The Effect of Ultrasonic Irradiation on Preparation Zeolite Catalyst from Natural Mineral

Abstract

The objective of the research is to study ultrasonic radiation in preparation of zeolite catalyst. Natural zeolite that obtained from Gunung Kidul District Indonesia was contain components like SiO2, Al2O3, CaO, MgO, Na2O,K2O that potency decelop as catalyst. This material used for synthesis of zeolite catalyst with dealumination, neutralization, drying and calcination processes. In dealumination process did with ultrasonic assisted with time variation 1-6 hours. The zeolite catalyst was analyzed X-ray Diffraction and specific surface area. The results shown crystal percentage decreased due ultrasonic radiation and type of zeolite change complex type to sillicalite. The surface area of zeolite catalyst increased with ultrasonic radiation.
