Molecular dynamic simulations were conducted to study the crystallization process of ZSM-5 zeolite from engineering perspective.The influence of temperature on radial distributions of oxygen of water were calculated,and the results indicated that the formation process of ZSM-5 zeolite might be divided into two stages,precursor formation and nucleation stage at a low temperature and crystal growth stage at a higher temperature.At a higher temperature,homogenous nucleation was suppressed,therefore,the best nu...
