Abstract
The use of Moroccan oil shale for the preparation of adsorbents by
chemical activation with phosphoric acid is analysed. The results indicate
that this material is promising for this application. The effect of
different conditions of preparation on the yield and surface area is
discussed. These parameters are H3PO4/shale weight ratio,
carbonisation temperature, carbonisation time and concentration of
H3PO4.
