Kudziwa za cardrogenation catalysts

Mphamvu ya HydrogenationNdi zinthu zomwe zimakulitsa kuchuluka kwa hydrogenation Kuchita, zomwe zimaphatikizapo kuwonjezera ma atomu a hydrojeni ku molekyulu. Amagwiritsidwa ntchito kawirikawiri m'makampani a mankhwala ndi mafuta kuti asinthe ma hydrocarbons okwanira kuphatikizidwa ndi ma askssoms okhala ndi nickel, paldium, ndi platinic, yomwe nthawi zambiri imagwiritsidwa ntchito ngati zitsulo nanoparticles yothandizidwa ndi zinthu zodalirika. Kusankha kwa chothandizira kumadalira pa zomwe zimachitika, kuphatikizapo kutentha, kukakamizidwa, ndi ma anyakugwira ntchito. Ma caralysts amathanso kusinthidwa kudzera mu kugwiritsa ntchito olimbikitsa kapena ma ligands kuti athe kusintha ntchito yawo ndi kusankha kwawo. Kuphatikiza apo, hydrogenation zochita zimatha kuchitika pansi pa homogeneous kapena herdogeneints, kutengera kusungunuka kwa chothandizira mu zomwe mukuchita.

Njira ya hydrogenation imachitika njira zingapo zomwe zimaphatikizapo Adsorption wa asitikali a zokololazo pansi pa chothandizira, chotsatiridwa ndi kutsegula kwa mapangidwe a mgwirizano ndikupanga. Njira yeniyeni ya hydrogenation nthawi yomweyo imachitika pa catalytic pamwamba, zomwe zimapangitsa kuti kuwonjezera kwa maatomu a hydrogen kwa ochita. Zogulitsazo zimasankhidwa kuchokera pamwamba komanso zothandizira kuzungulira mobwerezabwereza.

Kugwiritsanso ntchito kwina kwa carrogeenation kukupanga hydrogen ngati mafuta. Izi zimadziwika kuti hydrogenation yamadzi, yomwe imaphatikizapo electrolysis yamadzi kuti itulutse haidrojeni ndi okosijeni. Munjira imeneyi, zothandizira zimagwiritsidwa ntchito kuyendetsa bwino zomwe zimachitika ndikuwonjezera mphamvu yake. Platinamu nthawi zambiri amagwiritsidwa ntchito ngati chothandizira pa izi chifukwa cha ntchito yake yayitali komanso kukhazikika.

M'zaka zaposachedwa, pakhala pali chidwi chochulukitsa othandizira mokhazikika padziko lapansi, zinthu zochuluka komanso zosakhala zoopsa, monga chitsulo ndi cobat, kuti muchepetse kudalira zamtengo wapatali pamilandu yamtengo wapatali. Zojambulazi zimakonzedwa pogwiritsa ntchito zida zapamwamba za masitepe, monga atomu-wosanjikiza mawonekedwe kapena mainjiniya.

Chonse,Mphamvu ya HydrogenationSewerani mbali yofunika kwambiri m'makampani ambiri komanso mafakitale, kulola kusintha kwa zinthu komanso kusankha mitundu yosiyanasiyana yopanga zinthu. Kuphatikiza apo pamakampani a petroleum, amagwiritsidwanso ntchito kapangidwe ka mankhwala abwino, mankhwala osokoneza bongo, ndi zowonjezera zowonjezera.
