Description
Изобретение относитс к области приготовлени катализаторов дл окислени сернистого ангидрида.The invention relates to the field of the preparation of catalysts for the oxidation of sulfur dioxide.
Известен способ получени катализатора дл данного процесса путем смешени носител с активным компонентом,содержапщм окись кали и п тиокись ванади ,с последуюищм формированием катажзаторной массы, сушкой и прокаливанием.A known method for producing a catalyst for this process is by mixing the carrier with the active component, containing potassium oxide and vanadium pentoxide, followed by forming a sedimentation mass, drying and calcining.
Катализатор,полученный по известному способу,обладает высокой активностью, однако после длительной работы при температуре выше 6QOPC существенно тер ет свою активность за счет изменени структуры носитегт л и молекул рного состава активного компонента. Креме того,в известном способе возникают некоторое трудности при формировании катализаторной массы.The catalyst obtained by a known method has a high activity; however, after long-term operation at temperatures above 6QOPC, it significantly loses its activity due to a change in the structure of the carrier and the molecular composition of the active component. In addition, in the known method, there are some difficulties in the formation of the catalyst mass.
Цель изобретени - увеличить термостабильность катализатора и улучшить тиксотропные свойства катализаторной массы.The purpose of the invention is to increase the thermal stability of the catalyst and improve the thixotropic properties of the catalyst mass.
Это достигаетс путем пре|дварительной обработки носител щдратихюванной ц тиокисью ванади содержащей 0,5-3f, VzOsZ поверхностно активным веществом,например 5 ,вз тым в количестве 2-10 вес.This is achieved by preliminarily treating the carrier with a generic vanadium thioxide containing 0.5-3f, VzOsZ with a surfactant, for example 5, taken in an amount of 2-10% by weight.

0 смепшвают с гидратированнои п тиокисью ванади ,вводимой в виде суспензии или образущейс в результате нейтрализации серной кислотой раствора ванадата щелочного металла,добавл емого к носителю. При замешивании добавл ют также ПАВ.0 is mixed with hydrated vanadium pentoxide, administered as a suspension or resulting from the neutralization with sulfuric acid of an alkali metal vanadate solution added to the support. When mixing is also added surfactant.
В результате одновременного введени пщратированной п тиокиси ванади и ПАВ,например , получают массу с высокими тиксотропными свойствами вследствие образовани из кристаллов п тиокиси ванада пространственной сетки,внутри которои находитс кремнеземистый носитель . Полученную массу формуют на любом форйующем устройстве,в томAs a result of the simultaneous introduction of vanadium pentoxide and ground-washed pentoxide, for example, a mass with high thixotropic properties is obtained due to the formation of a spatial grid of vanadium pentoxide crystals, within which there is a silica carrier. The resulting mass is molded on any fording device, including
