Yes, and you probably did. This is why they use distillation columns in industry. Zeolytes should work. Just make sure that whatever one you choose is capable of absorbing water. Not all zeolytes are designed for the same capability. While porosity may be the wrong word to define how they're constructed, zeolytes are engineered to absorb specific sized molecules.
