(54) КАТАЛИЗАТОР ДЛЯ ГАЗОФАЗНсТО ОКИСЛЕНИЯ(54) CATALYST FOR GAS-PHASING OXIDATION
КИСЛОРОДОМ ВОЗДУХА АЛИФАТИЧЕСКИХ МЕРКАПТАНОВ AIR OXYGEN OF ALIPHATIC MERCAPTANS
Насто щее изобретение относитс к катализаторам газофазного гетерогенного каталитического окислени алифатических меркаптанов в газовых смес х до элементарной серы.The present invention relates to catalysts for the gas-phase heterogeneous catalytic oxidation of aliphatic mercaptans in gas mixtures to elemental sulfur.
Известен катализатор дл очистки газов от органической серы, например,меркаптанов , на основе окиси алюмини , содержащей окиси кобальта и молибдена TilKnown catalyst for the purification of gases from organic sulfur, for example, mercaptans, based on alumina, containing cobalt oxides and molybdenum Til
Известны также катализаторы дл получени дисульфидов путем газофазного окислени меркаптанов кислородом воздуха или окислами азота, содержащие окислы меди и железа на активированном угле или термически активированном боксите 23.Catalysts for the production of disulfides by gas-phase oxidation of mercaptans with atmospheric oxygen or oxides of nitrogen containing oxides of copper and iron on activated carbon or thermally activated bauxite 23 are also known.
С целью удалени меркаптанов и других серусодержащих. соединений в процессе газофазной гетерогенной каталитической очистки воздуха, промышленных газов в качестве катализаторов, предложены окись алюмини , каолин, окислы щелочноземельных металлов и др., носители, на поверхность которых ДО ЭЛЕМЕНТАРНОЙ СЕРЫIn order to remove mercaptans and other sulfur containing compounds. compounds in the process of gas-phase heterogeneous catalytic purification of air, industrial gases as catalysts, proposed alumina, kaolin, oxides of alkaline earth metals, etc., carriers, on the surface of which are up to elemental sulfur
нанесена VOj или , с содержанием окислов урана от I-8О°ь 3J.deposited VOj or, with the content of uranium oxides from I-8O ° 3J.
В этом известном решении описываютс методика приготовле П1Я катализатора и провод тс примеры по очистке газовых смесей от органической серы.This known solution describes the procedure for preparing a P1H catalyst and provides examples on the purification of gas mixtures from organic sulfur.
Оптимальньгми услови ми работы катализатора окислени серусодержащих соединений вл ютс 4ОО С, объем на скорость газового потока 5 ОС чThe optimal operating conditions for the catalyst for the oxidation of sulfur-containing compounds are 4OO C, the volume per gas flow rate is 5 OC h
В результате окислени серусодер- жаших соединений образуетс сероводород , который затем абсорбируетс в абсорбере .As a result of oxidation of the sulfur-containing compounds, hydrogen sulfide is formed, which is then absorbed in the absorber.
Из данного сообщени следует , что окись алюмини использовалась, нар ду с другими веществами, в качестве но- сител , а катализатором вл лись окислы ванади и урана, нанесенные на поверхность одного из указанных носителей .It follows from this report that alumina was used, along with other substances, as a carrier, and the catalyst was vanadium and uranium oxides deposited on the surface of one of these carriers.
Кроме того, использование такого катализатора обусловл ет необходик ость подогрева, его до температуры .In addition, the use of such a catalyst makes it necessary to preheat it to a temperature.
