The paper presents relatively simple but reliable laboratory method for the preparation of manganese oxides alumina supported catalysts for highly concentrated hydrogen peroxide decomposition. The number of batches of the pellet catalysts were prepared by simple wetness, impregnation method. In all cases the researched samples of the catalysts were impregnated with a precursor solution of potassium permanganate resulting in the formation of manganese oxide catalyst after the baking process. The primary assessment criterion performed after the preparation was percentage catalyst loading with respect to weight. The effect of various support kinds and the modifications of preparation process on the final properties of the catalyst has been evaluated. The activity and the durability have been assessed through the hot tests. The practical validation and application of the catalyst is its utilisation in the fixed catalyst bed in the rocket propulsion devices.

Artykuł opisuje stosunkowo prosty i niezawodny sposób laboratoryjnego wytwarzania katalizatorów rozkładu wysoko stężonego nadtlenku wodoru. Każdą partię katalizatorów wytworzono w procesie impregnacji i spiekania. Tlenek glinu w postaci pelletów impregnowano w roztworze nadmanganianu potasu, następnie poddawano go spiekaniu i otrzymywano gotowy katalizator. Katalizatory po procesie poddawano ocenie zawartości fazy aktywnej, wpływu prekursorów oraz modyfikacji sposobu wytwarzania na jego trwałość.
