Why does diesel turn darker in color and become cloudy after pickling?
This is caused by the gums present in diesel, and it is also a factor that affects the stability of diesel.
If it is catalytic diesel, it contains a high level of olefins; without hydrogenation, these olefins oxidize in the air, causing the color to darken
Is it that certain substances undergo dehydration or condensation during pickling to form long-chain substances?
Because the diesel components have become heavier, with a high gel content
The darkening color is due to the high content of olefins in diesel, which results in poor oxidation stability and the formation of gums upon contact with oxygen.
There’s no good solution; it’s mainly a problem with the raw materials and the reaction. Besides, catalyzed diesel is generally released after hydrogenation, so it has no significant impact
Regarding the agreement on the fourth floor’s statement, is there any connection between panhun and sulfur-nitrogen?! Please give some advice!:P
Try adding 10% No. 200 and then pickling
