Abstract

Zeolite Y was synthesized from Arobieye mined kaolin in Ota, Ogun state Nigeria through metakaolinization and zeolitization. The thermal activation of kaolin was achieved through the process of metakaolinization while zeolitization involved alkaline attack of thermally activated amorphous kaolin (metakaolin) and its transformation into Zeolite Y crystal. Silica/Alumina molar ratio of 5.84 of dealuminated metakaolin was synthesized under hydrothermal treatment with aqeous NaOH at atmospheric pressure after 7 days aging at room temperature, and hydrothermally crystallized at 100oC for 24 hours. Zeolite NaY with Si/Al molar ratio of 3.46 was achieved and then modified to its hydrogen form by ion exchange with NH4Cl. The molar ratio of Zeolite Y in hydrogen form is 3.22. The sample was characterized by Scanning Electron Microscope (SEM) which gives Zeolite Y Structure.
