Abstract
The reaction between zinc sulfide and water vapor is a component reaction in a new reaction scheme recently developed to transform zinc sulfide to zinc oxide through the use of lime and water vapor. The intrinsic kinetics of this reaction for ultrafinely ground (<1 μm) ZnS particles was determined by carrying out measurements in the absence of heat- and mass-transfer effects. The reaction products were identified to be ZnO and H2S. The kinetics of the reaction can be represented by \( dX_B /dt = k_1 (C_{{\text{H}}_{\text{2}} {\text{O}}} - C_{H_2 S} /K_e )(1 - X_B )[ - \ln (1 - X_B )]^{1 - 1/n} ;1023 < T < 1160K \) and 3.94<C H2O <9.84 mol/m3 withn=1.28 andk 1=45.3 exp(−14600/T) m3·mol−1·s−1, whereX B is the fractional conversion.
