Abstract
Internal combustion engine liquid fuels 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 light-weight hydrocarbons comprising one- to four-carbon components. The light-weight hydrocarbons, which preferably constitute less than 3 percent of the blended fuel, can be recovered to generate power to run the process. The liquid fuel 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.
Claims13
A process for producing liquid fuels for internal combustion engines, comprising the steps of withdrawing a stream of light-weight hydrocarbons from a natural gasoline component, and blending said natural gasoline component with at least one octane-enhancing component, said octane-enhancing component having an (R+M)/2 octane of at least about 85 and a vapor pressure less than about 8 psia.
A process for producing liquid fuel for internal combustion engines, comprising the steps of:
- a) blending liquid components comprising a natural gasoline component and at least one octane-enhancing component;
- b) producing a high-surface area form of said liquid components of step a) in an enclosure having a vapor space portion and a liquid space portion, said liquid components collecting in said liquid space portion of said enclosure, vapors accumulating in said vapor space portion of said enclosure, a vapor stream being withdrawn from said vapor space portion of said enclosure;
- c) a liquid removal step in which low-weight hydrocarbons present in said vapor stream are removed and returned to said blending step a), said liquid removal step further producing a light-weight hydrocarbon vapor product;
- d) said light-weight hydrocarbon vapor product of said liquid removal step c) being burned to generate power, said power being utilized to provide energy for said process;
- and,
- e) said process continuing until said liquid components have a composition of between about between about 60 and about 80 volume percent natural gasoline, and between about 20 and about 40 volume percent octane-enhancing components.
A process for producing a liquid fuel for internal combustion engines, comprising the steps of:
- a) blending liquid components comprising a natural gasoline component and an octane-enhancing component;
- and,
- b) withdrawing a vapor stream of light-weight hydrocarbons from said liquid components, whereby the vapor pressure of the resulting blended liquid product will be decreased.
