Isiguquli seCatalytic

Intshayelelo yale mveliso:

Yethuindlela ezintathu catalystIimoto zisebenzisa isinyithi okanye i-ceramic njengomthwali, yongeza i-oksidi eyenziwe ngokwakho enqabileyo yomhlaba njengesithako sesixhobo kunye nesixa esincinci sesinyithi esixabisekileyo, ke ekugqibeleni sintered emva kwenkqubo ekhethekileyo yokwambathisa.Le mveliso ayilahlwanga ekunciphiseni.

I-catalyst isebenzise ngokupheleleyo isiphumo sokulungelelaniswa kweentsimbi ezixabisekileyo kunye ne-rare-earth coupound oxide, phantsi kwempembelelo apho i-Carbon Oxide (CO), i-Hydrocarbon (HC) kunye ne-Oxynitride (i-Nox) kwi-gas yomsila we-autos i-oxidized kwaye yenziwe i-deoxidized.Ngale ndlela, ezi zingcolisi zintathu ziguqulwa zibe yiCarbon Dioxide(CO2), H2O kunye neNitrogen engenabungozi emoyeni.

Emva kweeyure ze-100 zebhentshi yokuvavanya ukuguga ngokukhawuleza kwisebe lobunjineli beemoto kwiYunivesithi yaseTsinghua, izinga lokuguqulwa kwe-fractional ye-CO, i-HC kunye ne-Nox yi-96.3%, i-94% kunye ne-90.5% ngokulandelanayo.Awona maqondo obushushu okuqala asezantsi e-catalyst yi-235℃, 272℃ kunye ne-230C℃ enyuke nge-45℃, 53℃ kunye ne-40℃ ngokulandelelanayo, xa kuthelekiswa nezinto ezintsha ezibangela ukuguga kunye ne-coefficient yokuguga yi-1.2 ngokufanelekileyo.Emva kokuvavanywa kwiimoto, kwabonakala ukuba idibene ne-EuⅡEmission Standard.

Ngokunyanzeliswa koMgangatho we-Eu Ⅲ wokuMisela kunye ne-Eu Ⅳ uMgangatho wokuKhusela e-China, iNkampani iye yaphucula isithako yaza yaphuhlisa uthotho lwezinto ezintsha ezinobushushu obuphantsi bokutshisa, uguqulo olusulungekileyo kunye nesalathiso esixhathisayo esiphakamileyo phantsi kwe-sintering emva koko yafaka isicelo sePatent yeSizwe. yokuqanjwa.Uhlengahlengiso lweenjini ngokweCCC+UCC okanye iNkqubo ye-UCC yenza ukuba isithako serhasi yomsila ihlangabezane ne-Eu Ⅲ uMgangatho wokuThunyelwa kunye ne-EU Ⅳ uMgangatho wokuKhawulwa.Kwi-2006, isithako segesi yomsila yahlolwa kwiziko lokuhlola umgangatho wesizwe weemoto kunye ne-cotents ye-CO, i-HC kunye ne-Nox yayiyi-1.0g/km, 0.6g/km kunye ne-0.08g/km ngokulandelanayo, eyayidibene ne-Eu Ⅲ. Umgangatho wokuPhuma.
