Description

technical field

[0001] The invention is a catalytic reaction equipment, which is used for fluid catalytic reaction and heat transfer process, belongs to the field of chemical engineering, and is especially suitable for synthesizing methanol, synthesizing dimethyl ether, Fischer-Tropsch reaction to produce liquid hydrocarbons and methane, o-xylene oxidation to produce ortho Strong reaction processes such as phthalic anhydride. Background technique

[0002] For some strong exothermic reactions such as methanol synthesis, synthesis gas to dimethyl ether, Fischer-Tropsch reaction to liquid hydrocarbons and methane, o-xylene oxidation to phthalic anhydride, etc., in order to improve the reaction efficiency, it is necessary to remove the reaction heat at the same time. , For example, the Lurgi shell-and-tube methanol tower uses shell-side water to remove the heat of reaction in the reaction tube. In the shell-and-tube reactor design, the temperature of the coolant does not change ...
