Dry points of sulfuric acid and isooctane
Thread Content
We use a sulfuric acid-based stepped reactor, and we have our own device for the cracking and regeneration of sulfuric acid. Does using this self-regenerated acid continuously have an impact on the dry point of isooctane? I would appreciate it if experts could give me some advice.
I hope everyone will discuss more; thank you!
It doesn’t seem to have much of an impact...
There will be an impact; improper operation of the regeneration unit can result in higher levels of elemental sulfur and other impurities in the regenerated acid compared to that purchased from outside, which has a negative effect on the reaction, increases acid consumption, and leads to a higher dry point of the product.
There is no impact; the acid purchased externally is now also converted and absorbed after high-temperature pyrolysis. As long as it is not turned into nicotinic acid, there will be no issues.
