Research on polar substance characterization and adsorption separation process of heavy oil

Abstract

The combustibility and fluidity is usually a major issue in heavy oil of power plant, which affects by asphaltene and insoluble matter due to the long-term storage. In this dissertation, the effects of asphaltene and insoluble matter characteristics on the heavy oil properties have been theoretically and experimentally studied using different methods. For the combustibility study, the asphaltene was precipitated and verified by X-ray diffraction energy and dispersive spectrum analysis. Also, the rotating disk electrode atomic emission spectrometry was carried out for fluidity study and then calorific value and ash content are calculated. The combustibility and fluidity of heavy oil were improved with the method of non-polar solvents and strong polar adsorption by removing asphaltene polar and insoluble substances. The experimental shows that calorific value is 9721Kcal/kg and viscosity is 14.7mm2/s.
