I have a question for my colleagues: Does using diesel to heat the sulfuric acid production plant for 36 hours before starting up it have any impact on the catalyst, equipment, and the manufacturing process?

If the temperature increase is successful, it has little impact on the catalyst and the equipment. If this is done several times in a row, the catalyst will be affected, with greater impacts on the first and third layers. This post was last edited by in the blink of an eye on 2009-4-16 09:41]
I agree with what was said above; repeated temperature increases have a significant impact on the catalyst, as the catalyst is highly dependent on temperature, and this could lead to its denaturation
Over the past few years, due to poor market conditions, we have had to park the vehicle for long periods of time on many occasions, and we have also used diesel fuel several times; we haven’t noticed any negative effects! It’s estimated that there should be an impact, but it’s not noticeable.
It is recommended to use a preheater for heating, as this method has less impact on the catalyst due to the way heating is carried out; the catalyst comes into direct contact with dry air!
Using natural gas would have less of an impact than diesel, right?
Catalysts are very sensitive to temperature; avoid large fluctuations in temperature
