ICarbon monoxide (CO) yigesi eyityhefu eqhelekileyo, enobungozi obukhulu kumzimba womntu kunye nokusingqongileyo.Kwiimveliso ezininzi zamashishini kunye nobomi bemihla ngemihla, isizukulwana kunye nokukhutshwa kwe-CO akunakugwenywa.Ke ngoko, kubalulekile ukuphuhlisa itekhnoloji esebenzayo kunye nesebenzayo yokususa i-CO.Izixhobo zentsimbi ezihloniphekileyo ziyiklasi ye-catalysts enomsebenzi ophezulu we-catalytic, ukukhetha kunye nokuzinza, ezisetyenziswa ngokubanzi ekususweni kwe-CO kunye nezinye iinkalo.
Iintlobo eziphambili kunye neempawu zeohloniphekileyoiicatalysts zentsimbi
ohloniphekileyoiicatalysts metal ikakhulu ziquka iplatinum (Pt), palladium (Pd), Iridium (Ir), rhodium (Rh), igolide (Au) kunye nezinye isinyithi.Ezi zinyithi zinezakhiwo zombane ezizodwa kunye namalungiselelo eathom ezivumela ukuba zibonise iipropati ezigqwesileyo kwii-catalysts.Ekususweni kwe-CO, iohloniphekileyoi-metal catalyst inokubangela ukuba i-CO iphendule nge-oksijini (O2) ukuvelisa i-carbon dioxide (CO2) engenabungozi.I-catalyst yensimbi ehloniphekileyo inomsebenzi ophezulu we-catalytic, ukukhetha okuphezulu kunye nokusebenza kakuhle kwe-poisoning, kwaye inokususa ngokufanelekileyo i-CO kwiqondo lokushisa eliphantsi.
Ukulungiselela indlela yeohloniphekileyoi-catalyst yesinyithi
Iindlela zokulungiselela zeohloniphekileyoi-catalyst yensimbi ikakhulu ibandakanya indlela yokukhulelwa, indlela yokunciphisa, indlela ye-sol-gel, njl.Ukuze kuphuculwe ukusebenza kweohloniphekileyoi-catalysts zetsimbi kunye nokunciphisa iindleko, abaphandi baye basebenzisa ukulayisha, i-nano kunye ne-alloying teknoloji.
Inkqubela phambili yophando malunga nokusetyenziswa kweecatalyst zentsimbi ezihloniphekileyo ekususweni kweCO
Inkqubela phambili ebalulekileyo yophando yenziwe ekusetyenzisweni kweohloniphekileyoiicatalysts zetsimbi ekususweni kweCO, ezifana:
4.1 Ukucocwa kombhobho wemoto:ohloniphekileyoiicatalysts zetsimbi zisetyenziswa ngokubanzi kwiinqwelo zokukhupha iimoto, ezinokususa ngokufanelekileyo iigesi ezinobungozi ezifana ne-CO, i-hydrocarbon compounds (HC) kunye ne-nitrogen oxides (NOx).Ukongeza, abaphandi baphonononga indibaniselwano yeohloniphekileyoi-catalysts zetsimbi kunye nezinye izinto ezisebenzayo zokuphucula ukusebenza kunye nokuzinza kwezicoci zokucoca iimoto.
4.2 Ukucoca umoya wangaphakathi: Ukusetyenziswa kweohloniphekileyoiicatalysts zetsimbi kwizicoci zomoya zangaphakathi ziye zatsala umdla ngakumbi nangakumbi, ezinokususa ngempumelelo iCO, i-formaldehyde, benzene kunye nezinye iigesi eziyingozi zangaphakathi.Abaphandi baphuhlisa ezintshaohloniphekileyoiicatalysts zetsimbi zokuphucula ukusebenza, ukunciphisa iindleko kunye nokunciphisa ubungakanani bezicoci zomoya zangaphakathi.
4.3 Unyango lwerhasi ye-industrial flue:ohloniphekileyoi-catalysts yensimbi inoluhlu olubanzi lwamathemba okusebenza kwintsimi yonyango lwegesi ye-industrial flue, njengemichiza, i-petroleum, insimbi kunye namanye amashishini.Abaphandi baphuhlisa ngokufanelekileyo kwaye bazinzileohloniphekileyoiicatalysts zetsimbi ukuhlangabezana neemfuno zonyango ezahlukeneyo igesi flue kushishino.
4.4 Iiseli zamafutha:ohloniphekileyoiicatalysts zetsimbi zidlala indima ebalulekileyo kwiiseli zamafutha, zikhuthaza ukuveliswa kwamanzi kunye nombane kwi-hydrogen kunye ne-oxygen.Abaphandi baphonononga uyilo kunye nokulungiswa kwezinto ezintshaohloniphekileyoiicatalysts zetsimbi ukuphucula ukusebenza kunye nokuqina kweeseli zamafutha.
Isishwankathelo
ohloniphekileyoiicatalysts zetsimbi zineenzuzo ezibalulekileyo ekususweni kwekhabhon monoxide, kwaye zenze inkqubela ebalulekileyo yophando kwimimandla yokucocwa kwegesi yokukhupha inqwelo-mafutha, ukucocwa komoya wangaphakathi, unyango lwegesi ye-industrial flue kunye neeseli zamafutha.Nangona kunjalo, ixabiso eliphezulu kunye nokunqaba kweohloniphekileyoiicatalysts zentsimbi zihlala ziyimingeni ephambili yophuhliso lwabo.Uphando lwexesha elizayo kufuneka lugxininise kwindlela yokudibanisa, ukuphuculwa komsebenzi, ukunciphisa iindleko kunye nokuzinzaohloniphekileyoiicatalyst zetsimbi ukukhuthaza ukusetyenziswa ngokubanzi kweohloniphekileyoi-catalysts zetsimbi kwintsimi yokususwa kwe-carbon monoxide.
