Natural Jarosite Bearing Rocks, Treatment with Acid and Bases and Structural Characterization

الملخص

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 .
