Carbon Chemistry 10A Molecular Sieve

Purifying gases and liquids,
Removing water vapor from hydrocarbons and alcohol vapor,
As a drying agent for solvents,
Beads can be reused – just reheat them in an oven, which dehydrates/reactivates them,
Can be used for removing carbon dioxide from streams of air passing over the beads.
Once these molecules are adsorbed by the pits or cracks in the beads, separation is increased. Smaller molecules will simply fall into the cracks/pores, while larger molecules will pass through unimpeded.
