В результате обжига некоторое количество остаточной углекислой соли двухвалентного марганца остаетс  нетронутым, что дает особый физический вид двуокиси марганца в виде элементарных зерен размером до 1 мк в виде кристаллов, сохран ющих ромбоэдрическую структуру образующей углекислой соли закиси марганца.(c) A mixture of the corresponding metal carbonate salts or bicarbonates containing about 80% of carbonate salt of two-ivolite ivtapraiiina, 10% copper bicarbonate and 10% nickel bicarbonate. As a result of roasting, some amount of the residual carbonate of divalent manganese remains intact, which gives a special physical appearance of manganese dioxide in the form of elemental grains up to 1 micron in the form of crystals that preserve the rhombohedral structure forming the carbonate of manganese oxide.

Эти окиси согласно изобретеи но иолучаютс  иутем реакции обжига с достуном воздуха при 600°С смеси соответствующих металлических уг,1ек 1слых солей и гидрокарбонатов, содержащей около 80% углекислой соли двухвалентного марганца, 10% гидрокарбоната медн и 10% гндрокарбоната никел . Эта темиерат )фа обжига обеспечивает полное преобразование углекислых солей (карбонатов) и гпдрокарбонатов смеси в активные окислы в составе ко11ечио1-о каталитического продукта. These oxides are invented in accordance with the invention and are roasted with air at 600 ° C with a mixture of the corresponding metal carbon, 1 c 1 salt and bicarbonate containing about 80% carbonate of divalent manganese, 10% bicarbonate of nickel and 10% carbonate. This terarat of the firing process ensures the complete conversion of carbonate salts (carbonates) and gpdrocarbonate mixtures into active oxides in the composition of a cochio1-o catalytic product.

Эффективность этого разложеии  можег быть констатироваиа ио меньшей мере трем  снособами. Первый состоит в нсчезновеппи запаха обрабатываемых наров. Это средство  вл стс  чрезвычайно эффективным, поскольку такие вещества, как известно, имеют невыносимый запах, даже если нх содержание в газах достигает несколько миллионных долей на кубический метр.The effectiveness of this decomposition can be determined by at least three ways. The first is to treat the smell of processed bunks. This agent is extremely effective, since such substances are known to have an unbearable odor, even if their content in gases reaches a few ppm per cubic meter.

BTopoii способ состоит в количествепнои оценке возможных остаточных колнчеств этих веществ ирн помощи трубки Драгера. При иомощи этого способа осуществл етс  визуальный контроль эффективности реакции с помондью окрашенных реактивов.The BTopoii method consists in quantifying the possible residual properties of these substances using the Drager tube. With the aid of this method, a visual control is carried out of the effectiveness of the reaction with a pond of colored reagents.

Наконец, третий снособ состоит в хроматограф Н1 газовой фазы, осуществл емой на обрабатываемом газе до и иосле его прохожде 1и  через катализатор.Finally, the third removal method consists in a gas phase chromatograph H1 carried out on the treated gas before and after passing through the catalyst.

It precipitates the content of monomer, manganese, copper and nickel carbonates. 400 g of cement or clay-based refractory material are added to it, turning it into a more or less thick jasta, depending on the form requirements that will be imparted to the final catalytic product. Easily flowing jasta facilitates the infiltration of chensty.x or linen-like carrier materials. The average consistency allows the paste to be applied to metal.

The thick jasta allows you to cast or extrude any desired geometric shapes from it: dns, kiripchi, granules, sticks, rings. After combining with cement or a refractory base material based on the mixture formed in such a way, with or without a carrier base, they are calcined in a ventilated drying chamber or furnace at a temperature of EPO, for the following type of oxidizing cements that are supported by cement to be converted into oxides:
