Description

Изобретение относитс  к катализаторам дл  окислени  сероводорода из газов и может найти применение в процессах очистки от сероводорода природных газов, газов нефтепереработки, Тадсже хвостовых газов процесса Клауса.This invention relates to catalysts for the oxidation of hydrogen sulphide from gases and may be used in the processes for the purification of hydrogen sulphide from natural gases, refinery gases, Tadjer tail gases from the Claus process.

Известен катализатор.дл  газофазного окислени  сероводорода содержащий оксиды титана и железа при следующем содержании компонентов, мас.%: оксид железа 0,05-0,3, диок-. сид титана - остальное.Known catalyst. For gas-phase oxidation of hydrogen sulfide containing oxides of titanium and iron with the following content of components, wt.%: Iron oxide 0.05-0.3, diox. titanium sit - the rest.

Катализатор, содержащий 0,1 мас.% оксида железа и 99,9 мас.% диоксида титана  вл етс  наиболее зффектив- нь1м и обеспечивает максимальную конверсию сероводорода 99,5% и селективность 100% при переработке больших кличеств сероводорода до 25%. Однако высока  активность катализатора такого состава может быть достигнута лишь при двухстадийном окислении сероводорода с раздельной подачей кислорода на каждую стадию и улав- ливанием образующейс  серы и воды на промежуточной стадии. Производительность титан-железооксидного катализатора невысока, ибо«он про вл ет высокую активность лищь при низких объемных скорост х подачи сырь  не выше 3000 ч , увеличение объемной скорости до 15000 приводит к значительному снижению активности катализатора. Вместе с тем эффективна  эксплуатаци  катализатора возможна лишь при повьшенных темпе- ратурах 285-300°С.A catalyst containing 0.1 wt.% Iron oxide and 99.9 wt.% Titanium dioxide is the most effective and provides a maximum hydrogen sulfide conversion of 99.5% and a selectivity of 100% when processing large amounts of hydrogen sulfide up to 25%. However, a high activity of a catalyst of such a composition can be achieved only by two-stage oxidation of hydrogen sulfide with a separate supply of oxygen to each stage and the trapping of the sulfur and water formed at the intermediate stage. The performance of the titanium-iron oxide catalyst is low, since it exhibits a high lisch activity at low volumetric feed rates of not more than 3000 hours, an increase in the space velocity to 15,000 leads to a significant decrease in catalyst activity. At the same time, efficient operation of the catalyst is possible only at elevated temperatures of 285-300 ° C.

Наиболее близким к предлагаемому по технической сущности и достигае- мому эффекту  вл етс  катализатор дл  очистки газов, содержащих соединени  серы, например сероводород, сероуглерод, меркаптан, двуокись серы, путем их окислени , содержа- щий носитель - диоксид титана, или циркони , или кремни , или цеолит и один или несколько оксидов следующих металлов: Си, Ag, Zn, Cd, V, Za Cr, Mo, W, Fe, Co, Ni, Rh, Jr, Pd, Pt, Sn, Bi, при этом общее коли-, чество одного или нескольких металлов на носителе составл ет 0,005- :25 мас.%.Closest to the proposed technical essence and the achieved effect is a catalyst for cleaning gases containing sulfur compounds, for example hydrogen sulfide, carbon disulfide, mercaptan, sulfur dioxide, by oxidizing them, containing a carrier — titanium dioxide or zirconium, or silicon , or a zeolite and one or more oxides of the following metals: Cu, Ag, Zn, Cd, V, Za Cr, Mo, W, Fe, Co, Ni, Rh, Jr, Pd, Pt, Sn, Bi, with the total -, the content of one or several metals on the support is 0.005%: 25% by weight.

Однако дл  известного катализатора характерна недостаточна  активность . Так, при окислении сероводорода при 240 с и V 6000 ч вHowever, a known catalyst is characterized by insufficient activity. Thus, in the oxidation of hydrogen sulfide at 240 s and V 6000 h in
