13X Molecular Sieve

Silica Gel Directs Molecular sieves are a synthetically manufactured version of Zeolite and feature an intricate network of pores and empty cavities, giving it exceptional adsorbing properties. However, it is the smaller molecules that have a high absorption capacity. Molecular sieve has the fastest absorption rate among desiccants.

13X Molecular Sieve has a pore size of roughly 10A. This is considerably larger than any of the A type openings. This desiccant is used primarily for refinements of liquid and gases because it offers synchronised absorption for bi-molecule and tri-molecule, can be used as a desiccant for medical and compressor uses and as a catalyze carrier, air plantfeed purification (simultaneous H2O and CO2 removal) and liquid hydrocarbon/natural gas sweetening (H2S and mercaptan removal).

All molecules which can be adsorbed on Molecular Sieve types 3A, 4A, and 5A can be adsorbed on type 13X.

It has become one of the most reliable desiccants for a variety of applications including:

Storage and Shelf Life: Supplied in an active state, the product must be commissioned imediately to maximise lifespan, as water in the air around an open canister will be rapidly adsorbed, exhausting the media.

Product shelf-life from date of production is only 12 months in original pacakaging, which are opened by us to dispense the product, we will ensure that the product reaches you with at least 10 months of shelf life left. Store the molecular sieve in a cool location and at bellow <90% humidity.

Product life once commissioned is 3-5 years, unless exhausted by saturation first. It is possible to regenerate Zeolite by baking in an oven at 300c, at which point the moisture level will be reduced to approximately 2%. Then the product most be cooled in a desiccator, this is extremely energy intensive and is most often discarded, and replaced with a fresh Molecular Sieve.
