Al-pillared montmorillonite was synthesized from raw clay, mined at Sipovo, Srpska Republic (Bosnia and Herzegovina). Its textural properties and bleaching capacity were compared with some commercial adsorbents and filtration aid materials commonly used in domestic oil industry. The bleaching capacity of Al-pillared montmorillonite is lower than that of commercial Super Celite L748 (Johns Manville, USA) or Perfit PF-3 (Termika dd., Zrenjanin, Serbia&Montenegro), but somewhat is higher than the bleaching capacity of pure montmorillonite. The results sugest that the bleaching capacity of the investigated samples is primarly determined by average pore diameter and not by specific surface area.
