Abstract

Highly dispersed materials Fe3O4@TEOS and Fe3O4@PVP for asphaltenes extraction from organic media have been synthesized via modifications of nanosized magnetite with tetraethoxysilane and N-polyvinylpyrrolidone. Using model compounds simulating the main functional groups of asphaltenes and some natural asphaltenes isolated from crude oil, the sorption capacity was estimated for Fe3O4@TEOS. It was found that the extraction degree of asphaltenes from a toluene solution at 45°C reached 65–70%, and the sorption capacity was 28mgg–1.
