Letter to the Editor: Improving the Stability of Diesel Fuel from Heavy Oil Catalytic Cracking

Diesel fuel has the potential to form sediment during storage as a result of fuel instability. The cause is due to the presence of unstable components such as unsaturated hydrocarbon compounds and non-hydrocarbon compound. Other effects such as light, oxygen, temperature, and the catalytic action of metals also play a role. In order to improve the stability of diesel, we have studied the potential for stabilizers to mitigate the formation of the precipitate. Experimental results show that stabilizers can effectively decrease the content of unstable components in diesel fuel, and improve the stability of storing, and have a beneficial effect on the stability of the fuel.
