Nokuhlanzwa okhanda amanye amathuba amagesi

I ukungcola okwandisa emoyeni kuyinto engathí sina, futhi ngenxa yalokho wokuhlanza of igesi encane ebamba liba nakakhulu njalo ngonyaka. Umthombo elikhulu amagesi ayingozi emoyeni kukhona izimboni amandla ngemgwaco.

Ukuhlanzwa amagesi kwenziwa ngezindlela ezihlukahlukene, futhi phakathi lapho ephumelela kunazo ezimweni eziningi indlela okhanda amanye amathuba ngoba ukungaqaliswa nokwehlisa lokuhlushwa ezingcolisayo ukuze esiphezulu ezingeni kuvunyelwe. yokuhlanza Catalytic luncanyelwa, futhi ngenxa yezizathu zezomnotho.

Ngokuvamile, izindlela okhanda amanye amathuba kukhona jikelele futhi ingasetshenziswa yokuhlanza ezijulile inqubo amagesi ahlukahlukene. Nale ndlela kungenzeka ukuhlanza amagesi zezimboni kusukela nitrogen oxides nesibabule, i-carbon monoxide, compounds eziyingozi eziphilayo kanye nezinye izinto ezinobuthi. Kulokhu ezingcolisa aguqulwa ku ayiyona ingozi nabangenacala, futhi ngezinye izikhathi ngisho ewusizo. Indlela efanayo Kwenziwa uhlanzekile of qeda amagesi. Empeleni, indlela siqukethe ekusebentiseni izinqubo nokuxhumana amakhemikhali izinto ebukhoneni catalysts, okuholela ukuguqulwa amanyela ukuba neutralization, ku neminye imikhiqizo.

yelikhono Special ukusheshisa zamakhemikhali, kodwa musa kuthinte amandla ezingeni yezinhlayiya uxhumana hhayi azixoshe le yakhoibrium ukusabela elula. nokuhlanzwa Catalytic ezithembisa ngoba Izingxube multicomponent ka flue igesi ukusakaza. Ukuze gas yokuhlanza e umkhakha ezisetshenziswa njengeziwusizo yelikhono oxides of iron, ithusi, i-chromium, ayibe, zinc, i-platinum nabanye. Lezi izinto kusetshenzwe kulethe ukwesekwa ufakwa ophendulayo iyunithi. Kuyadingeka ukuqapha ubuqotho yangaphandle kulethe ungqimba, kungenjalo sokuhlanzwa okhanda amanye amathuba ngeke waqaphela isihenqo esigcwele, futhi ekushayweni izidakamizwa eziyingozi lingadlula ukunqunyelwa kuvunyelwe.

Le mfuneko esemqoka iwukuthi ekwandeni - ukuzinza isakhiwo ngesikhathi yokusabela. Ukucinga futhi enza catalysts akuyona kuphela ezifanelekela ukusetshenziswa isikhathi eside kodwa futhi ngempela ezishibhile, kuyinto ebunzimeni obuthile, okwenza zilinganiselwe izinhlobo isicelo indlela okhanda amanye amathuba. yelikhono Modern kufanele ifa selectivity nomsebenzi, ukumelana okushisa namandla lokukhanda.

Industrial yelikhono enziwa ngendlela amabhlogo kanye lezinyosi izindandatho. Banezinhliziyo ongaphakeme ukugeleza ukumelana naso futhi kwenze okusezingeni eliphezulu yangaphandle surface area. I esetshenziswa njalo kunazo uhlanzekile okhanda amanye amathuba yamagesi e kulethe isilungisiwe.

Ngo umkhakha zingasebenzisa izindlela ezimbili ngokuyinhloko ezahlukene izinqubo ukwelashwa igesi - Imodi umile futhi nonstationary eyayenziwe wadala. Inguquko nokusetshenziswa eyinhloko indlela kungenxa ongagxilile ephakeme inqubo processability, ukwandisa ukuphendula rates, anda selectivity, amandla ukusetshenziswa ukunciphisa izinqubo, nokuncipha ukufakwa nemali yokuqhuba kanye nokwehla izindleko zawo.

Isiqondiso eyinhloko ukuthuthukiswa amasu okhanda amanye amathuba ukunikeza yelikhono ezishibhile uyakwazi ukusebenza ngaphansi kwamazinga okushisa aphansi futhi amelana izinto ezihlukahlukene. Ukuze lokuhlala ngezansi 1 g / m³ kanye lemiqulu emikhulu igesi bahlanza indlela thermocatalytic kudinga amandla okusezingeni eliphezulu kanye nenani elikhulu kulethe, ngakho kunesidingo ukuthuthukisa esiphezulu kwagezi izinqubo kanye nemishini ezidinga ongaphakeme dolobha izindleko.
