Abstract

The invention discloses a fixed bed catalytic reactor, mainly comprising a shell 1, an upper seal head 2 and a lower seal head 3, wherein the shell 1 is connected with the upper seal head 2 and the lower seal head 3, the upper seal head 2 is provided with a steam outlet pipe 5, the lower seal head 3 is provided with an air inlet pipe 6 and an air outlet pipe 7, the shell 1 is provided with a water inlet pipe 8 or the lower seal head 3 is provided with the water inlet pipe 9, and a heat-exchange external pipe 10 internally containing a catalyst is connected with an upper pipe sheet 11 or a lower pipe sheet 12. The fixed bed catalytic reactor is used in processes for synthesizing methanol, hydrocarbons and the like, can also be used in processes for synthesizing methane, methyl ether and the like, and has the advantages of large production capacity, high catalyst activity, simple and reliable structure and good operating performance.

Description

technical field [0001] The invention is a catalytic reaction device, which is used for fluid catalytic reaction and heat transfer process, belongs to the field of chemical engineering, and is especially suitable for synthetic reaction processes of methanol and hydrocarbons, and can also be used for synthetic processes of methane and methyl ether. Background technique [0002] For exothermic catalytic reactions such as synthesis of methanol, methyl ether, and hydrocarbons under pressure, the temperature of the catalyst layer is raised by the continuously released heat of reaction as the reaction progresses. In order to increase the efficiency of the reactor, it is necessary to remove the reaction heat to lower the reaction temperature. It has been widely used in industrial reactors, such as the shell-and-tube reactor for methanol synthesis of Lurgi Company in West Germany. The raw material gas enters and distributes into each tube from the upper gas inlet, and methanol is syn...
