Claims (9)
1. Способ каталитического восстановления сернистого газа из газовой смеси, содержащей по меньшей мере 10 об.% воды, согласно которому газовую смесь пропускают через стойкий к сере гидрогенизирующий катализатор в сульфидной форме с объемной скоростью, составляющей, по меньшей мере, 2000 ч-1, в присутствии восстанавливающего компонента, предпочтительно, по меньшей мере, частично состоящего из водорода, с молярным отношением восстанавливающего компонента и сернистого газа, составляющим более 10 и вплоть до 100, при температуре от 125 до 300°С, затем газовую смесь, после указанного восстановления, пропускают через сухой окисляющий слой для окисления сернистых соединений, более конкретно, сероводорода, с получением элементарной серы.
2. Способ по п.1, в котором катализатор удерживается на материале-носителе, по существу не обладающем активностью в реакции Клауса и имеет, по меньшей мере, один сульфидный гидрогенизационный компонент, нанесенный на поверхность материала-носителя.
3. Способ по п.2, в котором гидрогенизационный компонент выбирается из группы металлов групп VIB, VIIB и VIII Периодической таблицы химических элементов.
4. Способ по п.3, в котором гидрогенизационный компонент основан на молибдене, и/или вольфраме, и/или кобальте.
5. Способ по п.4, в котором гидрогенизационный компонент является катализатором, основанным на молибдене или вольфраме на носителе из кремнезема, предпочтительно содержащим 0,1-50 мас.% молибдена или вольфрама.
6. Способ по пп.2-5, в котором материал-носитель подбирают из группы, состоящей из кремнезема, α-глинозема, алюмосиликата, диоксида циркония, углерода (волокна), карбидов, фосфатов (таких как фосфат алюминия).
7. Способ по пп.1-6, в котором объемная скорость составляет менее 12000 ч-1, предпочтительно, менее 10000 ч-1.
8. Способ удаления загрязняющей серы из газовых смесей, включающий следующие стадии: преобразование части сероводорода в сернистый газ, введение смеси в реакцию Клауса, по меньшей мере, в одном каталитическом реакторе, извлечение сернистого газа, присутствующего в полученной газовой смеси, с использованием способа по любому из пп.1-7, избирательное окисление сероводорода, присутствующего в полученной газовой смеси, в элементарную серу.
9. Способ по п.8, в котором операцию избирательного окисления осуществляют в сухом окисляющем слое.
