What is the effect of pressure on methanol synthesis?

The methanol reaction is a reaction with a decrease in the number of molecules, and increasing pressure is favorable for the forward reaction. If the pressure increases, the partial pressure of the components rises, and thus the production intensity of the catalyst also increases. For the operation of the synthesis tower, pressure control is adjusted accordingly based on the different catalytic activities at various stages of catalyst use; when the catalyst is new and has high activity, the operating pressure can be kept lower ； As the catalyst ages, its activity declines, and higher operating pressures are often employed to maintain a certain level of production intensity. In summary, the selection of operating pressure must be determined based on specific factors such as catalyst activity, gas composition, reactor thermal balance, and system energy consumption
