Doping of Ninivite Silica Gel with Selenato and Oxalato Chromium Complex, Structural and physical properties and their application in petroleum refining

Abstract

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.
