Oxidation Process

Definition

The oxidation process is a chemical reaction that involves the transfer of electrons from one substance to another, typically resulting in an increase in the oxidation state of the reacting substance. In the context of hydrogen and ammonia as fuel sources, this process plays a crucial role in energy release and combustion efficiency. Understanding how oxidation works is essential for optimizing fuel performance and reducing emissions in combustion technologies.
