<p>Blended gasolines are produced by the mixing of a natural gasoline component and at least one octane-enhancing component. The mix is weathered during the blending operation to remove lightweight hydrocarbons comprising one- to four-carbon components. The lightweight 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 burnt in an internal combustion engine, produces a minimum amount of pollutants.</p> |
