Ebumnuche: Carbon Molecular sieve bụ ihe ọhụrụ e mepụtara na 1970s, ọ bụ ihe dị mma nke na-abụghị polar carbon, Carbon Molecular Sieves (CMS) ejiri kewaa nitrogen nke na-eme ka ikuku baa uru, na-eji usoro nitrogen dị ala n'ime ụlọ, karịa usoro nitrogen dị elu nke dị omimi nke ukwuu nke ọdịnala nwere obere ego itinye ego, ọsọ mmepụta nitrogen dị elu na obere ọnụ ahịa nitrogen. Ya mere, ọ bụ ihe kachasị amasị ụlọ ọrụ injinia maka nkewa ikuku nitrogen bara ụba na-adọrọ adọrọ (PSA), a na-ejikarị nitrogen a eme ihe n'ụlọ ọrụ kemịkalụ, ụlọ ọrụ mmanụ na gas, ụlọ ọrụ eletrọnịkị, ụlọ ọrụ nri, ụlọ ọrụ kol, ụlọ ọrụ ọgwụ, ụlọ ọrụ eriri, ọgwụgwọ okpomọkụ ígwè, njem na nchekwa na akụkụ ndị ọzọ.

Ụkpụrụ ọrụ: Mkpọpụta molekul carbon bụ iji njirimara nyocha iji nweta nkewa nke oxygen na nitrogen. Na mkpọpụta molekul sieve nke gas na-adịghị ọcha, nnukwu na mesoporous na-arụ naanị ọrụ nke ọwa ahụ, a ga-ebuga molekul ndị a na-etinye n'ime micropores na submicropores, micropores na submicropores bụ ezigbo olu nke mkpọpụta. Dịka egosiri na eserese gara aga, mkpọpụta molekul carbon nwere ọtụtụ micropores, nke na-enye molekul ndị nwere obere kinetic nha ịgbasa ngwa ngwa n'ime pores, ebe ha na-egbochi ntinye nke nnukwu molekul dayameta. N'ihi ọdịiche dị na ọnụego mgbasa ozi nke molekul gas nke nha dị iche iche, enwere ike kewaa ihe mejupụtara ngwakọta gas nke ọma. Ya mere, nkesa nke micropores na mkpọpụta molekul carbon kwesịrị ịdị site na 0.28 nm ruo 0.38 nm dịka nha molekul si dị. N'ime oke nha micropore, oxygen nwere ike ịgbasa ngwa ngwa n'ime pore site na mkpọpụta molekul, mana nitrogen siri ike ịgafe site na mkpọpụta molekul, iji nweta nkewa nke oxygen na nitrogen. Nha oghere micropore bụ ntọala nkewa carbon molekul sieve nke oxygen na nitrogen, ọ bụrụ na nha oghere ahụ buru ibu nke ukwuu, oxygen na nitrogen dị mfe ịbanye na micropore sieve molekul, ha enweghịkwa ike ịrụ ọrụ nkewa; Nha oghere ahụ pere mpe, oxygen, nitrogen enweghị ike ịbanye na micropore ahụ, enweghịkwa ike ịrụ ọrụ nkewa.

Ngwaọrụ nitrogen nkewa ikuku carbon: a na-akpọkarị ngwaọrụ ahụ igwe nitrogen. Usoro teknụzụ bụ usoro ntinye nrụgide (usoro PSA maka mkpụmkpụ) na okpomọkụ nkịtị. Ntinye nrụgide nrụgide bụ usoro ntinye na nkewa na-enweghị isi iyi okpomọkụ. A na-etinye ikike ntinye nke sieve molekul carbon na ihe ndị a na-etinye n'ime mmiri (karịsịa molekul oxygen) n'oge ntinye nrụgide na mmepụta gas n'ihi ụkpụrụ dị n'elu, yana mwepụ n'oge mbelata nrụgide na ikuku, iji mee ka sieve molekul carbon dịghachi ọhụrụ. N'otu oge ahụ, nitrogen bara ụba na usoro gas akwa na-agafe n'elu akwa ahụ ka ọ bụrụ gas ngwaahịa, nzọụkwụ ọ bụla bụkwa ọrụ okirikiri. Ọrụ okirikiri nke usoro PSA gụnyere: chaja nrụgide na mmepụta gas; Nrụgide otu; Nkwụsị, ikuku; Mgbe ahụ nrụgide, mmepụta gas; Ọtụtụ usoro ọrụ, na-emepụta usoro ọrụ okirikiri. Dịka ụzọ dị iche iche nke usoro ahụ si dị, enwere ike kewaa ya n'ime usoro mweghachi ikuku na usoro mweghachi ikuku. Ngwa igwe PSA nitrogen dịka mkpa ndị ọrụ si dị nwere ike ịgụnye sistemụ nhicha ikuku, sistemụ adsorption nrụgide, usoro njikwa valvụ (mmeghari ikuku kwesịkwara inwe mgbapụta ikuku), na sistemụ ọkọnọ nitrogen.
