Why does the newly produced diesel change color so quickly? What antioxidants are needed? What are the different types of antioxidants available?
I also know what stabilizer is suitable to add?
The diesel produced by new catalytic units tends to change color, mainly due to high levels of nitrogen oxides and gum-like asphaltenes. Solutions include: 1. Hydrogenating the incoming diesel. 2. Add diesel stabilizer. 3. Add a decolorizing agent. We have used an imported diesel stabilizer that proves to be quite effective; it is added at the inlet of the diesel pump, causes no losses or sediment formation, allows the diesel to remain stable for a month with little change in color, and its cost is 10–20 yuan per ton. Another option is to add a decolorizing agent; the loss is 2–3%, alkali slag needs to be removed, the shelf life is about 7 days, and the cost is approximately 20–30 yuan per ton. I won’t mention which manufacturer’s products it is here, to avoid any suspicion of advertising; if you need it, send me a message!
It’s not clear whether you’re referring to catalyzed diesel – just a color change, or whether its oxidation stability is satisfactory. Adding diesel stabilizer can solve the problem.
Our diesel hasn’t had anything added to it.
Diesel contains nitrogen oxides and gum-like asphaltenes, which readily react with oxygen, causing the diesel to turn black. By adding diesel oxidizers, such reactions between these substances in diesel and oxygen are prevented, thus resolving the issue of darkening color in diesel. However, it is merely a diesel refining method that provides only temporary relief; the diesel treated in this way remains colorless for about a month. To truly improve the quality of the product, hydrogenation is necessary
Yes! Adding D21 diesel multi-functional stabilizer will effectively extend the storage period by 30-40 days, preventing oxidation and discoloration
I would like to ask everyone: I want to learn more about this, so please give me some advice! Thank you!
That one has diesel antioxidants and antidegradants!
Zhejiang Hongmai Technology: D21 diesel antioxidant stabilizer, D71 diesel pour point depressant
Our company has diesel refining fluid, which fits your needs quite well!
Diesel refining fluid is used to address oxidation and discoloration in diesel caused by residual acids and alkalis; it is not as effective for issues arising from other reasons during the refining process. Additionally, the refining fluid requires time to settle so that the oils can be separated
Try Hongmai Technology’s D21 diesel multi-functional stabilizer – it improves the oxidative stability of diesel, prevents oil oxidation, and extends the existing color retention for 2-3 months
It is mainly nitrides, which cause oxidation and lead to discoloration
For diesel produced from different raw materials, pilot tests are required to determine which antioxidant is most effective
