摘要：
Zeolite catalysts are widely used in oil refining, petrochemical and environmental catalysis etc. With decades of development, the preparation of zeolite catalysts are relatively mature. However, traditional routes usually involve the production of ammonia-nitrogen wastewater and nitrogen exhaust gas, which also inevitably lead to high production cost. Therefore, it is rather important to design and develop new clean and efficient preparation technology to reduce the cost and satisfy the increasingly restricted environmental demand. From the aspects of efficiency, environmental protecting, and economy, the problems in the preparation of zeolite catalysts are discussed as well as the corresponding solving tragedies such as avoiding or replacing organic template, sodium ion, solvent and binder, and recycling useful components. An outlook regarding the development trend of clean and efficient preparation of zeolite catalysts is also presented, which suggests that fundamental research should be strengthened and combined with its industrialization. In addition, the integration of various green preparation techniques with the aim to achieve high catalytic performance are the most important key to realize the eventual high efficient, low cost routes for preparation of zeolite catalysts. © 2021, Chemical Industry Press Co., Ltd.
