Y-sit
Usage
- for adsorptive desulfurization of hydrocarbons
- for adsorptive separation of the hydrocarbon mixtures alkane – alkene
- for adsorptive separation and production of pure components from the isomers mixture
- for adsorptive final purification processes
General characteristics
Y-sit is a synthetic Y type zeolite with pores size 0.9 nm. Molecular sieves are crystalline aluminosilicates of alkali metals or alkaline earth metals. They have a 3-D crystal lattice with tetrahedrons SiO4 and AlO4 as its basic components, arranged to create a regularly alternating cavities. Dimensions of intra-crystalline cavities and entering pores into cavities are characteristic for the individual types of molecular sieves. Molecular sites do not contain toxic components. Such type of molecular sieve shows a high adsorption capacity and thermal stability.
Y-sit is sodium aluminosilicate. Its chemical composition in dehydrated state expresses the formula Na2O. Al2O3 . 4,5 SiO2.
