Highly Characterized Reference Standard: Heavy Straight Run Naphtha

A straight run naphtha, or gasoline, is produced from crude oil by distillation, typically in the temperature range of 60-320°F. Light straight run naphtha is the distillate fraction collected at 60-170°F; heavy straight run naphtha typically is collected at 170-320°F. Heavy straight run naphtha is a hydrotreating or reforming base (feed) stock. Straight run naphthas usually have low octane numbers. This application note demonstrates the preparation of a "real world" reference standard for the evaluation of refinery process performance and identification of sources of contamination.
