C5+ refers to a hydrocarbon mixture obtained from the refining of crude oil or natural gas, composed of molecules containing five or more carbon atoms—such as pentanes, hexanes, heptanes, and heavier hydrocarbons. These compounds generally exhibit higher boiling points and serve as valuable intermediates in various refining and chemical processes.
C5+ fractions are commonly utilized as feedstocks in the production of gasoline, industrial solvents, and a wide range of petrochemicals. Their composition and final application depend on both the origin of the feedstock and the specific refining technologies used. Due to their versatility and energy-rich nature, C5+ streams are integral to both fuel production and the broader petrochemical industry.
