FIELD: chemistry. ^ SUBSTANCE: invention relates to methods of preparing a catalyst, for example for oxidising ammonia and hydrocarbon-containing gases and can be used primarily in production of nitric acid. The method of preparing catalyst involves initial heat treatment of an inert carrier in a current of air or oxygen, depositing an intermediate coating from aluminium oxide or one or more platinum group metals onto the surface of the said carrier, and drying, wherein the intermediate coating of aluminium oxide is deposited from a gel, obtained by combining initial components in water in the following ratio, wt %: aluminium nitrate nonahydrate - 3-10; aqueous ammonia (25% concetration) - 1.7-5.5; ionogenic surfactant 0.25-1.0; water - the rest up to 100. ^ EFFECT: preparation of a catalyst with longer service life, which increases efficiency of production and reduces its cost, improves regeneration and recycling of the catalyst. ^ 2 ex |
