Title: Improved octane measuring process and device
Inventor: MAGGARD STEVEN M
IPC: G01N21/35
Filed: 1990-07-20
Granted: 1994-03-25
Abstract: The near infrared absorbance of the methyne band measures octane (pump, RON, and MON) with excellent correlation and can be used for gasoline blending. The absorbance may be measured as the first, second, third, fourth or higher derivative or by other signal processing techniques. The signal can be used to control a multi-component gasoline blending system to produce a preset desired octane. Such continuous or frequent measurement of octane (research octane number, RON; motor octane number, MON; and pump octane number (research plus motor times 0.5)) permits constant or frequent optimization of gasoline blending to produce a target octane which is sufficient to meet motorists' needs, yet uses minimum amounts of the more expensive high octane blending stocks.
