Molecular sieve beads

[cyclopath]

I bake at 300F, over night, under vacuum.

I doubt that your nitrogen sweep is doing much to remove water from the beads unless you’re heating it first.

it is simple enough to test. take a handful of your dry beads. add a 1/4 cup of water. if you don’t have to drop them on the floor because they get too hot to handle, then they were not dry to start with (the absorption of water is exothermic).

Sourcing quality Molecular Sieve material

If your dehydrating etoh with seives, you will need to dry them to an acceptible level before heating them. Forced air ovens work well, just make sure your aren’t creating a fuel air mixture in your lab! 175-260c is an acceptible range to regenrate your seives. Make sure to let them cool under vaccum. If you want to test the seives you can add a small amount of water to the dehydrated beads, they will display an exothermic reaction and create heat.
