Yadda ake amfani da sieve kwayoyin 4A?Menene bukatun muhallin da yake aiki a ciki?A matsayin porous abu, 4A kwayoyin sieve ne yadu amfani a da yawa filayen saboda ta microporous kwayoyin sieve matsayin adsorption rabuwa abu, ion musayar abu da catalytic abu.
Da farko, bari mu kalli gabatarwar 4A keɓaɓɓen sieve:
Saboda girman girmansa mai inganci shine 0.4nm, ana kiransa 4A molecular sieve, wanda zai iya tallata ƙananan mahadi na ƙwayoyin cuta kamar ruwa, methanol, ethanol, carbon dioxide, ethylene, sulfur dioxide, hydrogen sulfide, da propylene.
- 1. Girman kwayoyin hanyar yin amfani da simintin kwayoyin 4A
Saboda girman pore ɗin sa mai inganci shine 0.4mm, ba zai iya haɗa kowane kwayar halitta (ciki har da propane) mai diamita mafi girma fiye da 0.4mm, amma zaɓin tallan da yake yi na ruwa ya fi kowane kwayoyin halitta, kuma yana ɗaya daga cikin mafi yawan amfani da kwayoyin halitta. sieve iri a masana'antu.
- Yanayin aiki na hanyar amfani da sieve kwayoyin 4A
1. Lokacin da zafin jiki ya kasance 110 ° C, yana yiwuwa a zubar da ruwa a cikin babban sararin samaniya, amma ba zai fitar da ruwa a cikin ramukan ƙwayar kwayoyin halitta ba.Sabili da haka, a cikin dakin gwaje-gwaje, ana iya kunna shi kuma ya bushe ta bushewa a cikin tanderun murfi.Yanayin zafin jiki shine 350 ° C, kuma ana bushe shi a ƙarƙashin matsin lamba na tsawon sa'o'i 8 (idan akwai famfo, za a iya bushe shi a 150 ° C na 5 hours).
2. Ana sanyaya sieve molecular 4A da aka kunna zuwa kusan 200 ° C (kimanin mintuna 2) a cikin iska, kuma yana buƙatar adana shi a cikin injin bushewa nan da nan.
3. A cikin yanayin da aka ba da izini, ya kamata a yi amfani da kariya ta nitrogen mai bushe a lokacin sanyaya da adanawa, wanda zai iya hana tururin ruwa a cikin iska daga sake sakewa.Domin tsohuwar simintin kwayoyin bayan amfani da shi yana da gurɓatacce, bai kamata a kunna shi a zafin jiki na 450 ° C kawai ba, amma kuma a shigar da tururin ruwa ko iskar gas (nitrogen, da dai sauransu) don maye gurbin wasu abubuwa a cikin sieve kwayoyin.
4. A guji mai da ruwa lokacin amfani da shi, kuma a yi ƙoƙarin guje wa hulɗa da mai da ruwan ruwa kai tsaye.
A matsayin alkali karfe aluminosilicate, 4A kwayoyin sieve ne falala da yawa abokan ciniki a bushewa na gas da ruwa, kuma za a iya amfani da su refining da tsarkakewa na gas ko ruwa, kamar hakar na argon.Yanzu, kun fahimci matakan kariya don amfani da shi?
