      <abstract xml:lang="ru">
        <p>Удаление сероводорода из горячего промышленного газа предлагается производить при температуре 200-300 °C с последующим взаимодействием с Fe2O3. Для этого были предложены сорбенты: смеси оксида железа и летучей золы; оксида железа и пемзы; нескольких образцов красного шлама (остатки обработки бокситов, который также содержит оксид железа). Для предотвращения образования пыли и потери поглощающей способности сорбенты были сформированы в пористые гранулы с присутствием других металлических оксидов. Материалы, используемые в этом исследовании, получали следующим способом: смешиванием Fe2O3 с летучей золой; путем спекания смеси и красных шламов. Смесь содержит оксид алюминия и диоксид кремния, которые могут действовать как матричные формирователи и оксиды щелочных металлов, а также как флюсы для снижения температуры при спекании материалов. После насыщения образцов серой сорбент помещали в емкость для продувания, где при температуре 600-700 °C протекала десорбция до первоначального свежего состояния пропусканием воздуха через слой сорбента. В процессе этой операции освобождался диоксид серы и повторно образовывались реакционно-способные оксиды металлов. В ходе десорбции появилось небольшое количество элементарной серы и серной кислоты. Абсорбционная способность была получена при более высоких температурах, эффективность удаления H2S составляла от 95 до 99,9 %. Данную технологию очистки воздуха рекомендуется использовать на металлургических участках с повышенным атмосферным загрязнением, таких как грануляция расплавленных доменных шлаков.</p>

      <abstract xml:lang="en">
        <p>Authors suggest removing hydrogen sulfide from the hot industrial gas at temperatures 200-300 °C and its subsequent interaction with Fe2O3. For this purpose the following sorbents have been proposed: a mixture of iron oxide and fly ash; iron oxide and pumice; different samples of red mud (bauxite treatment residues containing iron oxide). To prevent dusting and loss of absorbing capacity, the sorbents were shaped into porous granules with other metallic oxides. Materials utilized in the study were obtained the following way: mixing of Fe2O3 with fly ash; sintering of the mixture with red mud. The blend contains aluminum oxide and silica, which can act as matrix shapers, alkali oxides and fluxing agents that reduce the temperature during metal sintering. After the samples had been saturated with sulfur, they were positioned in a venting reservoir, where under the temperature 600-700 °C desorption to the initial state occurred by means of passing an air flow through the sorbent layer. In the process of this operation, sulfur dioxide was released and reactive metal oxides re-emerged. Desorption also generated a small amount of elemental sulfur and sulfuric acid. Absorbing capacity was assessed at higher temperatures, efficiency of H2S removal reached 95-99.9 %. Proposed technology of air cleaning is recommended to use in metallurgic processes with elevated atmospheric pollution, e.g. granulation of melted blast-furnace slag.</p>
