Abstract

FIELD: gas purification. SUBSTANCE: invention relates to petroleum processing, chemical, heat and power, and other industries and may be used for sanitary thermocatalytic cleaning of low-pressure oxygen-containing gases from harmful impurities, e.g. off gases from oxidative regeneration of catalysts and adsorbents. Essence of invention consists in that, to prepare catalyst by way of covering non-porous carrier with catalytically active suspension including catalytically active component and binding component in the form of adhesive solution followed by drying and calcining catalytic covering, as adhesive component, saturated aqueous solution of alumino-chrome-phosphate binder is used with weight ratio of catalytically active component to aqueous adhesive solution being from 3:1 to 5:1 and proportion of binder components alumina/chromium oxide/phosphorus pentoxide being 1: (1-0.5): (2-4). EFFECT: increased life time of catalyst due to elevated mechanical strength, heat resistance, and catalytic activity with no environmental pollution when being prepared.

Изобретение относится к нефтеперерабатывающей, химической, теплоэнергетической и другим отраслям промышленности и может быть использовано для санитарной термокаталитической очистки низконапорных кислородсодержащих газов от вредных примесей, например, отходящих газов окислительной регенерации катализаторов и адсорбентов. Предлагаемое изобретение решает задачу увеличения срока службы катализатора за счет повышения механической прочности, термостабильности и каталитической активности при отсутствии загрязнения окружающей среды в процессе получения катализатора. Сущность изобретения заключается в том, что для получения катализатора очистки газа от органических веществ и оксида углерода путем покрытия непористого носителя каталитически активной суспензией, включающей каталитически активный компонент и вяжущий компонент в виде раствора адгезива, с последующей сушкой и прокалкой катализаторного покрытия в качестве вяжущего компонента используют насыщенный водный раствор алюмохромфосфатной связки при массовом соотношении каталитически активного компонента и водного вяжущего раствора связки 3 : 1 - 5 - 1 и соотношении компонентов вяжущего раствора Al2O3 : Cr2O3 : P2O5 равным 1 : 1 - 0,5: 2 - 4.The invention relates to the refining, chemical, heat power and other industries and can be used for sanitary thermocatalytic purification of low-pressure oxygen-containing gases from harmful impurities, for example, exhaust gases of oxidative regeneration of catalysts and adsorbents. The present invention solves the problem of increasing the life of the catalyst by increasing the mechanical strength, thermal stability and catalytic activity in the absence of environmental pollution in the process of obtaining the catalyst. The essence of the invention lies in the fact that to obtain a catalyst for gas purification from organic substances and carbon monoxide by coating a non-porous carrier with a catalytically active suspension comprising a catalytically active component and a binder component in the form of an adhesive solution, followed by drying and calcination of the catalyst coating as a binder component, saturated aqueous solution of aluminochromophosphate binder with a mass ratio of the catalytically active component and the aqueous binder solution of the binder 3: 1 - 5 - 1 and the component ratio of binder solution Al 2 O 3: Cr 2 O 3: P 2 O 5 is 1: 1 - 0.5: 2 - 4.
