What is the goal of the isomerization process?

The goal of the isomerization process is to enhance the quality of petroleum products, specifically by increasing the octane rating of fuels. This process involves rearranging the molecular structure of hydrocarbons to create isomers that have higher octane numbers. A higher octane rating is important as it allows for more efficient combustion in engines, reduces engine knocking, and improves overall engine performance.

While the production of lower emission fuels can be a secondary benefit of isomerization due to improved combustion properties, the primary aim of this process focuses on enhancing the fuel's octane rating, making it a more critical aspect of isomerization.
