Review on Hierarchical Zeolite Beta from Kaolin: Synthesis Methods and Applications

Abstract

In order to overcome mass, diffusional transfer limitations and molecular accessibility in microporous zeolites, several researches have been carried out towards the synthesis of hierarchical Zeolite Beta catalysts comprising of micro/meso/macropores structures mainly using chemical reagent which are mostly hard to get and at times expensive . This review is focused on seeing the extent of research that have being done on the synthesis of hierarchical zeolite Beta from kaolin. Different synthetic methods and strategies of making Zeolite Beta as it relate to using readily available sources such as kaolin was discoursed and the catalytic application in various applications was highlighted .
