Abstract
AbstractIn this work, kinetic of H2S conversion to H2 molecule on the surface of Pt(111) is studied using kinetic Monte Carlo simulation. The results of simulation were fitted to the experimental temperature‐programed desorption spectra. The good agreement between the empirical and the simulated data confirms the proposed mechanism and kinetic data (activated energies and pre‐exponential factors). The influence of variables such as temperature and concentrations of H2S and H2 on the overall results of hydrogen production is studied. The condition is proposed in which the best yield of reaction at minimum temperature is obtained. Results show that platinum is a perfect catalyst for converting H2S to H2 and it has a perfect performance (98%) after 5 μs at low temperature of 227°C.
