Natural jarosite bearing rocks, treatment with acid and bases and structural characterization

الملخص EN

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.
