STUDY THE PHYSICAL PROPERTIES OF SUDAN NATURAL AND SYNTHETIC ZEOLITES MODIFICATION BY PT ELEMENT.

Zeolites is one of very important elements that for several application in various technologies . Zeolite material, dependance on their extremely high frame work ,extended interactive surface , ability to interact with molecules and cations . Show a wide variety of interesting properties which result in remarkable applications in the fields of catalysts, gas separation, selective adsorption and water softening. The natural zeolites are materials with their properties ( that in some cases are even unique ) or super than those obtained by synthetic . The zeolite catalyst loaded with finely dispersed noble metal (Pt) have been used in hydrogenation, hydrocracking, hydroiosmerization and the oxidation of hydrocarbons . In this study the natural zeolite collected from north of Sudan and prepared it to determination the physical properties . And the other one is Synthetic zeolites (Y) . The natural zeolite (scolecite) and synthetic zeolite (Y) are modification by two methods impregnation and ion exchange using ammonium chloride and platinum hydrochloride H2PtCl6 to upgrade their properties . The study characterized the natural zeolite ( Scolecite ) and Synthetic zeolites Y and their modification using different techniques as follow : Thermal analysis by two methods DSC , TGA ,TPR and measured surface area of zeolite Y by BET . The result show good characterization of two types of zeolites specially after modification with Pt element and it be ready to use in application.
