Iji Carbon Molecular Sieve mee ihe na nchekwa nri

    Ugbu a, a na-ejikarị nitrogen eme ihe na nchekwa nri, n'ihi na nitrogen bụ ihe na-adịghị arụ ọrụ nke ọma, N'okpuru ọnọdụ okpomọkụ na nrụgide nkịtị, ọtụtụ ihe agaghị eme ya. Iji nitrogen wezuga ikuku oxygen iji dozie ikuku nri dị ugbu a nwere ike belata ọrụ ikuku na igbochi metabolism na iku ume nke nri. N'otu oge, ọtụtụ microorganisms na-efunahụ ebe obibi ha.

    E nwere ụzọ ntanetị atọ dị ugbu a, ya bụ, nkewa ikuku nke cryogenic, nkewa ikuku ikuku na nkewa nkewa. The cryogenic ikuku nkewa osisi kwesịrị ekwesị n'ihi na nnukwu-ọnụ ọgụgụ ulo oru nitrogen mmepụta, na mgbagwoju akụrụngwa, nnukwu n'ala ebe, elu isi obodo ewu na-eri, nnukwu otu oge ego, elu ọrụ na-eri na-adịghị ngwa gas mmepụta. Ọ bụ ezie na akpụkpọ ahụ ikuku nkewa adabara obere na ọkara-sized nitrogen ọrụ, ọ bụ yiri molekụla myọ nke otu nkọwapụta The ngwá price nke ikuku nkewa usoro bụ karịa 15% elu karịa nke nke molekụla myọ ikuku nkewa usoro. The usoro eruba nke molekụla myọ ikuku nkewa usoro dị mfe, ogo akpaaka dị elu, na gas mmepụta bụ ngwa ngwa, na ume oriri bụ ala. Nke abuo, enwere ike idozi ịdị ọcha nke nitrogen dị ka mkpa nke ndị ọrụ n'ọtụtụ buru ibu, na-arụ ọrụ na ndozi dị mma, ụgwọ ọrụ dị ala, na ngbanwe siri ike nke ngwaọrụ ahụ.

    Ka ọ dị ugbu a, nrụpụta nitrogen site na ịgbanye adsorption (PSA) nke carbon molekul sieve dabere na ikuku dị ọcha dị ka ihe akụrụngwa na carbon molekụla sieve dị ka adsorbent. A na-eji ụkpụrụ nke PSA eme ihe carbon molekul sieve juputara na micropores selective adsorb gas molecule iji nweta nitrogen. Mgbe irighiri ihe ndị na-eme ka irighiri irighiri irighiri mmiri jupụta, a ga-ahapụrịrị ikuku oxygen n'ime oghere nke sel molekul maka ọrụ ọzọ. Mgbe a na-ewepụta mkpụrụ ndụ oxygen, a ga-ewepu carbon ahụ Nrụgide nke oyi akwa sel na-ebelata site na 0.3-0.6mpa ruo nrụgide nkịtị mgbe nrụgide nrụpụta. Nsogbu ikuku nke ikuku oxygen n'ime oghere nke ikuku molekul kariri nke ikuku oxygen. Oxygen na-asọpụta n'èzí site na oghere ahụ, a na-ewepụta mkpụrụ ndụ oxygen adsorbed site na oghere nke myọ molekụla.

    Ọ bụ ezie na usoro mmepụta nitrogen dị ugbu a nwere ike inye ikuku nitrogen maka nchekwa nri, mgbe ikuku jikọtara na-abanye n'ụlọ elu adsorption na nkesa carbon molekụla myọ, ikuku na-emetụta oke ọsọ na nkesa ahụ adịghị mma. Carbon molekul sieve dị mfe iti ma ọ bụ ọbụna pulverize, nke na-eme ka mmetụta adsorption ngwa ngwa ka njọ, arụmọrụ adsorption adịghị elu, ndụ ọrụ nke carbon molekụla sieve na-ebelata, na ịdị ọcha nke nitrogen mepụtara na-emetụta, nke kachasị dị mkpa Ọ dị mkpa iji nitrogen maka nchekwa nri, nke dị iche na ụlọ ọrụ. Ọ chọkwuru nitrogen dị ọcha iji kpuchido nri sitere na nje anaerobic na mmetọ ájá.

    Ya mere, ọ dị mkpa ịzụlite adsorption a na-agba ọsọ (PSA) sistemụ ikuku nke ikuku nitrogen maka nchekwa nri, nke nwere ike inye nitrogen dị ọcha ma mee ka ndụ ọrụ nke carbon molekụla sieve dịkwuo ogologo.
