Abstract

Nanocrystalline ZSM-5 can be used as catalysts or catalyst supports,and it has higher catalytic efficiency compared with micro-sized ZSM-5 zeolite because of its large specific surface area,so it attracted wide attention.This paper mainly discusses the hydrothermal synthesis of nanocrystalline ZSM-5.Aluminium nitrate,tetrapropyl ammonium hydroxide(TPAOH) and tetraethyl orthosilicate(TEOS) are used as main reactants and reaction conditions are studied such as Si/Al,dispersion medium(water,ethanol and butanol),reaction temperature and reaction time so as to probe how they affect the size and yield of product.The best reaction conditions are confirmed by experiments and ZSM-5 zeolite has a average size of 60nm and yield over 90% prepared with ethanol as dispersion medium at 100 for 48 hours.This study lays foundation for next-step preparation of the catalyst.
