I-Hydrogenation catalystsyizinto ezandisa izinga lokusabela kwe-hydrogenation, okuhlanganisa ukufakwa kwama-athomu e-hydrogen ku-molecule.Zivame ukusetshenziswa ezimbonini zamakhemikhali kanye ne-petroleum ukuguqula ama-hydrocarbons angasetshenzisiwe abe amafomu agcwele kakhulu.I-catalysts evamile ye-hydrogenation ihlanganisa izinsimbi ezifana ne-nickel, i-palladium, ne-platinum, evame ukusetshenziswa ngendlela ye-nanoparticles yensimbi esekelwe ezintweni ezisekelayo eziqinile.Ukukhethwa kwe-catalyst kuncike ezimweni ezithile zokusabela, okuhlanganisa izinga lokushisa, ingcindezi, nama-reactants ahilelekile.Ama-catalyst angabuye ashintshwe ngokusebenzisa abathuthukisi noma ama-ligand ukuze ashunise umsebenzi wabo nokukhetha.Ngaphezu kwalokho, ukusabela kwe-hydrogenation kungenziwa ngaphansi kwezimo ezilinganayo noma ezihlukahlukene, kuye ngokuthi ukuncibilika kwe-catalyst kungxube yokusabela.

Indlela yokusabela kwe-hydrogenation imvamisa iyisinyathelo esinezinyathelo eziningi esibandakanya ukukhangiswa kwama-reactants ebusweni be-catalyst, okulandelwa ukwenza kusebenze ama-reactants ngokuphuka kwebhondi kanye nokwakheka.Ukusabela kwangempela kwe-hydrogenation kube sekwenzeka endaweni eyi-catalytic, okuholela ekwengezweni kwama-athomu e-hydrogen kuma-reactants.Imikhiqizo ibe isikhishwa phezulu futhi umjikelezo we-catalytic uyaphinda.

Okunye okubalulekile okusetshenziselwa ama-catalysts e-hydrogenation ukukhiqizwa kwe-hydrogen njengophethiloli.Lokhu kwaziwa ngokuthi yi-hydrogenation yamanzi, okubandakanya i-electrolysis yamanzi ukukhiqiza i-hydrogen nomoya-mpilo.Kule nqubo, ama-catalysts asetshenziselwa ukwenza lula ukusabela nokwandisa ukusebenza kahle kwawo.I-Platinum ivame ukusetshenziswa njenge-catalyst yalokhu kusabela ngenxa yokusebenza kwayo okuphezulu nokuzinza.

Eminyakeni yamuva nje, kuye kwaba nentshisekelo eyengeziwe ekuthuthukiseni ama-catalysts e-hydrogenation asekelwe ezintweni ezinobuningi bomhlaba nezingezona ubuthi, njenge-iron ne-cobalt, ukunciphisa ukuthembela ezinsimbi eziyigugu.Lawa ma-catalyst ngokuvamile alungiswa kusetshenziswa amasu athuthukisiwe okuhlanganiswa kwezinto, njengokubeka ungqimba lwe-athomu noma ubunjiniyela bangaphezulu.

Sekukonke,i-hydrogenation catalystsidlala indima ebalulekile ezinqubweni eziningi zamakhemikhali nezezimboni, okuvumela uguquko olusebenzayo nolukhethayo lwenhlanganisela ebanzi yezinto eziphilayo.Ngaphezu kokusetshenziswa kwazo embonini ye-petroleum, ziphinde zisetshenziswe ekuhlanganiseni amakhemikhali amahle, imithi, kanye nezithasiselo zokudla.Ukuthuthukiswa kwama-catalysts e-hydrogenation asebenzayo futhi asimeme kuyinkambu ethuthuka ngokushesha enamathuba amaningi okucwaninga athakazelisayo kanye nezicelo endaweni ebanzi. uhla lwezimboni.
