Zeolites occur naturally, however some have been synthesized over the years. Zeolites are the aluminosilicate members of the family of microporous solids known as molecular sieves. Zeolites are widely used as ion-exchange beds in domestic and commercial water purification, softening, and other applications.

Nov 11, 2020 · Zeolites are considered a cornerstone of the modern petroleum and chemical industries, because their human-made synthesis and industrial applications have greatly helped drive the revolutions in petroleum refining and chemical production processes.

Zeolites are three-dimensional, microporous, crystalline solids with well-defined structures that contain aluminium, silicon, and oxygen in their regular framework; cations and water are located in the pores. The silicon and aluminium atoms are tetrahedrally coordinated with each other through shared oxygen atoms.

An analysis of gas chromatography pulse dispersion data for the system n‐butane/zeolite NaY is presented.The data were analyzed in terms of two models, an intracrystalline diffusion limiting model and a surface barrier model. Aug 19, 2019 · Ultrastable Y (USY) zeolite is an effective catalyst used for catalytic cracking in petroleum refining. This catalyst is prepared from ammonium Y zeolite by steaming at high temperatures above 773 K. From this process, aluminum cations are dislodged from the framework of the Y zeolite. NaY Zeolite, a kind of alkali silicon aluminate, is Y­type crystal sodium zeolite. It can adsorb molecules whose critical diameters are no greater than 10 angstrom. It is used for catalytic cracking catalysts preparation, drying dehydration, hydrogen desulfurization, the catalysts support, the purification of gases of oil refining and chemical industry, metallurgy, electronics and nuclear related industries.

The zeolite NaY catalysts had higher surface areas and greater stability upon impregnation and calcination than the RHS catalysts, which collapsed after catalyst preparation. Hence, the NaY-supported catalysts were more active than the RHS-supported ones.
