3A Molecular Sieve Rau Ethanol Dehydration
Molecular sieves yog aluminosilicate compounds nrog lub cubic lattice. Nws muaj cov qauv microporous zoo ib yam, thiab molecular sieves muaj cov pore diameters sib xws. Cov pores no tuaj yeem nqus cov molecules me dua li lawv txoj kab uas hla mus rau sab hauv ntawm qhov pore kab noj hniav, thiab muaj qhov zoo tshaj plaws adsorption muaj peev xwm rau polar molecules thiab unsaturated molecules. Molecules nrog ntau qib ntawm solubility, sib txawv degrees ntawm saturation, sib txawv molecular ntau thiab tsawg ntawm boiling ntsiab lus yog sib cais, uas yog, lawv muaj lub luag hauj lwm ntawm "sieving" molecules, yog li lawv hu ua molecular sieves. Rau ethanol-dej system, txij li qhov tseem ceeb molecular diameters ntawm dej thiab ethanol yog 2.7 angstroms thiab 4.7 angstroms feem, dej molecules tuaj yeem nkag mus rau sab hauv ntawm 3 angstrom molecular sieve thiab raug adsorbed ntawm molecular sieve los ntawm lub zog polar attraction. molecular sieve rau dej. sab hauv, thaum ethanol molecules raug thaiv sab nraud, kom paub txog kev xaiv adsorption thiab sib cais ntawm dej thiab ethanol.
Cov kev siv tshwj xeeb yog: kev ziab kom qhuav ntawm cov roj av tawg, ethylene, propylene, butadiene, acetylene (que) thiab lwm yam roj, nws tuaj yeem siv rau ziab cov kua (xws li ethanol, acetone), thiab nws kuj tuaj yeem siv rau ziab. hauv kev kho mob, zaub mov thiab lwm yam lag luam. tus neeg sawv cev. . Tsis tas li ntawd, nws kuj tau siv dav hauv kev lag luam iav insulating.
