The present study involved the processing of raw Ukpor clay from Anambra State, Nigeria to kaolin as a precursor for the development of Y-type zeolite. The clay was first subjected to pretreatment by separating the foreign bodies from it using deflocculant (Sodium hexametaphosphate and Sodium hydrogen carbonate). Subsequently, the pretreated clay was calcined at 850°C for 6 hours at atmospheric pressure. The calcined clay was formulated by adding sodium hydroxide and sodium metasilicate to produce a gel aged at room temperature for 12 hours. The gel was subsequently heated in a laboratory oven at 100°C for 9hrs to produce the Y-type zeolite in a process called crystallization and a product with Si/Al molar ratio of 4.07 was achieved which is suiting for a typical Zeolite Y. The formulated samples were characterized using X-ray Fluorescence (XRF), Fourier Transform Infrared Spectroscopy (FTIR), and Scanning Electron Microscope (SEM). The results showed possible synthesis of Y-type zeolite from Ukpor kaolinite having a molar ratio of 15Na2O:Al2O3:15SiO2:450H2O. The synthesized product with Si/Al ratio of 4.07, an agglomerated euhedral morphology, and FTIR spectra peak at wavelengths of 719cm-1 and 3424cm-1, are the basis upon which the conclusion of possible development of Y-type zeolite is drawn.
