11. Calcium hydride is a relatively mild desiccant and, compared to molecular sieves , probably inefficient. 12. Some use a molecular sieve that sorts oxygen from nitrogen, rendering the vapor inert. 13. Another form of electronic dry box technology utilizes multi-porous molecular sieve desiccants to adsorb moisture. 14. Under the term zeolites, molecular sieves are used for a wide range of catalytic applications. 15. Typical desiccants consist of silica gel, and molecular sieves . 16. The researchers who invented these types of particles planned to use them as molecular sieves . 17. In this process, ethanol vapor under pressure passes through a bed of molecular sieve beads. 18. Other processes include membrane separation, cryogenic fractionation, and adsorption using molecular sieves ( Herzog ). 19. Gases will now either condense or be adsorbed by the large surface of the molecular sieve . 20. They have framework structures similar to zeolites and some are used as catalysts or molecular sieves .
