Zeolite Y and its Derivatives (NaY, USY, ReY) – Used in the Catalysts of FCC And RFCC Units (Behda NY, Behda UY, Behda RY)
Application:
Zeolite Y is the main catalyst component used in FCC/RFCC refinery units. The selectivity and catalytic activity of these types of catalysts are due to zeolite Y. Although this zeolite has other applications such as dehumidification, its mainly used in the world as the main catalyst component of the FCC/RFCC residue fluid catalytic cracking process.
Product Introduction:
Zeolites are generally minerals that are mainly composed of aluminosilicates with a regular crystalline structure, and they are commercially used in various industries as surface adsorbents. Among natural zeolites, only 9 types such as clinoptiolite, natrolite and stilbite are found in nature, and a large number of them are synthesized artificially and through chemical reactions. The structure of zeolite Y has a three-dimensional pore system in which the pores of 3.7 angstroms connect larger cages (with a diameter of 13 angstroms) to one another, which are known as supercages in this zeolite.
Technical Specifications:
In the process cycle, first this product is prepared using silicate and aluminate sources. Due to the semi-stable nature of zeolite Y, its manufacturing steps must be carefully controlled, otherwise the final product will be another material and will not be used. Usually, solutions containing sodium hydroxide (caustic soda) are used for the synthesis of zeolites. Sodium in soda as a positive ion neutralizes and balances the tetrahedral negative charge of aluminum. This zeolite is called soda Y or NaY. Common sources of silica and alumina are sodium silicate and sodium aluminate, respectively. Crystallization of zeolite Y usually takes place within
35 hours at 100°C. Production of a high quality zeolite requires precise control of temperature, time and pH of the crystallization solution. NaY zeolite is separated from the crystallization solution after filtration and washing with water. NaY zeolite is not hydrothermally stable due to its high sodium content. The size of the particles, the size and volume of the holes and the active surface area of the product are its important features.

Application:
Among the applications of these compounds are the removal of oil and gas sulfur compounds such as mercaptans and H2S (which is essential in the process of refining crude oil and gas) as well as air pollutants such as CO and CO2. Another important application of these zeolites is the use in washing powders as an agent for absorbing calcium ions from water.
