Izinto ezi-Rare Earth Catalytic

Igama elithi'Calyst 'lisetshenzisiwe kusukela ekuqaleni kwekhulu le-19, kepha laziwa kabanzi cishe iminyaka engama-30, cishe libuyele emuva ngawo-1970s lapho ukungcoliswa komoya nezinye izindaba zaba yinkinga. Ngaphambi kwalapho, idlale indima ebaluleke kakhulu ekujuleni kwezitshalo zamakhemikhali abantu abangakwazi ukuyibona, buthule kodwa ngokuqhubekayo amashumishumi eminyaka. Yinsika enkulu yemboni yamakhemikhali, futhi ngokutholwa kwama-catalysts amasha, imboni yamakhemikhali enkulu ayikakathuthukiswa kuze kube yilapho imboni yezinto ezihlobene. Isibonelo, ukutholwa kanye nokusetshenziswa kwama-catalysts we-iron kwabeka isisekelo somkhakha wanamuhla wamakhemikhali, kuyilapho ukutholakala kwama-catalysts ase-Titanium asuselwa e-Petrochemical kanye ne-polymer syntheris. Eqinisweni, ukusetshenziswa kwalolo kwasekuqaleni kwezinto zomhlaba ezingavamile nakho kwaqala ngama-catalysts. Ngo-1885, iWersbach, i-Wershen Bat ifakwe isixazululo se-nitric acid equkethe ama-99% tho2 kanye ne-1% CEO2 ku-asbestos ukwenza i-catalyst, eyayisetshenziswa embonini yezokukhiqiza ama-Steam Latshade.

Kamuva, ngokuthuthukiswa kobuchwepheshe bezimboni kanye nokujula kocwaningoimihlaba engavamile, kwatholakala ukuthi ngenxa yomphumela omuhle wokuvumelanisa phakathi komhlaba okungavamile nezinye izinto ze-catalytic zensimbi, izinto ezingandile zomhlaba ezenziwe ngazo azisebenzi kahle hhayi ukusebenza ngobudlova okuhle kuphela kanye nokuqina kobunoshi obukhulu. Baningi kakhulu kwizinsizakusebenza, eshibhile ngentengo, futhi zizinze kakhulu ekusebenzeni kwezinsimbi eziyigugu, futhi zibe amandla amasha enkundleni ye-catalytic. Njengamanje, ama-raper emhlabeni ama-carlysts asetshenziswe kabanzi emikhakheni ehlukahlukene efana nokuqhekeka kukaPetroleum, imboni yamakhemikhali, ukuhlanzwa kwe-autotive anyathi, kanye nokuhlanzwa kwegesi yemvelo. Ukusetshenziswa komhlaba ongavamile emkhakheni wezinto zokwenziwa kwe-catalytic kuphendula isabelo esikhulu. I-United States idla ingxenye enkulu yoMhlaba ongavamile eCatalysis, kanti iChina nayo idla inani elikhulu kule ndawo.

Izinto ze-Rare Earth Catalytic ziyaqhubeka zisetshenziswa kabanzi emikhakheni yendabuko efana ne-petroleum nezobunjiniyela bamakhemikhali. Ngokuthuthuzelwa kokuqwashisa ngemvelo kazwelonke, ikakhulukazi ngokusondela kwe-Beijing 2008 Olimpiki kanye neShanghai 2010 World Expo, okuhlanjululwa kwamafutha okuhlanza, nokuqedwa kwegesi ye-catalytic, kanye nokuqedwa kwegesi eguquguqukayo ye-organic watura, nakanjani kuzokhuphuka kakhulu.
