Description
technical field [0001] The invention relates to chemical equipment, in particular to a water-cooled methanol synthesis reactor. Background technique [0002] Methanol is an important chemical basic raw material and clean liquid fuel, widely used in organic synthesis, dyes, pesticides, medicine and other industries. Methanol synthesis is a reversible exothermic reaction, and the reaction temperature determines the equilibrium and reaction rate of the reaction system. As the reaction temperature increases, the reaction rate increases, but the equilibrium constant of the reaction decreases. For specific catalysts and operating environments, there is an optimal methanol synthesis reaction temperature range. The method of realizing the optimal reaction temperature is often adopted in the industry such as continuous heat exchange, multi-stage cooling, water heat transfer, etc., so that the temperature of the catalyst bed can be distributed along the optimal temperature as much a...
