Natural Mineral Clays Bearing Bentonite , Grafting by Chromium Tri Oxide Studies and Application In Petroleum Fraction

الملخص

Natural Iraqi mineral clays treated chemically by base using sodium hydroxide and
grafting with chromium trioxide by using thermal analysis, infrared ,ultraviolet and high
performance liquid chromatography .Result indicate that this sample have physical and
structural properties evaluated their scientific and economic utilization to be applied in
fraction processes as adsorbent to separate Iraqi heavy crude oils into their simple component
