Abstract
A system, method and computer program product are provided for calculating one or more indicative properties, e.g., one or more of the cetane number, octane number, pour point, cloud point and aniline point of oil fractions, from the density and Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) of a sample of an oil sample.
Claims17
A system for assigning an indicative property of to a fraction of an oil sample, based upon Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) data, the system comprising:
- a non-volatile memory device that stores calculation modules and data, the data including FT-ICR MS data indicative of intensities at corresponding mass-to-charge ratio of ions (m/z) derived from the oil sample;
- a processor coupled to the memory;
- a first calculation module that calculates the carbon numbers and double hood equivalents from the FT-ICR MS data;
- a second calculation module that calculates and assigns a FT-ICR MS index value a function of the FT-ICR MS peak intensity and carbon numbers;
- and
- a third calculation module that calculates and assigns the indicative property as a function of the FT-ICR MS index value and a density of the oil sample.
