Kerosene smoke point issue
Thread Content
How to adjust and improve the smoke point of aviation fuel?
Increase the hydrogen partial pressure and raise the hydrogen-to-oil ratio
The smoke point reflects the aromatic content; a low smoke point indicates a higher level of aromatics in the raw material, as well as insufficient hydrogenation
Hydrogenation is insufficient; is it refining or cracking hydrogenation? Increasing the temperature should help with hydrogenation, right?
Raising the temperature helps to accelerate the reaction rate of aromatic saturation, but the equilibrium constant for aromatic saturation decreases. Simple purification does not have a significant effect on aromatic saturation, and it has little impact on increasing the smoke point; modification yields better results. It is necessary to consider the performance of the catalyst, as well as other factors such as higher pressure and the hydrogen-to-oil ratio
