I-calcium hydride (CaH2) powder iyinhlanganisela yamakhemikhali eye yaqaphela amandla ayo njengempahla yokugcina i-hydrogen. Ngokugxila okwandayo emithonjeni yamandla avuselelekayo kanye nesidingo sokugcinwa kwamandla ngendlela efanele, abacwaningi bebehlola izinto ezihlukahlukene ukuze bakwazi ukugcina nokukhulula igesi ye-hydrogen. I-calcium hydride iqhamuke njengekhandidethi ethembisayo ngenxa yomthamo wayo omkhulu wokugcina i-hydrogen kanye nezakhiwo ezithandekayo ze-thermodynamic.
Enye yezinzuzo ezibalulekile ze-calcium hydride njengento yokugcina i-hydrogen amandla ayo aphezulu e-gravimetric hydrogen, okubhekisela enanini le-hydrogen elingagcinwa ngeyunithi ngayinye yesisindo. I-Calcium hydride inamandla okugcina i-hydrogen angu-7.6 wt%, okuyenza ibe phezulu kakhulu phakathi kwezinto ezigcina i-hydrogen eziqinile. Lokhu kusho ukuthi inani elincane le-calcium hydride powder lingagcina inani elikhulu le-hydrogen, okwenza kube inketho yokugcina ehlangene futhi ephumelelayo.
Ngaphezu kwalokho, i-calcium hydride ikhombisa izakhiwo ezinhle ze-thermodynamic, evumela ukugcinwa okubuyiselekayo nokukhishwa kwegesi ye-hydrogen. Uma ichayeke ku-hydrogen, i-calcium hydride ibhekana nokusabela kwamakhemikhali ukuze yakhe i-calcium hydride hydride (CaH3), engakhulula i-hydrogen lapho ishisa. Leli khono lokugcina ngokubuyisela emuva futhi likhiphe i-hydrogen lenza i-calcium hydride ibe into esebenzayo neguquguqukayo yezinhlelo zokusebenza zokugcina i-hydrogen.
Ngaphezu komthamo wayo omkhulu wokugcina i-hydrogen kanye nezakhiwo ezithandekayo ze-thermodynamic, i-calcium hydride nayo iyindala futhi iyabiza uma iqhathaniswa nezinye izinto zokugcina i-hydrogen. Lokhu kuyenza ibe inketho ekhangayo kumasistimu amakhulu okugcina i-hydrogen, ikakhulukazi kumongo wamandla avuselelekayo kanye nobuchwepheshe bamaseli kaphethiloli.
Nakuba i-calcium hydride ibonisa isithembiso esihle njengento yokugcina i-hydrogen, kusenezinselelo ezisadinga ukubhekwana nazo, njengokuthuthukisa i-kinetics yokumuncwa kwe-hydrogen kanye ne-desorption, kanye nokuthuthukisa ukuqina nokuqina kwempahla. Noma kunjalo, imizamo eqhubekayo yocwaningo nentuthuko igxile ekunqobeni lezi zinselele nasekuvuleni amandla aphelele e-calcium hydride njengento esebenzayo nephumelelayo yokugcina i-hydrogen.
Sengiphetha, i-calcium hydride (CaH2) powder inamandla amakhulu njengempahla yokugcina i-hydrogen, enikeza amandla okugcina i-hydrogen aphezulu, izakhiwo ezithandekayo ze-thermodynamic, nokusebenza kahle kwezindleko. Njengoba ucwaningo kulo mkhakha luqhubeka nokuthuthuka, i-calcium hydride ingase ibambe iqhaza elibalulekile ekuvumeleni ukwamukelwa okusabalele kwe-hydrogen njengesithwali samandla esihlanzekile nesimeme.
