The main use of zeolitic molecular sieves is in laundry detergents. In 2001, an estimated 1200 kilotons of zeolite A were produced for this purpose, which entails water softening. [2] 4A molecular sieves are widely used to dry laboratory solvents. [7]
[23] [24] In chemistry, zeolites are used as membranes to separate molecules (only molecules of certain sizes and shapes can pass through), and as traps for molecules so they can be analyzed. Research into and development of the many biochemical and biomedical applications of zeolites, particularly the naturally occurring species heulandite ...
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.
Pentasil-zeolites are defined by their structure type, and more specifically by their X-ray diffraction patterns. ZSM -5 is the trade name of a pentasil-zeolite. As early as 1967, Argauer and Landolt worked out parameters for the synthesis of pentasilzeolites, particularly those relating to the following molar ratios: OH − /SiO 2 = 0.07–10, SiO 2 /Al 2 O 3 = 5–100, H 2 O/SiO 2 = 1–240.

It operates at near-ambient temperature and significantly differs from the cryogenic distillation commonly used to separate gases. Selective adsorbent materials (e.g., zeolites, (aka molecular sieves), activated carbon, etc.) are used as trapping material, preferentially adsorbing the target gas species at high pressure. The process then swings ...
Mordenite from Italy. Synthetic Mordenite is used as a catalyst in the petrochemical industry for the acid-catalyzed isomerisation of alkanes and aromatics.; In New Zealand mordenite-bearing zeolitic tuff is dried and crushed to produce a variety of products including adsorbents for soaking up oil/chemical spills and animal wastes, animal feed supplements, water treatment, and sports turf and ...
Zeolites are micro-crystalline solids composed of tetrahedral AlO 4 and SiO 4 building blocks. These crystals are porous in nature with characteristic micropore channels, cavities. Zeolite is known as one class of molecular sieve because of their channel openings are often between 0.4 and 1.5 nanometers, just enough for the molecules to pass ...
Zeolite Y was a certain type of molecular sieve that could refine petroleum. Zeolite Y surpassed Zeolite X before it. When refining "crude oil", or petroleum, it must be separated into all of its different parts, or fractions. Gasoline is one of the many fractions that come from refining petroleum. Flanigen's zeolites are used as catalysts, or ...
