How long is the service life of high-pressure alcohols in the alcohol alkylation process?
Thread Content
Currently, people are discussing the alcohol alkylation process – how long is the service life of high/medium pressure alcohol catalysts?
Reply to 2# yg20080707: Which manufacturers have been using it for five years? We’ve only used it for about three years; we can learn from them*.
I agree with the opinion from the second floor; apart from gas purification reasons, it is also related to the CO and CO2 levels at the inlet of the alcoholization system, as well as the level of operational skill； The typical service life is 3-5 years.
It’s been about two and a half years now; the temperature for medium-alcohol is around 260 degrees, and that for high-alcohol is around 255 degrees. However, the hot spot is now at bed four.
Here, we use high-pressure alcohol catalysts for 5 years
What process comes before high-pressure alcohol? What is the purity level? Both sulfur and ammonia can affect high-pressure alcohol catalysts.
High-pressure alcohol: the temperature at the hot spot has reached 260 already; it’s only been two years since the fourth layer was used
