Claims (4)

1. Способ каталитического получения аммиака, включающий стадии пропускания потока синтез-газа, содержащего азот и водород, через три слоя катализатора, расположенных один поверх другого, которые содержат катализатор на основе железа с магнетитом как главной составной частью, который восстанавливают в течение процесса до каталитически активной формы альфа-железа, получения указанного потока синтез-газа объединением потока, который подают непосредственно в первый слой катализатора, с другим потоком, который предварительно подогревают непрямым теплообменом с продуктами, покидающими первый и второй слои катализатора, и выделения конечного продукта, отличающийся тем, что перерабатываемый газ пропускают через средний слой катализатора при объемной скорости от 0,65 до 2,00 от объемной скорости, с которой перерабатываемый газ пропускают через верхний слой катализатора.1. A method for the catalytic production of ammonia, comprising the steps of passing a stream of synthesis gas containing nitrogen and hydrogen through three catalyst beds arranged on top of each other that contain an iron-based catalyst with magnetite as the main component, which is reduced to catalytically during the process active form of alpha iron, obtaining the specified stream of synthesis gas by combining the stream, which is fed directly to the first catalyst bed, with another stream, which is preheated on indirect heat exchange with products leaving the first and second catalyst layers and the release of the final product, characterized in that the processed gas is passed through the middle catalyst bed at a space velocity of 0.65 to 2.00 from the space velocity at which the processed gas is passed through the upper catalyst bed. 2. Способ по п. 1, отличающийся тем, что реакцию проводят при объемном отношении между средним слоем катализатора и верхним слоем катализатора между 0,5 и 1,5. 2. The method according to p. 1, characterized in that the reaction is carried out at a volume ratio between the middle catalyst layer and the upper catalyst layer between 0.5 and 1.5. 3. Реактор для каталитического получения аммиака, содержащий три слоя катализатора, расположенных один поверх другого, первый теплообменник, расположенный между выходом из верхнего слоя катализатора и входом в средний слой катализатора, второй теплообменник, расположенный между выходом из среднего слоя катализатора и входом в нижний слой катализатора, первую линию для подачи исходного синтез-газа, содержащего водород и азот, присоединенную непосредственно к входу в верхний слой катализатора, вторую линию для подачи исходного синтез-газа и последующего пропускания его через первый и второй теплообменники, которая присоединена к первой линии, и линию для удаления конечного продукта, присоединенную к выходу из нижнего слоя катализатора, отличающийся тем, что линия для удаления конечного продукта присоединена непосредственно к выходу из нижнего слоя катализатора. 3. A reactor for the catalytic production of ammonia, containing three catalyst layers located one on top of the other, a first heat exchanger located between the outlet from the upper catalyst layer and the entrance to the middle catalyst layer, a second heat exchanger located between the exit from the middle catalyst layer and the entrance to the lower layer catalyst, a first line for supplying the initial synthesis gas containing hydrogen and nitrogen, attached directly to the entrance to the upper catalyst layer, a second line for supplying the initial synthesis gas and followed by passing it through the first and second heat exchangers, which is connected to the first line, and a line for removing the final product, connected to the outlet of the lower catalyst layer, characterized in that the line for removing the final product is connected directly to the outlet of the lower catalyst layer. 4. Реактор по п. 1, отличающийся тем, что объемное отношение между средним слоем катализатора и верхним слоем катализатора составляет между 0,5 и 1,5. 4. The reactor according to claim 1, characterized in that the volume ratio between the middle catalyst layer and the upper catalyst layer is between 0.5 and 1.5.
