Doping of ninivite silica gel with selenato and oxalato chromium complex, structural and physical properties and their application in petroleum refining

الملخص EN

This study concerns with the doping of Ninivite silica gel by selenato and oxalate chromium complex in ratio of 1 : 1 for the two complexes and studying their physical and structural properties.

Results of x-ray powder diffraction, x-ray fluorescence, thermal analysis, infrared spectra and technical instrumental analysis evaluated the scientific and economic utilization of those samples as adsorbents to separate Qaiyarah heavy crude oil Petrolene into four simple components according to their polarities.

Infrared spectroscopy has been applied to study the chemical the chemical composition of the separated fractions.
