Mea hoʻololi Catalytic

ʻEkolu ala catalystʻo ia ka mea hoʻomaʻemaʻe waho nui loa i hoʻokomo ʻia i lokoʻōnaehana hoʻopau kaʻa.Hoʻopili hope ʻia e ke kaʻina hana hoʻouhi kūikawā me ka metala a i ʻole ka ceramic ma ke ʻano he mea lawe, hana ponoʻī ʻia ka honua laha ʻole e hoʻopili ai i ka oxide ma ke ʻano he mea kōkua a me kahi mea liʻiliʻi o ka metala makamae.ʻAʻole kūpono kēia huahana no ka hōʻemi.

Ua hoʻohana piha ka catalyst i ka hopena hoʻohui o nā metala makamae a me ka couound oxide o ka honua, ma lalo o ka mana o ka Carbon Oxide (CO), Hydrocarbon (HC) a me Oxynitride (Nox) i loko o ke kinoea huelo o nā kaʻa i hoʻokahe ʻia a deoxidized.Ma kēia ala, hoʻololi ʻia nā mea haumia ʻekolu i Carbon Dioxide (CO2), H2O a me Nitrogen i mea pōʻino ʻole i ka lewa.

Ma hope o 100 mau hola o ka hoʻāʻo ʻelemakule wikiwiki i ka ʻoihana ʻenekinia kaʻa o ke Kulanui ʻo Tsinghua, ʻo ka helu hoʻololi fractional o CO, HC a me Nox he 96.3%, 94% a me 90.5% pakahi.ʻO ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa o ka catalyst he 235 ℃, 272 ℃ a me 230C ℃ i piʻi aʻe e 45 ℃, 53 ℃ a me 40 ℃ i kēlā me kēia, ke hoʻohālikelike ʻia me nā catalysts hou ma hope o ka hopena o ka ʻelemakule a me ka coefficient ʻelemakule he 1.2 e like me ia.Ma hope o ka hoʻāʻo ʻana ma nā kaʻa, ua hōʻike ʻia ua hoʻokō ʻo ia i ka EuⅡEmission Standard.

Me ka hoʻokō ʻana i ka Eu Ⅲ Emission Standard a me Eu Ⅳ Emission Standard ma Kina, ua hoʻonui ʻo Company i ka mea hoʻohui a hoʻomohala i kahi ʻano o nā catalysts hou me ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, ʻoi aku ka maikaʻi o ka hoʻololi ʻana a me ka index resistant kiʻekiʻe ma lalo o ka sintering a laila noi no ka National Patent. no ka mea hou.ʻO ka hoʻololi ʻana o nā ʻenekini e like me ka CCC+UCC a i ʻole UCC Program e hiki ai i ka mea hoʻohui o ke kinoea huelo ke hoʻokō i ka Eu Ⅲ Emission Standard a me EU Ⅳ Emission Standard.I ka makahiki 2006, ua nānā ʻia ka mea hoʻohui o ke kinoea huelo ma ke kikowaena nānā ʻana i ka maikaʻi o nā kaʻa a me nā cotents o CO, HC a me Nox he 1.0g/km, 0.6g/km a me 0.08g/km kēlā me kēia, i hui pū me Eu Ⅲ Kūlana hoʻokuʻu.
Ka nui o ka mea lawe hao:

Ka nui o ka lawe ʻana i ka ceramic:
