Author: Subject: Drying Molecular Sieve in a Microwave Oven

3A zeolite ceramic molecular sieve pellets used for solvent drying in the EM lab can only absorb so much water and then need to be heated to 250C to regenerate by driving off the water. Most lab ovens are rated 1 to 2 kW and barely get to 250C. This is both marginal for drying and wastes a lot of energy to bake out a small volume of sieves.

For optimum regeneration, gas flow should be countercurrent to adsorption during the heatup cycle, and concurrent (relative to the process stream) during cooling. Alternatively, small quantities of molecular sieves may be dried in the absence of a purge gas by oven heating followed by slow cooling in a closed system, such as a desiccator.

Jan 10, 2016 · Typically, this equates to 6 or 7 cycles in total to dry about 25 grams of sieves. This works very well to produce sieves for drying ethanol. However, if you prefer a "set and forget" procedure, I don't think anything can beat placing sieves in a small oven set to above 250 C for a couple hours. [Edited on 1-10-2016 by Cryolite.]

Unfortunately, sieves are shipped saturated with water and must be dried before use. Sieves actually absorb water at 120 degC, so a conventional drying oven is not up to the task. Conventional wisdom is that heating to 300 degC or greater at atmospheric pressure will dry sieves, and this temperature can be reduced somewhat under vacuum [3].
