Abstract

A process and apparatus for preparation of custom blended fuels is disclosed. A bar code on a fuel tank or vehicle, such as an automobile, is scanned by a bar code reader operatively associated with a fuel dispensing means to convey information about a fuel required or desired to a computer controlled customized blender associated with the fuel dispensing means. Multiple fuel components, such as gasoline and replenishable fuel components such as methanol and ethanol may be custom mixed at the point of purchase. Preferably an octane analyzer and other fuel property analyzers, such as RVP analyzers, are associated with individual component or blended gasoline streams.

  • 3. The present invention relates to the analysis and blending of motor vehicle fuels.
  • 4. II. Description of the Prior Art
  • 5. The problem of tailoring motor vehicle fuels, especially gasoline octane, to the needs of various consumer vehicles has long been apparent. Solutions have included providing a number of different gasoline pumps at a single retail outlet so that the consumer may select the pump which dispenses the fuel best suited to a vehicle's requirements and blending pumps which blend a high octane component such as alkylate with a low octane gasoline according to an octane dialed into the dispensing pump. Recently, this situation has been complicated by mandated gasoline formulations as dictated by Congress and various states, and by different tax treatments granted to ethanol, methanol, and other replenishable fuel components in different states. Also, legislation in specifying maximum Reid vapor pressure (RVP) in various locals has become popular and must be balanced against the need for some minimum RVP in order to ensure starting of the motor vehicle in cold weather and cold climates. Taken altogether these motorist demands and government regulations can best be satisfied by blending gasoline from more than two components and by blending as close to the point of sale as possible.

  • 8. In another embodiment, the present invention provides a process for blending and dispensing a customized fuel to a vehicle in response to a bar code on the vehicle comprising maintaining multiple fuel component storage means connective with individual conduit means and metering means, reading a bar code on said vehicle and using one or more computer means, receiving inputs from said bar code reader, to determine the fuel requirements of said vehicle, blending a fuel for said vehicle by mixing in a mixing means connective with said fuel component storage means to produce a blended fuel, dispensing said customized fuel into said vehicle, displaying at least one of cost, volume, or properties of said customized Fuel dispensed to said vehicle in response to said bar code on said vehicle.
  • 9. In preferred embodiments, two, preferably three or more gasoline 9or other fuel) blending components are delivered to a point adjacent to the point of sale to the motorist and are blended by an apparatus which proportions the flow of individual components in response to signals indicative of the gasoline quality variables, octane, Reid vapor pressure, percent alcohol, etc. The preferred octane for control purposes is motor octane, but pump octane or research octane or any combination of these three may be utilized. Analysis of octane is preferably performed by near-infrared spectroscopy, more preferably NIR operating in the t-butyl/methyne band, and most preferably through a signal which comprises the second derivative of the absorbance in that particular band. Preferred methods of control are proportioning pumps operating in response to an octane or other variable, optional additional input by the consumer, and periodically or continuously reset according to feedback received from the octane measured in the blended fuel. Reid vapor pressure and other gasoline variables are controlled similarly. Setting of the variable speed proportioning pumps in response to information input by the vehicle via bar-code reading, input by the consumer, processing of the NIR absorbance signal, and other quality control-indicative signals for feedback to the proportioning pumps, pricing and calculation of total cost are all well within the state of the art of computer technology.
