heating is faster than that by conventional one. The desulfurization reaction is in a non-isothermal state and in a diffusion control because of the effect of chemical reaction heat, phase formation and intrinsic properties of materials of microwave absorbability. When the flow rate of steam was in the range of 180 similar to 220 mL/min, the temperature and desulfurization rate approached to a maximum and the activation energy to a minimum.
