Service life of methanol catalyst
Thread Content
The methanol catalyst used in my company has been in use for less than a year; the catalysts from several different manufacturers have given similar results, and the specific factors affecting this are unknown! It is understood that similar situations exist among some domestic manufacturers as well; some of them increase the amount of catalyst used in order to extend its service life. Although this approach yields some results, it increases production costs and does not resolve the underlying problem. I wonder if there are any other friends who produce methanol in similar situations; what’s your experience like?
The typical service life of a catalyst is 3 years, so there should be no problem. With proper control, it can last for over 4 years. I don’t know what catalyst you’re using
It takes a year – are the catalysts you use domestic?
It must be a problem with the indicators and operations! The catalysts themselves, when operating under normal load, last for about three years!
Generally it’s three years, with a maximum of 5 years in our case.
1. Operations during startup and shutdown. 2. Key parameters for gas analysis. 3. Check whether there are any issues with the equipment. 4. Check for any problems during loading
What type of synthesis tower does your factory use? Catalyst model? Raw material route? Perhaps I can offer some help
We use Topsoe’s process equipment; the catalysts used in the early stages were from Topsoe, but later domestic catalysts were adopted. However, these catalysts have been changed several times, with each replacement lasting no more than 1 year. Our company is involved in the production of methanol from coal; we hope to hear good news. Thank you! Please
The reactor is from Topsoe; how much catalyst is loaded? What is the actual airspeed? Theoretically, there are four main categories of reasons for catalyst deactivation. Check the operation records to see if there were any instances of excessive temperature or unexpected shutdowns that led to carbon deposition/toxification of the catalyst. The most likely coal types are prone to poisoning or causing the sintering catalyst to overheat during operation; catalyst samples can be taken for analysis when shutting down the system. Our company manufactures, sells, and develops methanol catalysts; we are also the designated authority for standard monitoring of methanol catalysts, and can assist with sample collection and analysis.

Do you have a sulfur protector in your synthesis? What is the purification process?
