I-Hydrogenation catalystszizinto ezandisa umlinganiselo wokusabela kwehydrogenation, ezibandakanya ukongezwa kweeathom zehydrogen kwimolekyuli.Ziye zisetyenziswe ngokuqhelekileyo kumashishini ekhemikhali kunye nepetroleum ukuguqula i-hydrocarbons engaxutywanga kwiifom ezigcweleyo.Ii-hydrogenation catalysts eziqhelekileyo ziquka isinyithi ezifana ne-nickel, i-palladium, kunye ne-platinum, ehlala isetyenziswa ngendlela ye-nanoparticles yensimbi exhaswa kwizinto ezixhasayo.Ukukhethwa kwe-catalyst kuxhomekeke kwiimeko ezithile zokusabela, kubandakanywa ubushushu, uxinzelelo, kunye ne-reactants echaphazelekayo.Ii-catalysts nazo zinokuguqulwa ngokusetyenziswa kwabagqugquzeli okanye ii-ligands ukulungelelanisa umsebenzi wabo kunye nokukhetha.Ukongeza, iimpendulo ze-hydrogenation zinokuqhutywa phantsi kweemeko ezilinganayo okanye ezingafaniyo, kuxhomekeke kwi-solubility ye-catalyst kumxube wokuphendula.

I-mechanichan ye-hydrogenation reactions ngokuqhelekileyo yinkqubo yamanyathelo amaninzi ebandakanya i-adsorption ye-reactants kumphezulu we-catalyst, elandelwa kukusebenza kwee-reactants ngokuqhawula ibhondi kunye nokwakheka.Eyona mpendulo ye-hydrogenation emva koko yenzeke kumphezulu we-catalytic, ekhokelela ekongezweni kweeathom ze-hydrogen kwii-reactants.Iimveliso ke zihlanjululwa ukusuka kumphezulu kwaye umjikelo we-catalytic uyaphinda.

Olunye usetyenziso olubalulekileyo lwee-catalysts ze-hydrogenation kukuveliswa kwe-hydrogen njengamafutha.Oku kwaziwa ngokuba yi-hydrogenation yamanzi, ebandakanya ukuhlanjululwa kwamanzi ukuvelisa i-hydrogen kunye ne-oksijini.Kule nkqubo, i-catalysts isetyenziselwa ukuququzelela ukuphendula kunye nokwandisa ukusebenza kwayo.Iplatinam idla ngokusetyenziswa njengecatalyst yale reaction ngenxa yomsebenzi wayo ophezulu kunye nokuzinza.

Kwiminyaka yakutshanje, kuye kwakho ukwanda komdla ekuphuhliseni i-hydrogenation catalysts ezinzileyo esekelwe kubuninzi bomhlaba kunye nezinto ezingenayo ityhefu, ezifana nentsimbi kunye ne-cobalt, ukunciphisa ukuxhomekeka kwiintsimbi ezixabisekileyo.Ezi zincedisi zidla ngokulungiswa kusetyenziswa ubuchule bokudityaniswa kwemathiriyeli ephucukileyo, njengokubekwa kweathom-umaleko okanye ubunjineli bomphezulu.

Kuko konke,i-hydrogenation catalystsidlala indima ebalulekileyo kwiinkqubo ezininzi zeekhemikhali kunye nezoshishino, ezivumela ukuguqulwa okusebenzayo kunye nokukhethwa koluhlu olubanzi lweekhompawundi eziphilayo.Ukongeza ekusebenziseni kwabo kwishishini lepetroleum, zikwasetyenziselwa ukuhlanganiswa kweekhemikhali ezintle, amayeza, kunye nezongezo zokutya.Uphuhliso lwezixhobo ezisebenzayo nezizinzileyo ze-hydrogenation catalysts yintsimi eguquka ngokukhawuleza enamathuba amaninzi ophando kunye nokusetyenziswa kwindawo ebanzi. uluhlu lwamashishini.
