چكيده فارسي :
Hierarchical zeolites have some synthetic advantages of high stability and selectivity due to possessing both micro and meso pores. particularly, Various structure-directing agents has been explored for construction of hierarchical ZSM-5 structures. Herein, Hierarchical zeolites have been synthesized from Iranian natural kaolin clay as a low-cost silica and aluminum resource due to some synthetic advantages of high stability and selectivity. particularly, the steam assisted conversion with a low cost and green affordable monosaccharide structure-directing agents has been explored for direct construction of hierarchical HZSM-5 structures. The relation between precursor molar ratio and zeolites crystallinity, Acidity and porosity was studied for zeolites that was prepared with different Si/Al ratio.
