The zeolite membrane is a new type inorganic membrane and can achieve molecular sieving,which is an important part of the membrane separation technology. The zeolite membrane has effect on concentration,purification,separation and reaction promotion,which is an desirable separation and catalyst membrane materials for the low energy consumption in the separation process. With the development of industry,the purification and the separation conditions of products in the processes of the chemical reactions become more and more complicated,which have the demand of well acid-resistant and corrosion-resistant zeolite membrane. Therefore,the preparation of the acid-resistant and corrosion-resistant zeolite membrane is needs further improvement,which can enhance the industrial application of the membrane separation technology. The study is mainly on introducing the preparation,application status and the industrial development prospect of the acid-stable zeolite membrane.
