Catalytic reforming is a chemical process used in the petroleum industry to convert low-quality naphtha into high-octane gasoline. This process involves heating the naphtha and passing it over a catalyst, typically made of platinum or rhenium, which helps rearrange the molecular structure of the hydrocarbons. The result is a more valuable fuel that improves engine performance. In addition to producing high-octane gasoline, catalytic reforming also generates byproducts like hydrogen gas, which can be used in other refining processes. This method is essential for meeting fuel standards and enhancing the efficiency of internal combustion engines.
