【 摘 要 】

Five types of Al-Fe pillared Iraqi clays have been selected depending on a natural clays regions (Anbar- Mosul- Basra- Baghdad- and Erbil) have been used in preparation it, and tested for catalytic wet air oxidation (CWAO) using phenol as target compound at different parameters (temperature, pressure, phenol loading, catalyst loading). The Al-Fe pillared of Anbar- Mosul -and Erbil clay showed a higher activity than Baghdad and Basra for phenol oxidation in Batch reactor. After 8 days continues test for activating AL-Fe PC in PBR, Deactivation appears on catalyst of Anbar in different temperature, but in Erbil with increase temperature, Mosul catalyst has higher activity than other catalyst. Mosul catalyst has higher stability than Erbil and Anbar in blocking of surface area, Leaching Fe was negligible, Fairly different values of apparent activation energy were obtained for this reaction with these five types of catalysts, suggesting that the prevailing pathway in air decomposition is different. From all above discussion, Mosul catalyst in considered the best catalyst.
