Description

Известны способы получени  окислов азота каталитическим окис-леиием аммиака кислородом в контактных трубках с отводом тепла реакции от катализатора вод ным паром, воздухом или другим теплоносителем посредством непосредственного контакта последнего с катализатором . Однако при этих способах содержание окислов азота в отход щих газах невелико.Known methods for producing nitrogen oxides by catalytic oxidation of ammonia with oxygen in contact tubes with heat removal of the reaction from the catalyst with steam, air, or other coolant through direct contact of the latter with the catalyst. However, with these methods, the content of nitrogen oxides in the exhaust gases is small.

Предлага:емый способ получени  окислов азота отличаетс  тем, что процесс ведут так, что одна сторона контактных трубок служит только катализатором, а друга  сторона находитс  в контакте с теплоносителем . Способ позволит повысить содержание окислов азота в отход щих газах.The proposed: method for producing nitrogen oxides is characterized in that the process is carried out in such a way that one side of the contact tubes serves only as a catalyst, and the other side is in contact with the coolant. The method will allow increasing the content of nitrogen oxides in waste gases.

Контактные трубки должны быть выполнены из металла,  вл ющегос  катализатором дл  окислени  аммиака, например из платины и ее сплавов.Contact tubes should be made of metal, which is a catalyst for the oxidation of ammonia, such as platinum and its alloys.

В качестве теплоносител  примен ют воду, воду-пар, ртуть и другие жидкости. Пар может быть получен за счет тепла реакции.Water, water-steam, mercury and other liquids are used as heat-transfer agents. Steam can be obtained by the heat of reaction.

Дл  осуществлени  способа может быть использован контактный аппарат типа теплообменника или парового котла, в трубках которого, сделанных из контактного материала, происходит процесс окислени  .аммиака.For carrying out the process, a contact apparatus such as a heat exchanger or a steam boiler can be used, in tubes of which are made of contact material, an ammonia is oxidized.

На чертеже изображен такой аппарат, имеющий контактные трубки /, проходы 2 дл  теплоносител , вход и выход газовых смесей 3. В таком аппарате можно вести процесс получени  окиси азота контакт .ным окислением аммиака кислородом, содержащим от 12 до 40Vo (объемных) аммиака.The drawing shows such an apparatus having contact tubes /, passages 2 for heat carrier, inlet and outlet of gas mixtures 3. In such apparatus, one can carry out the process of producing nitric oxide by contact oxidation of ammonia with oxygen containing from 12 to 40Vo (volume) ammonia.
