Autothermal reforming (ATR) of hydrocarbons is the most promising process for hydrogen production. This work is devoted to the study of the effect of support composition (x/Al2O3, x = CeO2, ZrO2, La2O3, Ce0.5Zr0.5O2, La2O3/Ce0.5Zr0.5O2) and preparation mode (co-impregnation, sequential impregnation) on the stability of NiPd bimetallic catalysts in the ATR of CH4. The directional regulation of Red-Ox properties, structure and particle size of Ni-containing active component by means of variation of support composition and preparation mode provides the development of an active and stable NiPd bimetallic catalyst. Developed catalyst formulation 0Ni0.2Pd/10Ce0.5Zr0.5O2/Al2O3 prepared under optimized conditions shows high activity (CH4 conversion ~100%, H2 yield > 80%), stability (time on stream 100 h), resistance to carbon formation and resistance to deactivation by sulfur. The best performance of the optimized catalyst can be associated with peculiarity of NiPd particles structure and the optimal ratio between Ni2+ species with different ability for reduction
