Possibilities of High-Temperature Desulphurization and Dechloration of a Producer Gas

According to thermodynamic calculations Ce2O3 exerts the highest affinity to H2S and is capable of deep desulfurization at temperatures up to 800 K. Ce2O3 can be stabilized by La2O3 or MnO addition under common reduction conditions. Therefore Ce2O3 sorbents doped by La2O3 seem to be promising producer gas sorbents
