What is zeolite Y used for?
Zeolite Y is essentially used as a Fluid Cracking Catalyst (FCC) of heavy petroleum distillates, for increasing the yield of gasoline and Diesel fuel from crude oil (Kung at al. 2000).
What is the function of ZSM 5?
ZSM-5 has been used as a support material for catalysis. In one such example, copper is deposited on the zeolite and a stream of ethanol is passed through at temperatures of 240 to 320 °C as a vapour stream, which causes the ethanol to oxidize to acetaldehyde; two hydrogens are lost by the ethanol as hydrogen gas.
What is FAU type zeolite?
Faujasite (FAU, LiLSX) zeolites are commonly used for emission control in industrial off-gas purification. As process catalysts, they are suitable for fuel upgrading and air liquefaction.
What is mordenite zeolite?
Mordenite is one of the most abundant zeolites in altered volcanic deposits; it is found in volcanic rock such as rhyolite, andesite, and basalt. It is associated with other zeolites such as stilbite and heulandite. Good examples have been found in Iceland, India, Italy, Oregon, Washington, and Idaho.
How do you synthesis ZSM-5?
Synthesis of ZSM-5 Zeolite ZSM-5 zeolite with a SiO2/Al2O3 ratio of about 80 was synthesized by a hydrothermal method. In a typical run, mixture A was made by adding tetraethyl orthosilicate (TEOS) into the NaOH aqueous solution; the solution was stirred overnight at ambient temperature for the hydrogenolysis of TEOS.
What is Pentasil family?
The PerBU in the pentasil family, the pentasil layer (Fig. 1(left)), is composed of T12-units (bold in Fig. 1). T12-units, related by a rotation of 180º about c accompanied by a translation of ½c, form left- and right-handed chains along c.
What is clinoptilolite used for?
Use. Clinoptilolite has many applications due to its effect as a molecular sieve, among others as an additive for building materials, as aggregate in horticulture, as an additive to cattle feed, as an additive in household products, as a desiccant, and in environmental technology.
