Chromatographic and mass-spectrometric study of individual composition of catalytically reformed naphthas
By means of a method of Chromatography/mass spectrometry, a study has been made of the individual composition of a straight-run naphtha and a catalytically reformed naphtha (IBP-180°C). Individual compositions have been determined for the feedstock and for the products issuing from each of the reactors of the unit.
Feasibility has been demonstrated for detailed study of the chemical conversions of hydrocarbons that take place in the naphtha reforming process, on the basis of results of chromatographic/mass-spectrometric analysis of the naphtha feed and the products obtained at various stages in the reforming.
A procedure has been proposed for the Chromatographie analysis of catalytically reformed naphthas (IBP-180°C) in capillary columns, using a preliminary mass-spectrometric identification of the Chromatographic peaks, the obtained relative retention volumes, and the order of hydrocarbon exit.
