Quantitative analysis of multicomponent mixtures of petroleum products by a combination of NMR spectroscopy and mass spectrometry

A combination of mass spectrometry and nuclear magnetic resonance spectroscopy was used to monitor the process of manufacture of liquid fuels with a high density and a high specific calorific value from the by-products of pyrolysis of crude oil fractions. This methodology provided information that characterizes the component, fragment, and group composition of samples for all stages of this process and facilitated the development of ideas on the genetic relation of components of heavy oil residues.
