IBIKORWA BYA MINERAL, INGINGO ZA FILTER, N'IBIKORWA BIKURIKIRA
Amashanyarazi ya molekuline ni kristaline yicyuma ya aluminosilicates ifite urusobekerane rwihuza rwimikorere ya silika na tetrahedra ya alumina. Amazi asanzwe ya hydratiya akurwa kururu rusobe ashyushya kugirango habeho imyenge imwe ihitamo adsorb molekules zingana.
Isoko ya 4 kugeza 8-mesh isanzwe ikoreshwa mugukoresha gasphase, mugihe ubwoko bwa 8 kugeza 12-mesh busanzwe mubisabwa mumazi. Ifu yifu ya 3A, 4A, 5A na 13X ya sike ikwiranye nibisabwa byihariye.
Kuva kera bizwiho ubushobozi bwo kumisha (ndetse kugeza kuri 90 ° C), amashanyarazi ya molekile aherutse kwerekana akamaro muburyo bukoreshwa muburyo bwa organic syntique, akenshi bituma habaho gutandukanya ibicuruzwa byifuzwa bivuye mubitekerezo bya kondegene bigengwa nuburinganire bubi. Izi zeolite ya syntetique yerekanwe gukuraho amazi, alcool (harimo methanol na Ethanol), na HCl muri sisitemu nka ketimine na enamine synthes, ester condensations, hamwe no guhindura aldehydes idahagije kuri polyenal.
| Andika | 3A |
| Ibigize | 0.6 K2O: 0.40 Na2O: 1 Al2O3: 2.0 ± 0.1SiO2: x H2O |
| Ibisobanuro | Ifishi ya 3A ikorwa mugusimbuza potasiyumu cations kubisanzwe bya sodium ion yimiterere ya 4A, bikagabanya ubunini bwa pore bugera kuri ~ 3Å, ukuyemo diameter> 3Å, urugero, Ethane. |
| Porogaramu Nkuru | Umwuma wo gucuruza amazi ya hydrocarubone idahagije, harimo gaze yacitse, propylene, butadiene, acetylene; kumisha amazi ya polar nka methanol na Ethanol. Kwiyongera kwa molekile nka NH3 na H2O kuva N2 / H2. Ufatwa nkibikorwa rusange byo kumisha muri polar hamwe nibitangazamakuru bidafite inkingi. |
| Andika | 4A |
| Ibigize | 1 Na2O: 1 Al2O3: 2.0 ± 0.1 SiO2: x H2O |
| Ibisobanuro | Iyi fomu ya sodiumi yerekana ubwoko A umuryango wibikoresho bya molekile. Gufungura neza pore ni 4Å, ukuyemo molekile ya diameter ikora neza> 4Å, urugero, propane. |
| Porogaramu Nkuru | Bikundwa no kubura umwuma muri sisitemu ifunze ya gaze cyangwa gaze, urugero, mugupakira ibiyobyabwenge, ibikoresho byamashanyarazi nimiti yangirika; gushakisha amazi muri sisitemu yo gucapa na plastike no kumisha imigezi ya hydrocarubone yuzuye.Ibinyabuzima byemewe birimo SO2, CO2, H2S, C2H4, C2H6, na C3H6. Mubisanzwe bifatwa nkibikoresho byo kumisha isi yose mubitangazamakuru bya polar. |
| Andika | 5A |
| Ibigize | 0.80 CaO: 0.20 Na2O: 1 Al2O3: 2.0 ± 0.1 SiO2: x H2O |
| Ibisobanuro | Intungamubiri za calcium ion mu mwanya wa sodium cations zitanga aperture ya ~ 5Å ukuyemo molekile ya diameter ikora neza> 5Å, urugero, impeta zose za 4-karubone, hamwe na iso-compound. |
| Porogaramu Nkuru | Gutandukanya paraffine zisanzwe ziva mumashami-ya hydrocarbone ya cycle; kuvanaho H2S, CO2 na mercaptans muri gaze gasanzwe. Molekules yamamajwe harimo nC4H10, nC4H9OH, C3H8 kugeza C22H46, na dichlorodifluoro-methane (Freon 12®). |
| Andika | 13X |
| Ibigize | 1 Na2O: 1 Al2O3: 2.8 ± 0.2 SiO2: xH2O |
| Ibisobanuro | Ifishi ya sodiumi yerekana ibyingenzi byubwoko bwumuryango X, hamwe no gufungura pore neza murwego 910¼. Ntabwo azamamaza (C4F9) 3N, kurugero. |
| Porogaramu Nkuru | Kuma gazi yubucuruzi, kweza ibihingwa byangiza ikirere (kuvanaho icyarimwe H2O na CO2) hamwe na hydrocarubone y'amazi / uburyohe bwa gaze karemano (H2S no gukuraho mercaptan). |
