A number of ceramic membrane reactors (CMR) of various designs and compositions for high-temperature hydrogen sulphide decomposition were studied. Two CMR types with the layered structure were used: the first type included catalyst layer, membrane support, and membrane layer, while the second one was composed of catalyst layer, membrane support, an intermediate layer, and membrane layer. It is demonstrated that the pore structure and the thickness of the membrane layer have a significant effect on permeability for H-2 and H2S. Due to the high H-2/H2S separation coefficient (more than 2.5), a significant improvement of the parameters of H2S decomposition in CMR in comparison with the flow reactor with a granulated catalyst is observed. The H2S conversion (with the formation of H-2) reaches 87 % at 900 degrees C in the CMR of the optimal composition prepared using the optimal method.
