ABSTRACT:
Analysis of hydrocarbon mixtures to determine desired characteristics, particularly a determination of octane number of gasolines, undergoing partial oxidation/cool flame reactions. Pre-analysis performed on a target fuel sample of known composition and octane number is utilized to arrive at an optimum point of the reaction, a point believed to represent a condition where a maximum of the fuel is oxidized during the reaction. In the preferred embodiment disclosed, the optimum point is the reactor block temperature that generates a maximum peak temperature rise of the cool flame reaction of the target fuel. This optimum reactor temperature is utilized in further analyses of other known samples to develop a matrix of peak temperature rise versus time to reach peak coordinates. Any unknown fuel sample whose peak amplitude/time coordinate is within the matrix is compared with matrix values to determine its octane number as well as an indication of its composition. The overall arrangement is embodied in a microprocessor controlled octane analyzer suitably interconnected with a refinery process stream to provide continuous on-line octane number monitoring.
