    Interferences and Thermodynamic Limits for Producer Gas Desulfurization, de-HCL and de-HF by Ba, Ce and La-based Sorbents

  • Original language description

    We have focused in our study on thermodynamic analyses of gas desulfurization process (removal of H2S) by selected solid sorbents (BaO/BaCO3, CexOy , La2O3) and comparison with ZnO-based sorbents. In the case of hydrogen-halides we have studied sorptionthermodynamics, equilibria and interferences in H2S sorption by BaO/BaCO3, Ce, La and ZnO-based sorbents caused by presence of HCl and HF in the gas. The results indicate that the best sorbent for sulfur compounds at temperatures between 800 K and 1000 Kis La2O3. Efficiency of CexOy based sorbents is sensitive to reduction conditions, and temperature. The promising Ba-based sorbents are dependent on appropriate solid solution form stabilizing BaO for its sorption applications. The La2O3 and CexOy basedsorbents suffer from significant interferences caused by higher concentrations of HCl and HF in gas at temperatures below approx.. 900 K. The upstream deep removal of HCl (HF) from producer gas by alkaline/alkaline earth-based sorbents i
