Ukusetyenziswa koMhlaba oRare ekuCocisweni kweGasoline Vehicle Exhaust

Ekupheleni kuka-2021, i-China inezithuthi ezingaphezu kwezigidi ezingama-300, apho izithuthi zepetroli zithatha ngaphezu kwe-90%, eyona nto ibalulekileyo e-China. Ukuze ujongane nongcoliseko oluqhelekileyo olufana nenitrogen oxides (NOx), i-hydrocarbons (HC) kunye ne-carbon monoxide (CO) kwi-exhaust yemoto yepetroli, "indlela-ntathu ye-catalyst", itekhnoloji yemoto yepetroli ebalaseleyo yokukhupha itekhnoloji, iye yaphuhliswa. , isetyenziswe kwaye iphuculwe ngokuqhubekayo. Itekhnoloji esandula ukuduma yepetroli kwi-cylinder direct injection (GDI) iya kukhokelela ekukhutshweni okubalulekileyo kwe-particulate pollutant (PM), ekhokelela ekuvelisweni kwetekhnoloji ye-petroli particulate filter (GPF). Ukuphunyezwa kobuchwephesha obungasentla kuxhomekeke ngaphezulu okanye ngaphantsi ekuthatheni inxaxheba kobutyebi bobuchule baseTshayina - umhlaba onqabileyo. Eli phepha kuqala liphonononga uphuhliso lwetekhnoloji yokucoca izithuthi zepetroli ezahlukeneyo, kwaye emva koko lihlalutya iindlela ezithile zesicelo kunye neziphumo zezinto ezinqabileyo zomhlaba (ingakumbi i-cerium dioxide) ngeendlela ezintathu zokugcina izinto zokugcina ioksijini, i-catalyst carrier / i-noble metal stabilizer kunye nemoto yepetroli. isihluzo senxalenye. Ingabonwa ukuba ngophuhliso kunye nokuphindaphindwa kwetekhnoloji yezinto ezintsha zomhlaba ezinqabileyo, itekhnoloji yokucoca isithuthi sepetroli yanamhlanje iya isebenza ngakumbi kwaye ingabizi kakhulu. Okokugqibela, eli phepha lijonge phambili kwindlela yophuhliso lwezixhobo zomhlaba ezinqabileyo zokucocwa kombhobho wepetroli, kwaye lihlalutya ezona ngongoma zibalulekileyo nezinzima zokuphuculwa kwekamva lamashishini anxulumeneyo.

Ijenali ye-China Rare Earth, yapapashwa okokuqala kwi-intanethi: ngoFebruwari 2023
