Abstract

Изобретение относится к газонепроницаемым материалам, в твердом состоянии переработанным в мембраны для использования в каталитических мембранных реакторах, и более конкретно, к аниону кислорода в твердом состоянии и мембранам, способствующим созданию электрона, для использования в каталитических мембранных реакторах для ускорения частичного и полного окисления различных химических соединений, для разложения кислородсодержащих соединений и для отделения кислорода от других газов. Материалы в твердом состоянии для использования в мембранах настоящего изобретения включают смешанные металлоксидные соединения, имеющие броунмиллеритовую (brownmillerite) кристаллическую структуру. Каталитические мембранные реакции включают, среди других, частичное окисление метана или природного газа в синтез-газ. Мембрана в твердом состоянии для использования в каталитическом мембранном реакторе, включающая в себя поверхность восстановления, контактирующую при работе в каталитическом мембранном реакторе с кислородсодержащим газом, и поверхность окисления, контактирующую при работе в каталитическом мембранном реакторе с газом-реагентом, частичным вакуумом или газом, обедненным кислородом, при этом мембрана изготовлена из смешанного материала на основе оксида металла, имеющего броунмиллеритовую структуру и имеющего общую стехиометрическую форму AA'BB'O, где А представляет ион щелочно-земельного металла или смесь ионов щелочно-земельных металлов; А' представляет ион металла или смесь ионов металлов, где металл выбирается из группы, состоящей из металлов латанидной серии или является иттрием; В представляет ион металла или смесь ионов
