Calcium hydride (CaH2) poda ikemikari yemakemikari yakawana kutarisisa kwayo kugona kwayo seye hydrogen kuchengetedza zvinhu. Nekuwedzera kutarisisa kwezvezvezve magetsi masosi uye kudiwa kwekuchengetedza simba kwakaringana, vaongorori vanga vachiongorora zvakasiyana siyana zvekugona kwavo kuchengeta uye kuburitsa hydrogen gasi. Calcium hydride yabuda semumiriri anovimbisa nekuda kwehurefu hwayo hwekuchengetera hydrogen uye yakanaka thermodynamic zvivakwa.
Imwe yemabhenefiti akakosha ecalcium hydride seye hydrogen yekuchengetera zvinhu ndeye yakakwira gravimetric hydrogen kugona, iyo inoreva huwandu hwehydrogen inogona kuchengetwa pachiyero cheuniti yezvinhu. Calcium hydride ine theoretical haidrojeni chengetedzo inokwana 7.6 wt%, ichiiita imwe yepamusoro-soro pakati pezvakasimba-state hydrogen kuchengetedza zvinhu. Izvi zvinoreva kuti zvishoma zvishoma zve calcium hydride powder inogona kuchengeta yakawanda yakawanda yehydrogen, ichiita kuti ive compact uye inobudirira yekuchengetedza sarudzo.
Uyezve, calcium hydride inoratidza yakanaka thermodynamic zvivakwa, zvichibvumira kudzoreredzwa kuchengetedza uye kuburitswa kwehydrogen gasi. Kana yakafumurwa kune hydrogen, calcium hydride inopinda kemikari inoita kuti igadzire calcium hydride hydride (CaH3), iyo inogona kuburitsa hydrogen pakupisa. Uku kugona kuchengetedza nekudzoreredza uye kuburitsa hydrogen kunoita kuti calcium hydride ive inoshanda uye inogoneka zvinhu zvekushandisa hydrogen kuchengetedza.
Pamusoro peiyo yakakwira hydrogen kuchengetedza uye yakanaka thermodynamic zvivakwa, calcium hydride zvakare yakawanda uye inodhura-inoshanda kana ichienzaniswa nezvimwe zvekuchengetedza haidrojeni. Izvi zvinoita kuti ive sarudzo inokwezva kune yakakura-yakakura mahydrogen ekuchengetedza masisitimu, kunyanya mumamiriro esimba rinodzokororwa uye tekinoroji yesero.
Nepo calcium hydride ichiratidza chivimbiso chikuru senge hydrogen yekuchengetera zvinhu, kuchine matambudziko anoda kugadziriswa, akadai sekuvandudza kinetics yehydrogen absorption uye desorption, pamwe nekusimudzira kugadzikana uye kusimba kwechinhu. Zvakadaro, kuenderera mberi kwekutsvagisa nekusimudzira kuedza kwakanangana nekukunda matambudziko aya uye kuvhura kugona kwakazara kwecalcium hydride sechinhu chinoshanda uye chinoshanda chekuchengetedza hydrogen.
Mukupedzisa, calcium hydride (CaH2) poda inobata mukana mukuru seye hydrogen kuchengetedza zvinhu, inopa yakakwirira hydrogen kuchengetedza simba, yakanaka thermodynamic zvivakwa, uye mutengo-kubudirira. Sezvo tsvakiridzo munharaunda iyi ichienderera mberi, calcium hydride inogona kuita basa rakakosha mukugonesa kutorwa kwehydrogen semutakuri wesimba wakachena uye wakasimba.
