| Abstract | ||
| Abstract Jarosite-bearing rocks , which deposit in our country in a modest quantities , have been treated with different concentrations of acids and bases to obtain a natural adsorbent materials applied in fractionation processes . Jarosite adsorbents which have been obtained via the treatment of 25% hydrochloric acid show the best developing catalyst in activity and selectivity efficiency . Physical properties, chemical analysis, thermal analysis, infrared spectroscopy, x-ray diffraction and fluorescence were performed to characterized the jarosite samples . The results indicate the possibility of using them in fractionation processes . They have been used to fractionate Qaiyarah heavy crude oils into their sub-fractions . | ||
