What role does oxygen play in the degradation of stored fuel?

Oxygen is a significant factor in the degradation of stored fuel because it accelerates oxidation, a chemical process that results in the breakdown of fuel components. When fuel is exposed to oxygen over time, it undergoes various chemical reactions that can lead to the formation of harmful byproducts, such as gums and varnishes, which can cause clogging in fuel systems and reduce the overall quality and performance of the fuel.

In the presence of oxygen, hydrocarbons in the fuel react to form new compounds, which can lead to the deterioration of the fuel's properties. For instance, the increased oxidation can result in the development of acidity in the fuel, promoting further degradation and potentially leading to corrosion of storage tanks and fuel lines.

This understanding is crucial for effective fuel management and storage practices, as minimizing oxygen exposure can help preserve fuel quality and extend its usable life.
