Abstract

In our thermodynamic theoretical study we concentrated our attention on thermodynamics of gas-solid desulfurization reactions (H₂S, COS, thiophene), properties of sorbents (melting point evaporation), attainable equilibrium sulfur compounds concentrations in gas at temperature 500–1100 K (227-827 °C) under conditions typical for producer gas composition. Similarly removal of HCl and HF by Ce, La, Zn, Mn and Ni oxides based sorbents is described and possible interferences in simultaneous sorption of HCl or HF with H₂S are analyzed. Suitable conditions and sorbents are suggested for deep removal of sulfur compounds in presence of HCl. Conditions for efficient preliminary removal of HCl and HF by alkali-based sorbents (NaHCO₃, K₂CO₃, Ca(OH)₂, CaCO₃) are suggested and possible interferences caused by H₂S are analyzed in terms of attainable equilibrium concentrations of HCl and HF in presence of H₂S. Properties of La and Ce-based sorbents for sulfur compounds are compared with Zn, Mn and Ni based sorbents in terms of efficiency and interferences caused by presence of hydrogen-halides (HCl, HF).
