Description

При получении окислов азота в большом масштабе путем каталитического окислени  аммиака, выход их часто уменьшаетс , несмотр  на то, что газова  смесь предварительно нагрета до надлежаш,ей температуры . Это наблюдаетс  в случае применени  контактных масс в виде сло , особенно при употреблении железа или других неблагородных металлов или их окислов в форме кусков. Это  вление, по мнению изобретател , объ сн етс  тем, что тепло передаетс  от поверхности внутренним сло м контактной массы, вследствие чего происходит слишком сильное охлаждение тех частей контакта, на которые раньше всего действует газовый поток.When producing nitrogen oxides on a large scale by catalytic oxidation of ammonia, their output often decreases, despite the fact that the gas mixture is preheated to the proper temperature. This is observed when using contact masses in the form of a layer, especially when using iron or other non-precious metals or their oxides in the form of lumps. This phenomenon, according to the inventor, is due to the fact that heat is transferred from the surface to the inner layers of the contact mass, as a result of which there is too much cooling of those parts of the contact that are primarily affected by the gas flow.

Предлагаемый способ имеет цельюThe proposed method is intended

устранить эти недостатки путем устройства достаточно большой реакционной камеры перед контактом , дл  того чтобы теплота, излучаема  раскаленным контактом, вызвала дальнейшее нагревание до 500° и выше газовой смеси, поступаюш ,ей в камеру после предварительного нагревани  до температуры около 400°.eliminate these drawbacks by arranging a sufficiently large reaction chamber before contact, so that the heat radiated by the hot contact causes further heating to 500 ° and higher gas mixture flowing into the chamber after preheating to about 400 °.

На практике можно осуществить это так: предварительно нагретый до 400° газ ввод т в верхнюю часть широкой и длинной вертикально поставленной камеры, в нижней части которой находитс  контактна  масса, расположенна  в форме слоев. Контактной массы газ достигает с температурой около 550°.In practice, this can be done in the following way: preheated to 400 ° C gas is introduced into the upper part of a wide and long vertically placed chamber, in the lower part of which there is a contact mass located in the form of layers. The contact mass of the gas reaches a temperature of about 550 °.
