AbstractPreparation and characterization of an adsorbent catalyst from natural mineral clay sample obtained from Kara Tappa area in the province of Diyala/ Iraq, in addition to its application in petroleum industries have been studied.
The solubility of the clay sample in some acidic and basic mediums was performed in order to get the more active and selective adsorbent catalyst, as a result, the sample which was treated progressively by three (25%) concentration acids (HCL, H2SO4 and CH3COOH) was the best from the adsorbent view. Physical properties as well as chemical analysis of these samples were investigated. The mineralogical properties of those samples, powder x-ray diffraction, x-ray fluorescence, thermal analysis and infrared spectra.
Results indicated that such materials bear montmorillonite mineral in their composition in addition to others which vacillate them to be an adsorbent catalysts applied in chromatographic fractionation of Qaiyarah petrolene using five eluants increased in their polaritie. Infrared, nuclear magnetic resonanc (1H&13C NMR) techniques were utilized to determine the chemical composition of the separated fractions
