The soaking process after the catalyst has been reduced
Thread Content
After the methanol catalyst is reduced, there is a hydrogen immersion process, with a hydrogen content of 20 to 30 percent. Why is there such a process?
High-hydrogen immersion is used to fully reduce the catalyst; however, the hydrogen concentration used for high-hydrogen reduction of catalysts in China is generally not that high, while only foreign catalysts require such high hydrogen concentrations for reduction.
After the methanol catalyst is reduced, there is a hydrogen immersion process aimed at ensuring complete reduction of the catalyst so that it can be reused; otherwise, the catalyst would suffer excessive wear and damage.
For those that are not reduced with pure hydrogen, it’s impossible to do it
Soaking is mainly used to ensure complete reaction of the catalyst; you should be using a catalyst from Johnson Matthey. Domestic catalysts generally serve both to raise the temperature and to produce hydrogen
