Hydrogen (H2)

Technical parameters

Hydrogen muaj cov tshuaj formula H2 thiab molecular hnyav ntawm 2.01588. Nyob rau hauv ib txwm kub thiab siab, nws yog ib qho hluav taws kub heev, tsis muaj xim, pob tshab, tsis muaj ntxhiab thiab saj tsis muaj roj uas nyuaj rau yaj hauv dej, thiab tsis hnov ​​​​mob nrog ntau yam khoom. Txawm li cas los xij, nyob rau hauv qhov siab dua thiab kub kub, hydrogen reacts nrog ntau cov ntaub ntawv hydrocarbon hauv cov tshuaj tiv thaiv catalytic. Hydrogen yog cov roj tsawg tshaj plaws uas paub hauv ntiaj teb. Qhov ceev ntawm hydrogen tsuas yog 1/14 ntawm huab cua, uas yog, ntawm 1 tus qauv huab cua thiab 0 ° C, qhov ceev ntawm hydrogen yog 0.089g / L. Hydrogen yog cov khoom siv tseem ceeb hauv kev lag luam. Petroleum thiab tshuaj industries xav tau ib tug loj npaum li cas ntawm hydrogen. Ntawm lawv, kev ua cov fossil fuels thiab tsim cov ammonia los ntawm cov txheej txheem Hubble yog cov kev siv tseem ceeb. Ntxiv nrog rau kev siv tshuaj lom neeg, hydrogen kuj muaj ntau yam kev siv hauv physics thiab engineering. Nws tuaj yeem siv los ua cov roj tiv thaiv hauv qee txoj kev vuam. Hydrogen kuj yog ib qho tseem ceeb ntawm kev lag luam roj thiab roj tshwj xeeb, thiab nws muaj ntau yam kev siv hauv kev lag luam hluav taws xob, kev lag luam metallurgical, kev ua zaub mov, ntab iav, nplua organic synthesis, aerospace, thiab lwm yam. Nyob rau tib lub sijhawm, hydrogen kuj yog ib qho khoom siv zoo. Lub zog thib ob zoo tshaj plaws (lub zog thib ob yog hais txog lub zog uas yuav tsum tau tsim los ntawm lub zog tseem ceeb xws li hnub ci zog, thee, thiab lwm yam) thiab roj roj. Nws kub hnyiab raws li lub pob tshab nplaim, uas nyuaj rau pom. Dej yog tib yam khoom ntawm combustion. Hydrogen kuj tseem siv tau los ua cov khoom siv raw rau cov khoom siv hluavtaws ammonia, hluavtaws methanol, thiab hluavtaws hydrochloric acid, ua tus neeg sawv cev txo qis rau metallurgy, thiab ua tus neeg sawv cev hydrodesulfurization hauv roj av refining. Vim hais tias hydrogen yog ib qho hluav taws xob compressed roj, nws yuav tsum tau muab cia rau hauv qhov chaw txias, cua txias. Qhov kub hauv lub tsev yuav tsum tsis pub tshaj 30 ° C. Khaws kom deb ntawm qhov hluav taws kub thiab qhov chaw kub. Tsis txhob tshav ntuj ncaj qha. Nws yuav tsum tau muab cais tawm ntawm cov pa oxygen, compressed cua, halogens (fluorine, chlorine, bromine), oxidants, thiab lwm yam. Tsis txhob sib xyaw cia thiab kev thauj mus los. Lub teeb pom kev zoo, qhov cua thiab lwm yam khoom siv hauv chav cia khoom yuav tsum yog tawg-pov thawj, nrog cov keyboards nyob sab nraum lub tsev khaws khoom, thiab nruab nrog cov khoom sib xws thiab cov khoom siv tua hluav taws. Txwv tsis pub siv cov cuab yeej siv kho tshuab thiab cov cuab yeej uas ua rau muaj qhov tawg
