Sida loo isticmaalo 4A shaandho molecular

Sida loo isticmaalo 4A shaandho molecular?Waa maxay shuruudaha deegaanka uu ka shaqeeyo?Sida wax daloolin ah, 4A shaandho molecular waxaa si ballaaran loo isticmaalaa in beero badan sababtoo ah shaandho molecular ay microporous sida walxaha kala soocida adsorption, wax beddelka ion iyo walxaha katalytic.
Marka hore, aan eegno hordhaca 4A shaandho molecular:
Sababtoo ah cabbirkeeda wax ku oolka ah ee daloolka waa 0.4nm, waxaa loo yaqaannaa 4A shaandho molecular, taas oo soo saari karta xeryahooda molecular hooseeya sida biyaha, methanol, ethanol, carbon dioxide, ethylene, sulfur dioxide, hydrogen sulfide, iyo propylene.

• 1. Cabbirka molecular ee habka isticmaalka 4A shaandho molecular

Sababtoo ah cabbirkeeda daloolada waxtarka leh waa 0.4mm, ma soo saari karto molecule kasta (oo ay ku jiraan propane) oo leh dhexroor ka weyn 0.4mm, laakiin waxqabadkeeda xayeysiinta ee biyaha ayaa ka sarreeya molecule kasta oo kale, waana mid ka mid ah molecular-ka ugu isticmaalka badan. noocyo shaandho in warshadaha.

• Deegaanka hawlgalka ee habka isticmaalka ee 4A shaandho molecular

1. Marka heerkulku yahay 110 ° C, waxaa suurtagal ah in la uumi-baxo biyaha meel bannaan, laakiin kama saari doono biyaha ku jira daloolada shaandhada molecular.Sidaa darteed, shaybaarka, waa la hawlgelin karaa oo fuuqbaxa marka lagu qalajiyo foornada muffle.Heerkulku waa 350 ° C, waxaana lagu qallajin karaa cadaadis caadi ah muddo 8 saacadood ah (haddii uu jiro bamka vacuum, waxaa lagu qallajin karaa 150 ° C ilaa 5 saacadood).
2. Shaandhooyinka molecular ee firfircoon ee 4A waxa lagu qaboojiyey ilaa 200°C (qiyaastii 2 daqiiqo) hawada, waxana loo baahan yahay in isla markiiba lagu kaydiyo qallajiye.
3. Deegaanka la ogol yahay, ilaalinta nitrogen ee qallalan waa in lagu dabaqaa inta lagu jiro qaboojinta iyo ilaalinta, taas oo si wax ku ool ah uga hortagi karta uumiga biyaha ee hawadu in mar kale la dhejiyo.Sababtoo ah shaandhada hore ee molecular ka dib isticmaalka ayaa leh wasakh, waa in aan la kicin oo kaliya heerkulka 450 ° C, laakiin sidoo kale uumiga biyaha ama gaasta aan shaqayn (nitrogen, iwm.) waa in la soo bandhigaa si loogu beddelo walxaha kale ee shaandhada molecular.
4. Ka fogow saliidda iyo biyaha dareeraha ah markaad isticmaalayso, iskuna day inaad ka fogaato xiriir toos ah oo saliid iyo biyo dareere ah.
Sida aluminosilicate bir alkali ah, 4A shaandho molecular waxaa doorbiday macaamiil badan oo qalajinta gaaska iyo dareeraha, waxaana sidoo kale loo isticmaali karaa sifeynta iyo nadiifinta gaaska ama dareeraha, sida soo saarista argon.Hadda, ma fahantay taxaddarrada isticmaalkeeda?
