The zeolite is exemplifying promising material as the DESONOX type of catalysts. Main goal of this work is preparation of catalyst. Support was impregnated with cobalt or nickel ions by different methods: wet impregnation, double impregnation, adsorption from water and water-saccharose solution of cobalt and nickel ions. The catalysts were physical-chemical characterized (texture, structure). The catalytic properties were studied by reaction of burn with coal in the flow reactor. Hard coal from mine 'Julian' and 'Bogdanka' from Poland with or without the catalysts addition were burnt in an atmosphere of air at 1123 K during 4 hours and using an electric furnace. The mass ratio of the DESONOX catalyst added to the investigated samples of the hard coal was 1:500.
