Hierarchical H-ZSM5 Zeolites synthesized from Iranian natural Kaolin clay for Methanol to Hydrocarbon conversion

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.
