Mokhoa oa ho sebelisa 4A sieve ea molek'hule

Mokhoa oa ho sebelisa sieve ea molek'hule ea 4A joang?Ke lintho life tse hlokahalang bakeng sa tikoloho eo e sebetsang ho eona?Joalo ka sesebelisoa sa porous, 4A sieve ea limolek'hule e sebelisoa haholo libakeng tse ngata ka lebaka la sieve ea eona ea limolek'hule tse nyane e le thepa ea karohano ea adsorption, thepa ea phapanyetsano ea ion le lintho tse thusang.
Taba ea pele, a re shebeng kenyelletso ea 4A molecular sieve:
Hobane boholo ba eona bo sebetsang ba pore ke 0.4nm, e bitsoa 4A molecular sieve, e ka khonang ho sebelisa metsoako e tlaase ea molek'hule e kang metsi, methanol, ethanol, carbon dioxide, ethylene, sulfur dioxide, hydrogen sulfide le propylene.

• 1. Boholo ba molek'hule ea mokhoa oa ho sebelisa 4A sieve ea molek'hule

Hobane boholo ba pore ea eona e sebetsang hantle ke 0.4mm, ha e khone ho khahlisa molek'hule leha e le efe (ho kenyeletsoa propane) e bophara bo boholo ho feta 0.4mm, empa ts'ebetso ea eona ea khetho ea metsi e phahame ho feta molek'hule leha e le efe, 'me ke e' ngoe ea limolek'hule tse sebelisoang ka ho fetisisa. mefuta e sa tšoaneng ea sieve indastering.

• Tikoloho ea ts'ebetso ea ts'ebeliso ea mokhoa oa 4A molecular sieve

1. Ha mocheso o le 110 ° C, hoa khoneha ho etsa mouoane oa metsi sebakeng se seholo, empa ho ke ke ha leleka metsi ka har'a li-pores tsa sieve ea molek'hule.Ka hona, ka laboratoring, e ka sebelisoa le ho felloa ke metsi ka ho omisa ka sebōping sa muffle.Mocheso ke 350 ° C, 'me o omisitsoe tlas'a khatello e tloaelehileng bakeng sa lihora tse 8 (haeba ho na le pompo ea vacuum, e ka omisoa ka 150 ° C lihora tse 5).
2. Sieve ea molek'hule ea 4A e kentsoeng e pholile hoo e ka bang 200 ° C (hoo e ka bang metsotso e 2) moeeng, 'me e hloka ho bolokoa ka har'a desiccator hang-hang.
3. Sebakeng se lumelletsoeng, tšireletso e omeletseng ea naetrojene e lokela ho sebelisoa nakong ea ho pholile le ho e boloka, e ka thibelang ka katleho hore mouoane oa metsi o moeeng o se ke oa ba adsorbed hape.Hobane sieve ea khale ea molek'hule ka mor'a hore e sebelisoe e na le litšila, ha ea lokela ho sebelisoa feela ka mocheso oa 450 ° C, empa hape le mouoane oa metsi kapa khase ea inert (naetrojene, joalo-joalo) e lokela ho kenngoa ho nkela lintho tse ling sebaka sa limolek'hule tsa sieve.
4. Qoba oli le metsi a metsi ha u sebelisa, 'me u leke ho qoba ho kopana ka ho toba le oli le metsi a metsi.
Joaloka aluminosilicate ea tšepe ea alkali, 4A sieve ea molek'hule e ratoa ke bareki ba bangata ha ho omisoa ha khase le metsi, hape e ka sebelisoa bakeng sa ho hloekisa le ho hloekisa khase kapa metsi, joalo ka ho ntša argon.Joale, na u utloisisa litemoso bakeng sa tšebeliso ea eona?
