Precautions for water removal during catalytic temperature rise reduction of methanol
Thread Content
The catalyst has a short service life of 4-5 months. Seek advice on precautions for temperature increase and reduction to remove water using methanol as a catalyst
When performing heating reduction, make sure to drain all the water from the outlet drain. There are no other drainage precautions. There are many reasons why the catalyst has a short lifespan!
The amount of water released during the catalytic heating reduction process reflects the intensity of the reduction reaction. This amount of water should be strictly controlled in accordance with the manufacturer’s instructions; the release of water should not be too sudden. A steady flow of water indicates that the reduction reaction is proceeding smoothly, that the temperature is easy to control, and that the reduction effect is good. During the temperature-raising reduction process, the following principles must be strictly followed: three lows – low-temperature water discharge, low-hydrogen reduction, and a period of low-load operation after reduction. Three stabilities: stable temperature rise, stable hydrogen supply, and stable water output. Three prohibitions: Temperature increase and hydrogen addition must not be carried out simultaneously ； Moisture must not be introduced into the synthesis tower ； Do not allow water to flow at high temperature for a long time. Three controls: Control the H2 supplementation rate ； Control CO2 concentration ； Control the water outlet speed. Furthermore, if there is a lack of experience in heating and reduction processes, it is advisable to have the technical staff from the catalyst manufacturer involved throughout to provide guidance, so that any issues can be addressed promptly!

The amount of water produced during the catalytic heating and reduction process reflects the intensity of the reduction reaction. It is primarily necessary to control the temperature rise of the methanol synthesis catalyst; if the temperature rises too much, an excessive amount of hydrogen will be combined with the catalyst. Even if the temperature of the methanol synthesis catalyst does not exceed its limit, such a high temperature rise can still reduce the pore size of the catalyst, thereby affecting its lifespan
