What is the effect of antioxidants on the catalysts in aviation fuel?
Thread Content
The antioxidant used for the hydroprocessing of jet fuel in our unit is added at the inlet of heat exchanger E203. When the product quality is unsatisfactory or for other reasons, it is necessary to stop adding this antioxidant and switch to a longer-cycle operation. The type of antioxidant used is T501; technicians say that it has an impact on the catalyst, but it is not clear what exactly that impact is. We hope someone can provide a detailed answer.
Yes! I have the same question: who knows the exact chemical composition of aviation fuel antioxidants, as well as the mechanism by which they provide antioxidant effects!
