General description. Molecular sieves are synthetically produced zeolites (naturally occurring aluminosilicate minerals), and are characterized by pores and internal cavities of extremely uniform dimensions. These crystalline materials have three-dimensional structures based on silicon oxide (SiO 4) and aluminum oxide (AlO 4) polyhedra.

The molecular sieve adsorbent is utilized immediately before a cryogenic process to remove water so that ice is not created during the process. However, inherent in the process is the fact that the hydrocarbon feed stream contains unsaturated hydrocarbons, such as alkenes, which are very reactive. These unsaturated hydrocarbons tend to form ...
Zeolite 3A, which can act as a molecular sieve toward water, has been implemented in the drying of olefins, thus avoiding possible oligomerization inside the pores of the adsorbent. This molecular sieving effect has proven practical, as well, for drying mixtures which contain other polar compounds, such as alcohols or even the ethanol/water ...
process, the solid is called the adsorbent and the solute is known as the adsorbate. Commercial adsorbents are highly porous, with pore sur-face areas ranging from about 100 to 1,200 m2/g. The large surface area allows a large amount of adsorption relative to the weight of the adsorbent, well in excess of its own weight in some cases.
Regeneration can be carried out as often as required. Our molecular sieves with 0.3 nm bead form and with moisture indicator brown gel can be used in Karl Fischer titrators. MilliporeSigma molecular sieves are suitable for drying practically all gases and liquids and feature high adsorption capacity even at high temperatures.

In general, the higher the silica-alumina ratio of the molecular sieve, the less acidic the molecular sieve, the more HC adsorption [28], the better the thermal and chemical stability of the molecular sieve. For some special adsorbent materials, changing the Si/Al ratio will also affect the selective adsorption of different HC species.

A molecular sieve, also called a mole sieve, is a type of drying agent that can absorb certain, specific materials. It is made of a porous, crystalline material. The pores, measured in angstroms, are a uniform size similar in size to small molecules. That means larger molecules cannot enter through the material or be absorbed but the smaller ...
