Study On Synthesis And Application Of NaY Zeolite

This thesis is divided into two parts, the first part of the synthesis of NaY zeolite.Y-zeolite and new synthesized inorganic porous materials in recent years have beenapplied in many fields including catalysis,adsorption, ion-exchange and so on. Comparedwith conventional particle size of zeolite, nano-zeolite shows many unique features, suchas: a larger surface area, more active center and the outer surface of short and regular porestructure. As the petrochemical industry, increasing demand for molecular sieves, how todirect, rapid and efficient synthesis of small size, high specific Surface area of the NaYzeolite, it is particularly important.In this work, the effects of Si/Al ratio of directing agent, the aging time of nucleation,and the crystallization time were investigated in the single–factor experiment andorthogonal analysis. Results show the optimum conditions. The nano-zeolites werecharacterized by means of scan electron micrography （SEM） and powder X-ray diffraction（XRD）. Finally, we make a economic evaluation about the modified activated carbon onits process of CO₂capture. The results show that the process of the project is mature andentirely feasible, and it has dual economic and social gains at the same time.
