Ọdịiche nke 3a 4a 5a molecular sieve

Kedu ihe dị iche n'etiti sieves 3a, 4a na 5a?A na-eji ụdị sieve molekụla atọ ndị a maka otu ebumnuche?Kedu ihe ndị metụtara ụkpụrụ ọrụ?Kedu ụlọ ọrụ dị mma maka?Bịa jiri JXKELLEY chọpụta.

1. Usoro kemịkalụ nke 3a 4a 5a molecular sieve

Usoro kemịkalụ molekụla sieve 3A: 2/3K₂O1₃·Na₂₂O·Al₂O₃·2SiO₂.·4.5H₂O

4A molecular sieve chemical formula: Na₂O·Al₂O₃·2SiO₂4.5H₂O

5A molekụla sieve usoro ọgwụ: 3/4CaO1/4Na₂OAl₂O₃·2SiO₂4.5H₂O

2. The pore size nke 3a 4a 5a molekụla sieve

Ụkpụrụ na-arụ ọrụ nke sieves molekụla metụtara nke ọma na nha nke sieves molecular, nke bụ 0.3nm/0.4nm/0.5nm n'otu n'otu.Ha nwere ike ịgbanye ụmụ irighiri gas nke dayameta molekụla ha dị obere karịa nha pore.Ka oke nha nke pore buru ibu, ka ikike mgbasa ozi na-abawanye.Ogo pore dị iche iche, ihe ndị a na-enyocha na nkewa dị iche iche dịkwa iche.N'okwu dị mfe, sieve molecular 3a nwere ike ịgbasa mkpụrụ ndụ dị n'okpuru 0.3nm, sieve molecular 4a, ụmụ irighiri ihe ndị a na-ekesa ga-enwerịrị ihe na-erughị 0.4nm, na sieve molecular 5a bụ otu ihe ahụ.Mgbe ejiri ya dị ka onye na-ekpochapụ ihe, sieve molecular nwere ike ịmịkọrọ ihe ruru 22% nke ịdị arọ ya na mmiri.

3. 3a 4a 5a molecular sieve ngwa ụlọ ọrụ

A na-ejikarị sieve molecular eme ihe maka ihicha mmanụ na-agbawa gas, olefin, gas refinery na gas oilfield, yana desiccant na chemical, pharmaceutical, iko mkpuchi na ụlọ ọrụ ndị ọzọ.A na-ejikarị eme ihe maka ihicha mmiri mmiri (dị ka ethanol), ihicha ikuku nke iko mkpuchi, nitrogen na hydrogen agwakọta gas ihicha, refrigerant ihicha, wdg.

A na-ejikarị sieves molekụla 4 maka ihicha gas sitere n'okike na gas dị iche iche kemịkalụ na mmiri mmiri, refrigerants, ọgwụ ọgwụ, data eletrọnịkị na ihe na-agbanwe agbanwe, na-eme ka argon dị ọcha, na ikewa methane, ethane na propane.A na-eji ya eme ihe maka ikpochapụ gas na mmiri mmiri dị ka ikuku, gas, hydrocarbons, refrigerant;nkwadebe na ịdị ọcha nke argon;static ihicha nke electronic components na ihe na-emebi emebi;ihe na-eme ka mmiri na-ekpo ọkụ na agba, polyesters, agba na mkpuchi.

A na-ejikarị sieve molecular mee ihe maka ihicha gas, desulfurization na mwepụ carbon dioxide;nkewa nke nitrogen na oxygen iji kwadebe oxygen, nitrogen na hydrogen;mmanụ ụgbọala dewaxing ikewapụ hydrocarbons nkịtị na hydrocarbons alaka na cyclic hydrocarbons.

Agbanyeghị, nnukwu mpaghara elu akọwapụtara na mgbasa ozi polar nke sieves molecular 5A nwere ike nweta nnabata miri emi nke mmiri na amonia fọdụrụnụ.Ngwakọta nitrogen-hydrogen mebiri emebi na-abanye n'igwe nkụ iji wepụ mmiri fọdụrụnụ na adịghị ọcha ndị ọzọ.Ngwa dị ọcha na-eji ụlọ elu adsorption okpukpu abụọ, otu na-amịkọrọ gas amonia akọrọ akọrọ, nke ọzọ na-emebi mmiri na amonia fọdụrụnụ na steeti kpụ ọkụ n'ọnụ (n'ozuzu 300-350 ℃) iji nweta ebumnuche nke ịmaliteghachi.Ugbu a, ị nwere ike nweta ọdịiche dị n'etiti sieves molecular 3a 4a 5a?
