Trends in Properties of Unleaded Gasolines.
Abstract
During the years 1973 and 1974, 72 samples of unleaded gasoline were obtained from refineries and service stations representing a broad spectrum of petroleum companies and locations across the continental United States. These samples were analyzed for properties normally associated with gasoline specifications and for more detailed hydrocarbon composition. Compared to average properties of conventionally leaded regular grade gasolines, the average unleaded fuels were found to contain higher concentrations of aromatic hydrocarbons equivalent olefin content and lower octane values. Compared to 1971 and 1972 unleaded fuels, these products showed little variation in hydrocarbon type composition, and sulfur content; however, lead content, even as a contaminant, was found to be at minimum levels while organo-phosphorus additives were not present in smaples analyzed in 1974.
