Sieving
II.B.1 Sieving. Sieving is one of the oldest methods of analysis, but the particle size measured is ill defined. Sieves are made from woven wire, from plates with holes punched in them, or by electroforming holes in a plate. A quantity of the powder is placed on top of the sieve, which is usually vibrated so that the smaller particles fall ...

MOLECULAR SIEVES
Synthetic zeolite X has larger pores (7.8 Å) and can accept e.g. SF 6, C 6 H 5, naphthalene. The mechanism of molecular sieving is a complex interaction to which zeolite structure, cation content and Si/Al composition all contribute. Permeation of gases through zeolites is a diffusion process so temperature controls gas separations.

Excellent gas separation performance of hybrid carbon
However, the use of 10X zeolite with a pore size of 0.8 nm is not effective for molecular sieving due to the diameters of the interesting gas pairs are in the range of 2.89 to 3.84 Å. Interestingly, we observed that the selectivity for H 2 /N 2 and H 2 /CH 4 also increases with higher zeolite content.
