Reduction of methanol synthesis catalyst
Thread Content
Why must the temperature-raising reduction process of methanol using catalysts follow the principle of \"raising temperature without increasing hydrogen pressure, and increasing hydrogen pressure without raising temperature\"?
Both heating and hydrogen addition can accelerate the reduction reaction rate. Adhering to the principle of \"increasing temperature without increasing hydrogen, and increasing hydrogen without increasing temperature\" is intended to better control the rate of the reduction reaction, keep the active lattice of the catalyst as small as possible, thereby achieving the greatest active surface area and optimal activity.
Controlling the heating rate to prevent overheating is highly beneficial for the reduction catalyst, as it results in good activity after reduction
Since both increasing hydrogen flow and raising temperature will cause the bed temperature to rise, in order to ensure complete and thorough reduction, the temperature should be increased gradually and systematically; these two control methods should not be used simultaneously to avoid excessive temperature rises.
Both heating and hydrogen addition can accelerate the reduction reaction rate, which in turn leads to an increase in temperature and may damage the catalyst crystals
