Utilization of Nagarparker kaolin for the synthesis of zeolite-zsm, a value added product

Abstract

Nagarparker arid zone of Pakistan. It has large deposits of Kaolin (China Clay) approximately 4.3 million tons. Crystal zeolite ZSM produced and characterized. Material ground, calcined dehydrated using ball mill, autoclave and furnace respectively due to dehydration kaolinite converted into metakaolin with a weight loss of about 3.9% and 8 M solution of Sodium hydroxide added with the ratio of 1:5 at 100 °C with vigorous stirring for 1 h. Fusion carried out at 100 °C for 1 h, sample washed 3 times to make its pH normal. Characteristic Si-O-Al, OH, Al-OH and Si-OH bands were confirmed in Fourier Transform Infrared Spectroscopy studies. Scanning Electron microscopy showed clear morphology of zeolite zsm. Xray Diffraction showed 2ÆŸ peaks and revealed orthogonal shaped crystal structure. The results show that the Nagarparker kaoling is suitable for the synthesis of Zeolite ZSM as value added Product.
