Industrial desiccants - Import export

These crystals are characterised by a three-dimensional pore system, with pores of precisely defined diameter. This diameter is in the dimension of the size of molecules such as water, CO2 and H2S. The pores can be adjusted to precisely determined uniform openings allowing for molecules smaller than its pore diameter to be adsorbed whilst excluding larger molecules, hence the name “molecular sieve”. The different pore sizes of synthetic zeolites open up a wide range of possibilities in terms of "sieving" molecules of different size or shape from gases and liquids.
