BLENDED GASOLINES Blended gasolines are produced by the mixing of a butane-pentane rich component, a natural gasoline component, and a toluene component. The mix is weathered during the blending operation to remove light-weight hydrocarbons comprising two, three and four-carbon components. The light-weight hydrocarbons, which preferably constitute less than 3 percent of the blended gasoline, can be recovered to generate power to run the process. The liquid gasoline mixture is formulated to produce a desired octane rating, an environmentally acceptable vapor pressure, and a mix which, when burned in an internal combustion engine, produces a minimum amount of pollutants.
