Iziphi Izimboni I-Precious Metal Catalysts Esetshenziswayo?
Ama-catalyst ensimbi ayigugu adlala indima ebalulekile ezinqubweni zezimboni ngenxa yezakhiwo zawo eziyingqayizivele kanye nokuzinza. Ekucwengisweni kwe-petroleum, ziwukhiye wokuguqula i-catalytic, i-alkane ne-aromatic isomerization, kanye nokusabela kwe-dehydrogenation, okuthuthukisa kakhulu ukusebenza kahle kokusabela kanye nokukhetha komkhiqizo. Ekukhiqizeni i-olefin, zisetshenziselwa i-hydrogenation ekhethiwe, iqinisekisa ukuhlanzeka kanye nekhwalithi yemikhiqizo ye-olefin.
Ama-catalyst ensimbi ayigugu abaluleke ngokufanayo ekukhiqizeni izinto zokusetshenziswa zamakhemikhali emvelo. Ukukhiqizwa kwamakhemikhali abalulekile asetshenziswa njenge-ethylene oxide, i-acetaldehyde, ne-vinyl acetate konke kuncike esenzweni esinamandla sezinsimbi zensimbi eziyigugu. Lawa ma-catalyst awathuthukisi ukusebenza kahle kokukhiqiza kuphela kodwa futhi anciphisa izindleko zokukhiqiza, okuletha izinzuzo ezinkulu zezomnotho embonini yamakhemikhali.
Ukuvikelwa kwemvelo kungenye indawo enkulu yokufakwa kwezicelo zama-catalyst ensimbi eyigugu. Ekushisweni okunamandla kwamagesi emfucumfucu yezinto eziphilayo kanye ne-catalytic oxidation yamanzi angcolile ezimbonini, izisusa zensimbi eyigugu zinganciphisa ngempumelelo ukukhishwa kwamagesi ayingozi, zivikele imvelo. Isibonelo, ekuhlanzeni i-exhaust yezimoto, i-palladium ne-platinum catalysts ngezindlela ezintathu-iziguquli ze-catalytic ezingaguqula amagesi ayingozi abe izinto ezingenabungozi, okuthuthukisa kakhulu ikhwalithi yomoya.
Ngaphezu kwalokho, ama-catalyst ensimbi ayigugu aphinde abonise amandla amakhulu okusebenza endaweni entsha yamandla. Njengezinto ezibalulekile kumaseli e-hydrogen fuel kanye nemishini yokukhiqiza i-hydrogen ye-electrolysis yamanzi, ama-catalyst ensimbi eyigugu adlala indima ebalulekile ekuqhubekiseni ukuthuthukiswa kobuchwepheshe obusha bamandla.
Ezimbonini zemithi nezibulala-zinambuzane, ama-catalyst ensimbi ayigugu nawo asebenza kabanzi. Zisetshenziswa ekuhlanganiseni izidakamizwa namakha, kanye nokukhiqizwa kwezibulala-zinambuzane. Ama-catalysts e-Rhodium enza kahle kakhulu ekuhlanganisweni kwemithi, iphunga, kanye nezinto zokusetshenziswa zokusetshenziswa, kuyilapho ama-palladium catalysts asetshenziswa kakhulu ekuphenduleni kokuhlangana kwe-organic.
Emkhakheni wamakhemikhali amahle kanye nezinto ezintsha zamakhemikhali, izisusa zensimbi eyigugu nazo zinendima ebalulekile. Zisetshenziswa ekukhiqizeni i-liquid crystal intermediates, i-pigment, kanye nodayi, okuqhuba ukuthuthukiswa okusheshayo kwalezi zimboni. Ngesikhathi esifanayo, ngokuqwashisa kwemvelo okwandayo, kunesidingo esibalulekile sezinsimbi zensimbi eziyigugu emigqeni evikela imvelo kanye nokushintshwa kwama-catalyst akhona ngezinye izindlela ezihambisana nemvelo neziphephile.
