После предварительной подготовки ее образцов путем промывки водой (опока I), прокалки при температуре 500 °С (опока II), обработки HCl (опока III) или обработки HCl и прокалки при 500 °С (опока IV) на них в процессе низкотемпературного горения смеси нитратов металлов и мочевины была нанесена активная фаза (АФ) состава 5 мас. % Co + 5 мас. % Mn в пересчете на металлы. Образцы носителя и катализатора исследовались методами РФА и SEM/EDS, измерена удельная поверхность по БЭТ. Показано, что основными фазами в составе носителей и катализаторов являются различные модификации SiO2 , а также Na-, Ca- и Mg-алюмосиликаты. Компоненты АФ вследствие их низкого содержания в виде оксогидроксида кобальта и манганита калия были обнаружены только на двух образцах катализаторов. Согласно данным SEM/EDS в ходе обработки опоки и после нанесения АФ исходные наноразмерные сотовые структуры на поверхности практически полностью разрушаются. Имеет место неравномерность элементного состава на поверхности разных гранул как носителя, так и катализатора, связанная, по-видимо­му, с неоднородностью природной структуры опоки. Установлено, что по мере усложнения обработки опоки ее удельная поверхность монотонно возрастает в 3 раза – с 21,0 до 64,1 м2/г. С другой стороны, удельная поверхность катализаторов на основе этих образцов опоки изменяется нерегулярно. Испытания полученных катализаторов в процессе глубокого окисления СО и пропана в интервале температур от 150 до 540 °С выявили их достаточно высокую активность, причем наилучшие характеристики показал катализатор на основе промытой водой опоки без последующей обработки. На этом образце 100 %-ная конверсия СО была получена уже при T = 500 °С, а конверсия пропана при 540 °С достигла 97 %. Таким образом, природная опока с минимальной обработкой может служить эффективным носителем катализаторов глубокого окисления СО и угле­водородов.</p></abstract><trans-abstract xml:lang="en"><p>Natural opoka from the Taskalin deposit in the Republic of Kazakhstan was used as a support for Co–Mn catalysts in the deep oxidation of CO and hydrocarbons. After preliminary preparation of the opoka samples by water washing (opoka I), calcination at 500 °C (opoka II), HCl treatment (opoka III), or combined HCl treatment and calcination at 500 °C (opoka IV), an active phase (AP) consisting of 5 wt. % Co + 5 wt. % Mn (based on metals) was applied via low-temperature combustion of a metal nitrates and urea mixture. The support and catalyst samples were analyzed using XRD and SEM/EDS, and their specific surface area was measured by the BET method. The primary phases identified in the support and catalyst compositions were various modifications of SiO2 , as well as Na-, Ca-, and Mg-aluminosilicates. Due to their low content, AP components in the form of cobalt oxyhydroxide and potassium manganite were detected only on two of the catalyst samples. According to SEM/EDS data, the original nanoscale honeycomb structures on the opoka surface were almost completely destroyed during opoka processing and after AP application. Elemental composition showed notable variability across different granules of both the support and the catalyst, likely due to the natural structural heterogeneity of opoka. It was established that as the complexity of opoka treatment increased, its specific surface area tripled, from 21.0 to 64.1 m2/g. In contrast, the specific surface area of catalysts based on these opoka samples varied irregularly. Testing of the resulting catalysts in the deep oxidation of CO and propane over a temperature range of 150–540 °C revealed substantial activity, with the best performance observed in the catalyst based on water-washed opoka without further treatment. This sample achieved 100 % CO conversion at T = 500 °C and 97 % propane conversion at 540 °C. Thus, natural opoka with minimal processing can serve as an effective support for deep oxidation catalysts for CO and hydrocarbons.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>опока</kwd><kwd>носитель</kwd><kwd>низкотемпературное горение</kwd><kwd>Co–Mn-катализаторы</kwd><kwd>оксид углерода</kwd><kwd>пропан</kwd><kwd>глубокое окисление</kwd></kwd-group><kwd-group xml:lang="en"><kwd>opoka</kwd><kwd>support</kwd><kwd>low-temperature combustion</kwd><kwd>Co–Mn catalysts</kwd><kwd>carbon monoxide</kwd><kwd>propane</kwd><kwd>deep oxidation</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках Госзадания ИСМАН и при финансовой поддержке АО Центр международных программ «Болашак» Республики Казахстан.</funding-statement><funding-statement xml:lang="en">The work was carried out within the framework of the State Assignment of ISMAN and with the financial support of JSC Center for International Programs “Bolashak” of the Republic of Kazakhstan.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Gandhi D., Bandyopadhyay R., Soni B.
