Claims (4)

1. Способ селективного каталитического окисления сероводорода в серу, включающий пропускание исходного газа, содержащего хотя бы сероводород и кислород, через неподвижный слой гранулированного катализатора, содержащего оксид железа на пористом оксидном носителе, отличающийся тем, что используют катализатор в виде гранул, имеющих форму либо цилиндра, либо кольца, либо сферы, либо любой объемной фигуры, с эквивалентным диаметром не менее 5 мм, при этом в качестве носителя используют материал, характеризующийся величиной эффективного коэффициента диффузии кислорода в условиях реакции в диапазоне 4·10-6-1,4·10-5 м2/с.1. A method for the selective catalytic oxidation of hydrogen sulfide to sulfur, comprising passing a source gas containing at least hydrogen sulfide and oxygen through a fixed bed of a granular catalyst containing iron oxide on a porous oxide support, characterized in that the catalyst is used in the form of granules having the form of either a cylinder , or rings, or spheres, or any volumetric figure, with an equivalent diameter of at least 5 mm, while using a material characterized by the value of the effective coefficient itsienta diffusion of oxygen under reaction conditions in the range of 4 · 10 -6 -1.4 · 10 -5 m 2 / s. 2. Способ по п.1, отличающийся тем, что в качестве исходного газа используют смешанные с воздухом или кислородом отходящие газы установок Клауса.2. The method according to claim 1, characterized in that the exhaust gas mixed with air or oxygen from Claus plants is used as the source gas. 3. Способ по п.2, отличающийся тем, что отходящие газы установок Клауса перед смешением с воздухом или кислородом, подвергают гидрированию с превращением диоксида серы и всех прочих сернистых примесей в сероводород.3. The method according to claim 2, characterized in that the exhaust gases of the Claus plants before being mixed with air or oxygen, are subjected to hydrogenation with the conversion of sulfur dioxide and all other sulfur impurities to hydrogen sulfide. 4. Способ по п.2, отличающийся тем, что минимизацию концентрации диоксида серы в отходящих газах установок Клауса обеспечивают за счет снижения подачи воздуха в печь Клауса до уровня ниже стехиометрической величины.4. The method according to claim 2, characterized in that the minimization of the concentration of sulfur dioxide in the exhaust gases of Claus plants is achieved by reducing the air supply to the Claus furnace to a level below the stoichiometric value.
