Carbon monoxide (CO) igasi rine muchetura, iro rine kukuvadza kukuru kumuviri wemunhu uye nharaunda.Mukugadzirwa kwakawanda kwemaindasitiri uye hupenyu hwezuva nezuva, chizvarwa uye kubuda kweCO hazvigoneke.Saka, zvakakosha kukudziridza hunobudirira uye hunobudirira CO kubvisa michina.Noble metal catalysts ikirasi yezvigadziridzo zvine high catalytic chiitiko, selectivity uye kugadzikana, iyo inoshandiswa zvakanyanya mukubvisa CO uye mamwe minda.
Mhando huru uye zvivakwa zvenoblemetal catalysts
noblesimbi catalysts kunyanya zvinosanganisira platinum (Pt), palladium (Pd), Iridium (Ir), rhodium (Rh), goridhe (Au) uye dzimwe simbi.Masimbi aya ane akasiyana emagetsi zvimiro uye hurongwa hweatomu hunovatendera kuratidza zvakanakisa zvivakwa mumacatalysts.Mukubviswa kweCO, iyonoblemetal catalyst inogona kuita kuti CO iite neokisijeni (O2) kuti ibudise isingakuvadzi kabhoni dhaikisaidhi (CO2).Iyo inoyevedza simbi inokonzeresa ine yakakwira catalytic chiitiko, yakakwira kusarudza uye yakanaka anti-chepfu kuita, uye inogona kunyatso bvisa CO pane yakaderera tembiricha.
Kugadzirira nzira yenoblemetal catalyst
Nzira dzekugadzirira dzenoblesimbi catalyst inonyanya kusanganisira impregnation nzira, coprecipitation nzira, sol-gel nzira, etc. Nzira imwe neimwe ine zvayakanakira nezvayakaipira maererano nekuita kwekuita, mutengo uye kushanda.Kuti uvandudze mashandiro enoblemetal catalysts uye kuderedza mutengo, vaongorori vakashandisawo kurodha, nano uye alloying matekinoroji.
Tsvagiridzo inofambira mberi pakushandiswa kweanoble metal catalysts mukubvisa CO
Kufambira mberi kwetsvakiridzo kwakakosha kwakaitwa mukushandiswa kwenoblesimbi catalysts mukubvisa CO, senge:
4.1 Kucheneswa kwemoto wemoto:noblemetal catalysts anoshandiswa zvakanyanya mumotokari exhaust purifiers, anogona kubvisa zvinokuvadza magasi akadai CO, hydrocarbon compounds (HC) uye nitrogen oxides (NOx).Mukuwedzera, vatsvakurudzi vari kuongororawo kusanganiswa kwenoblemetal catalysts nezvimwe zvinoshanda zvekuvandudza mashandiro uye kugadzikana kwemotokari exhaust purifiers.
4.2 Kucheneswa kwemhepo yemukati: Kushandiswa kwenoblesimbi inokonzeresa mumhepo yekuchenesa mukati yakwezva kutarisisa kwakawanda, iyo inogona kunyatso kubvisa CO, formaldehyde, benzene uye mamwe magasi anokuvadza emukati.Vatsvakurudzi vari kugadzirawo zvitsvanoblemetal catalysts yekuvandudza mashandiro, kuderedza mutengo uye kuderedza saizi yemukati memhepo inochenesa.
4.3 Industrial flue gasi kurapwa:noblesimbi catalysts ane akasiyana-siyana ekushandisa tarisiro mumunda weindasitiri flue gasi kurapwa, senge makemikari, petroleum, simbi uye mamwe maindasitiri.Vatsvakurudzi vari kuwedzera kubudirira uye kugadzikananoblesimbi catalysts kusangana nezvinodiwa siyana maindasitiri flue gasi kurapwa.
4.4 Masero emafuta:noblemetal catalysts inoita basa rakakosha mumasero emafuta, zvichikonzera kugadzirwa kwemvura nemagetsi kubva kuhydrogen neokisijeni.Vatsvagiri vari kuongorora dhizaini uye optimization yezvitsvanoblemetal catalysts yekuvandudza mashandiro uye kusimba kwemafuta masero.
Summary
noblemetal catalysts zvine zvakanakira kubviswa kwekabhoni monoxide, uye vakaita zvakakosha tsvakiridzo kufambira mberi muminda yemotokari inopedza gasi kucheneswa, kucheneswa kwemweya wemukati, kurapwa kwegasi mumaindasitiri uye masero emafuta.Zvisinei, mutengo mukuru uye kushomeka kwenoblemetal catalysts inoramba iine matambudziko makuru ekukura kwavo.Tsvagiridzo yeramangwana inoda kutarisisa pane synthesis nzira optimization, kuvandudzwa kwekuita, kudzikisa mutengo uye kusimba kwenoblemetal catalysts kukurudzira kushandiswa kwakakura kwenoblemetal catalysts mumunda wekubvisa kabhoni monoxide.
