Tinozivei pamusoro carbon dioxide inobvisa?

Carbon dioxide (CO ₂₎ - gasi ine haawanzotauri oneka anovava kuravira, asina ruvara kana kwakanaka. wevasungwa yayo mumhepo Nyika iri Paavhareji vanenge 0,04%. Kudivi rimwe, kuramba upenyu iye zvachose kukodzera. Nokuno rumwe - zvose zvinomera nyore vangadai vakafa vasina carbon dioxide, sezvo iye ari "tsime simba" nokuda chirimwa. Uyezve, nokuti Earth _CO2 zviri gumbeze zvimwe mhando. Kana mumhepo paiva gasi ichi, redu kwaizova unotonhorera zvikuru uye mvura inonaya zvaizoguma zvinenge zvachose.

"Bhurangeti Earth»

Nezvekugadzirwa carbon dioxide inobvisa (carbon dioxide, CO ₂₎ mugumisiro maererano zviviri yenhengo dzayo: oxygen kabhoni. gasi ichi chakaumbwa kwose kwose kunodiwa zimbe kana yeHydrocarbon yeimwe. Zvinonzi zvakare asunungurwa panguva chinovira kuti mvura uye sezvo rakavapo mhuka uye afemeruke kwevanhu. Kusvika panguva ehupfumi kuti carbon dioxide inobvisa vari zvakanaka kudzidza. Zvinozivikanwa kuti gasi ichi kunorema kupfuura mhepo uye Hauoneki. Kana pamwe mvura, anoumba carbonic acid, iro zvinowanzoshandiswa ose carbonated hwahwa.

Nei masayendisiti kazhinji kutaura kuti CO ₂ - a pamucheka nyika yedu? Chokwadi chokuti carbon dioxide inobvisa pemipata pachena kuuya kwatiri kubva muchadenga ultraviolet mwaranzi ndokufunga michini nemwaranzi chaibwinya ne Earth. Naizvozvo pakarepo kunyangarika gasi kubva mumhepo zvikurukuru kuti sei mwaka. Zvisinei, mukana petsaona kwakadaro kushanda razero, kubva combustion huni, negasi, marasha uye mafuta zvishoma nezvishoma kunowedzera wevasungwa kuti carbon dioxide inobvisa mumhepo. Zvino kutya kunyange kunze kuchitonhora, sezvo vakawanda kubvunda echando ari matanda uye kuwedzera huwandu nyanza ...

yakaoma chando

In nemvura mamiriro gasi anochengeterwa sepombi panguva pamatunhu kumanikidzwa (anenge 70 ATM). Kana iwe kuzarura vharuvhu yacho simbi mudziyo kubva mugomba anotanga ukadarika ... chando. Ko zvishamiso mhando? Izvi zvinotsanangurwa zvikuru nyore. Panguva compression carbon dioxide kuti wakapedza basa, izvo nokukura zviri substantially zvishoma pane kuti zvakafanira kuti kuwedzera kwayo. Kuti aripire kushayiwa ichibudira CO ₂ ukadzimwa uye ichachinjwa kuva "chando chakaoma". Achienzaniswa ane kwakajairika chando ine nhamba zvinokosha zvakanakira: Chokutanga, ayo kwemvura kunoitika zvachose pasina inotungamirwa residues. Uye chechipiri, kuti "kutonhora simba" yakaoma chando paminiti chikwata uremu kaviri.

kunyoresa

Carbon dioxide inowanzoshandiswa sechinhu inert unosvikirwa ari nomoto waya. Zvisinei, panguva yakakwirira tembiricha manyowa kunoitika pakabudiswa kwayo oxidizing simbi yakachena. Naizvozvo, kuti nomoto waya iri akawedzera scavengers, akadai nesilicon uye manganese. Carbon dioxide mu magaba yaiwanzoshandiswa pneumatic pfuti uye Aviamodelirovaniye. The mvura gasi rinoshandiswa somoto chokudzimisa hwokubereka pasoda uye remonedhi. Uyezve, CO2 Carbon dioxide rinoshandiswawo sezvokudya chirungiso (E290) code. Uye sezvo tose tinoziva zvinoreva kuti kusunungura mukanyiwa. Kunze, hwakasimba kabhoni dioxide zvikuru kushandiswa kuchengetedza zvokudya zvinogadzirwa.
