The synthesis of hierarchical zeolites using two kinds of molecular sieve is discussed,especially the methods of post-processing and templating. The degree of desilication or dealumination,and suitable but cheap templates are essential techniques to develop hierarchical zeolite materials.

针对ZSM-5和SAPO-34两种不同的分子筛体系,介绍了多级孔道沸石制备的后处理法与模板法,指出控制后处理脱硅脱铝的程度以及探寻合适且廉价的模板剂是发展多级孔道材料的关键技术。

. And all the optimum conditions are obtained. (3)Flowsheet structure study for desilication by reverse floatation: including Stage Grinding and Stage Separation, Individual Middling Regrinding and Re-Flotation, and Intensifying Secondary Concentration Technology, etc.

通过工艺矿物学研究和大量的条件试验、流程结构试验研究，找到了贵州铝土矿反浮选脱硅的最佳条件。
