What is the term for the process of blending different fuels?

The term "fuel formulation" refers to the process of blending different fuels to achieve specific properties, such as performance, emissions, and compatibility with engines. This process is critical in the petroleum industry because different fuels can have various characteristics, and blending helps satisfy regulatory standards and consumer needs.

In fuel formulation, various base fuels and additives are mixed in precise proportions to create a final product that meets established specifications for volatility, energy content, and environmental impact. This process ensures that the resulting fuel provides optimal performance in engines, minimizes emissions, and adheres to safety protocols.

Other options, while related to fuel processes, do not accurately describe the blending of different fuels. "Fuel combination" is a more general term that could imply various methods without the specific application of creating a formulated fuel product. "Fuel synthesis" typically refers to the chemical processes used to produce fuels from raw materials or other chemicals rather than the blending of existing fuels. "Fuel refining" pertains to transforming crude oil into usable products through processes such as distillation and cracking, rather than the blending of fuels. Thus, fuel formulation is the precise term that captures the essence of combining different fuels effectively.
