It is a molecular sieve with a distinctive lattice structure that allows only a certain size range of hydrocarbon molecules to enter the lattice.
42.
Once the beads are full of water, temperature or pressure can be manipulated, allowing the water to be released from the molecular sieve beads.
43.
These adsorbents ( e . g ., zeolites ) form a molecular sieve and preferentially adsorb the target gas species at near ambient pressure.
44.
After filling a sorption pump with new molecular sieve it should always be regenerated as the new molecular sieve is probably saturated with water vapor.
45.

46.
The slow oxidation rate for some alcohols can be accelerated by the addition of molecular sieves, organic acids or acetic anhydride or of their combinations.
47.
The salt product may be purified by precipitation in a solution of anhydrous acetone An improvement to this process involves removing generated water with molecular sieves
48.
The ethanol is dehydrated to about 200 proof using a molecular sieve system and a denaturant such as gasoline is added to render the product undrinkable.
49.
Incorporation of transition metal complexes into the framework of molecular sieves is of consequence as it could lead to the development of new materials with catalytic properties.
50.
Yeast ferment these sugars into ethanol and carbon dioxide and the ethanol is purified through a combination of distillation and molecular sieve dehydration to create fuel ethanol.
