Аннотация
Monolith sorbents/catalysts that have potential in simultaneous removal of H2S and NH3 from hot fuel gas were developed. Preparation methodology and composition of supported honeycomb sorbents/catalysts, based on manganese oxides modified by Fe and Cu oxides, have been optimized. Impregnated and washcoated monolith catalysts were tested in ammonia high temperature decomposition and H2S sorption. Approaches for improving the thermal stability and catalytic activity under reaction conditions are described.
