Abstract
1. Реактор синтеза аммиака, в котором синтез-газ, содержащий азот и водород, разделен на два или более основных потока, каждый из которых подается в механически изолированную реакционную зону, причем охлаждение реакционных зон осуществляется с помощью теплообменных трубок, находящихся в слое катализатора, а движение газа через слои катализатора и охлаждающего вещества через теплообменные трубки, расположенные в катализаторе, осуществляется преимущественно вертикально.2. Реактор по п. 1, в котором в каждой реакционной зоне могут присутствовать два или боле слоев катализатора.3. Реактор по п. 2, в котором по крайней мере один слой катализатора снабжен теплоотводящими трубками.4. Реактор по п. 1, в котором катализатор располагается внутри трубок, а охлаждающее вещество подается в межтрубное пространство.5. Способ реконструкции существующего аппарата с получением реактора, описанного в пп. 1-4.1. An ammonia synthesis reactor in which the synthesis gas containing nitrogen and hydrogen is divided into two or more main streams, each of which is supplied to a mechanically isolated reaction zone, and the reaction zones are cooled using heat transfer tubes located in the catalyst layer, and the movement of gas through the layers of the catalyst and the coolant through the heat exchange tubes located in the catalyst is carried out mainly vertically. 2. The reactor according to claim 1, wherein in each reaction zone two or more catalyst layers may be present. The reactor of claim 2, wherein at least one catalyst bed is provided with heat sink tubes. The reactor according to claim 1, in which the catalyst is located inside the tubes, and the coolant is fed into the annulus. A method of reconstructing an existing apparatus to obtain the reactor described in paragraphs. 1-4.
