Nigute ushobora gukoresha amashanyarazi ya 4A

Nigute ushobora gukoresha amashanyarazi ya 4A?Nibihe bisabwa kubidukikije bikoreramo? Nkibikoresho byoroshye, icyuma cya molekulari 4A gikoreshwa cyane mubice byinshi kubera icyuma cya microporome ya molekile yacyo nkibikoresho byo gutandukanya adsorption, ibikoresho byo guhana ion nibikoresho bya catalitiki.
Ubwa mbere, reka turebe intangiriro ya 4A ya molekile ya molekile:
Kubera ko ingano ya pore ikora neza ari 0.4nm, yitwa 4A molekile ya elegitoronike, ishobora guhuza ibice bike bya molekile nk'amazi, methanol, Ethanol, dioxyde de carbone, Ethylene, dioxyde de sulfure, hydrogen sulfide, na propylene.

• 1. Ingano ya molekulari yuburyo bwo gukoresha amashanyarazi ya 4A

Kuberako ubunini bwacyo bwiza bwa 0.4mm, ntibushobora kwamamaza molekile iyo ari yo yose (harimo na propane) ifite diameter irenze 0.4mm, ariko imikorere yayo ya adsorption yo mumazi iruta iyindi molekile, kandi ni bumwe muburyo butandukanye bukoreshwa cyane munganda.

• Ibidukikije bikora muburyo bwo gukoresha uburyo bwa 4A molekile

1. Iyo ubushyuhe buri hejuru ya 110 ° C, birashoboka guhumeka amazi mumwanya munini, ariko ntizirukana amazi mumyobo ya sikeli ya molekile. Kubwibyo, muri laboratoire, irashobora gukoreshwa no kubura umwuma mukumisha mu itanura. Ubushyuhe ni 350 ° C, kandi bwumishijwe munsi yumuvuduko usanzwe mumasaha 8 (niba hari pompe vacuum, irashobora gukama kuri 150 ° C mumasaha 5).
2.Icyuma gikora cya 4A gikonjesha gikonjeshwa kugeza kuri 200 ° C (hafi iminota 2) mukirere, kandi kigomba guhita kibikwa muri desiccator ako kanya.
3. Mu bidukikije byemewe, kurinda azote yumye bigomba gukoreshwa mugihe cyo gukonjesha no kubibungabunga, bishobora kubuza neza imyuka y’amazi yo mu kirere kutongera kwamamazwa. Kubera ko icyuma cya molekile gishaje nyuma yo gukoreshwa gifite umwanda, ntigomba gukoreshwa gusa ku bushyuhe bwa 450 ° C, ahubwo hagomba no gushyirwaho umwuka wamazi cyangwa gaze ya inert (azote, nibindi) kugirango bisimbuze ibindi bintu mumashanyarazi ya molekile.
4. Irinde amavuta namazi meza mugihe ukoresheje, kandi ugerageze kwirinda guhura namavuta namazi meza.
Nka aluminiyasi ya alkali, 4A molekile ya molekile itoneshwa nabakiriya benshi mukumisha gaze namazi, kandi irashobora no gukoreshwa mugutunganya no kweza gaze cyangwa amazi, nko gukuramo argon. Noneho, urumva ingamba zo kuyikoresha?
