Study on the Potential of Kaolinitic Clay from Perak State, Malaysia for Aluminosilicate Ceramic Ball

Abstract:

Commercially made kaolin is identified as one of the important materials for production of aluminosilicate for catalyst bed support. In this work, an attempt is made to study the potential of local clay for production of aluminosilicate. Three area were identified as kaolin sources in Perak state as they are Trong, Simpang Pulai and Bidor, and labelled as TC, SP and BC, respectively. For preparation of aluminosilicate, formulation using 30% clay and the rest used feldspar (40%) and silica sand (30%). Each batch were formed into ball shapes’ before fired at 1250°C at controlled firing rate of 3°C/min. From the investigation, it is found that only two local clays (CBTC and CBSP) highly potential to be used to produce ceramic ball for catalyst support. In addition, the crushing strength is 100% better than the commercial made product which also have less than 1% water absorption.
