   <abstract xml:lang="ru">
    <p>Установлено, что для K-β&quot;Fe2O3 максимальна вероятность реализации активных центров, представляющих собой кластер, состоящий из ионов калия, железа 3+ и 2+, кислорода. Неотъемлемым атрибутом K-β&quot;Fe2O3 как главного каталитически активного компонента является способность к самовоспроизводству и саморегуляции в условиях реакционной среды. Рассматриваемый тип катализаторов можно назвать «катализатор с постоянно мигрирующим промотором».&#13;
Полиферрит служит проводником щелочного промотора. Источником калия может быть моноферрит, сосредоточенный в глубине гранул катализатора, например, на внутренней поверхности закрытых пор. Полиферриты являются твердыми электролитами с катионным типом проводимости и обеспечивают не только доставку промотора в заданное место по встроенным в кристаллическую структуру каналам, но и его регулярное размещение в составе активных кластеров. &#13;
K-β&quot;Fe2O3 способен размещать в своей структуре легирующие добавки. Только в этом случае крайне малые количества вводимого агента могут сильно менять свойства системы. Если поверхность K-β&quot;Fe2O3 подвергается химическом диспергированию в реакционной среде, образуя при этом каталитически активную короткоживущую субстанцию, наногетерогенную смесь моноферрита и магнетита, то перестройка протекает не хаотично. Исходная структура-матрица способствует регулярному размещению наноразмерных компонентов, составляющих каталитически активную субстанцию, что позволяет сохранить высокую концентрацию активных центров при локальном изменении фазового состава.</p>
   </abstract>
   <trans-abstract xml:lang="en">
    <p>It was found that for K-β&quot;Fe2O3 the maximum probability of realization of the active centers representing a cluster consisting of potassium ions, iron 3+ and 2+, and oxygen. The ability to self-reproduction and self-regulation in the reaction medium is an integral attribute of K-β&quot;Fe2O3 as the main catalytically active component. This type of catalyst can be called a &quot;catalyst with a permanently migrating promoter&quot;.&#13;
Polyferrite serves as a conductor of the alkaline promoter. The monoferrite concentrated in the depth of the catalyst granules, for example, on the inner surface of closed pores can be a source of potassium. Polyferrites are solid electrolytes with a cationic type of conductivity and provide not only the delivery of the promoter to a required location through channels embedded in the crystal structure, but also its regular placement in the composition of active clusters.&#13;
K-β&quot;Fe2O3 is able to place the alloying additives in its structure. Only in this case, extremely small amounts of injected agent can greatly change the properties of the system. The rearrangement is not chaotic, if the K-β&quot;Fe2O3 surface is chemically dispersed in the reaction medium to form a catalytically active short-lived substance - a nanoheterogeneous mixture of monoferrite and magnetite.</p>
