Abstract
Zeolites play a crucial role as chemical materials in various chemical processes, with their production typically involving the use of costly chemicals. In this research work, Ibeno clay was utilized as the precursor material for the synthesis of zeolite Y. Zeolite Y was synthesized for the first time using Ibeno kaolin. The successful production of Zeolite Y followed a specific process: raw kaolin clay was collected from the Ibeno area of Akwa Ibom state, Nigeria, and then underwent processes including beneficiation, calcination, partial dealumination, gelation, and final hydrothermal synthesis. To beneficiate the raw clay, a sedimentation technique was employed, resulting in the recovery of 97 percent kaolin while a substantial amount of quartz and other impurities were removed. Innovative metakaolinization techniques were applied to transform the kaolin into a reactive metastable phase, yielding amorphous metakaolin at a temperature of 850°C with a residence time of 4 hours. The alumina content in the metakaolin was subsequently reduced by reacting it with sulfuric acid over nine days, achieving a Silica/Alumina molar ratio of 5. The distinctive process of gel formation and crystallization leading to NaY zeolite was successfully carried out within 24 hours at a temperature of 100°C. The synthesized zeolite NaY was characterized using XRF and XRD and the result obtained shows Zeolite NaY with 96% purity. The socio-economic benefits include catalysis in petroleum refining, environmental remediation, detergent formulation, catalytic cracking in biofuel production, ion exchange applications, etc.  ...
