Hydrogenation waa hannaan kiimiko oo muhiim ah oo si ballaaran looga isticmaalo warshado kala duwan, oo ay ku jiraan kiimikooyinka batroolka, daawooyinka, iyo wax soo saarka cuntada. Udub-dhexaadka habkan waxaa ku jira kicinta hydrogenation-ka, walax soo dedejisa falcelinta ka dhaxaysa hydrogen iyo xeryahooda kale iyada oo aan la isticmaalin habka. Maqaalkani waxa uu si qoto dheer u falanqeynayaa muhiimada, noocyada, hababka, iyo codsiyada kicinta hydrogenation-ka, iyada oo siinaya faham dhamaystiran oo ku saabsan doorka ay ku leeyihiin kimistariga casriga ah.
## Waa maxay Hydrogenation?
Hydrogenation waa fal-celin kiimikaad oo ku lug leh ku-darka hydrogen (H₂) isku-dhisyada noolaha ee aan saturated ahayn, sida caadiga ah alkenes ama alkynes, si loogu beddelo hydrocarbons saturated. Habkani waxa uu lama huraan u yahay codsiyo kala duwan, sida saliidda khudradda oo loo beddelo margarine, soo saarista shidaal, iyo isku-darka dawooyinka.
Falcelinta guud waxa loo matalli karaa sida soo socota:
\[ \text{RCH=CHR'} + H_2 \xrightarrow{\text{Catalyst}} \text{RCH}_2\text{CH}_2\text{R'} \]
Isla'egtan, R iyo R' waxay u taagan yihiin silsiladaha hydrocarbon, kataliyuhuna wuxuu fududeeyaa isku darka hydrogen ee isku xidhka labanlaaban.
