Ib txwm niaj hnub ammonia - tsim tawm cog thawj zaug hloov cov pa roj carbon monoxide (piv txwv li, methane) lossis LPG (liquefied petroleum gases xws li propane thiab butane) los yog roj av naphtha rau gaseous hydrogen. Tom qab ntawd cov hydrogen yog sib xyaw nrog nitrogen rau tsim ammonia los ntawm cov txheej txheem Haber-Bosch.
Tsuas yog li ntawd, yuav ua li cas Ammonia tsim?
Cov txheej txheem Haber muab cov nitrogen los ntawm huab cua nrog hydrogen muab los ntawm cov pa roj (methane) rau hauv ammonia . Cov tshuaj tiv thaiv yog reversible thiab ntau lawm ntawm ammonia yog exothermic. Lub catalyst yog qhov tseeb me ntsis nyuab dua li cov hlau ntshiab.
Kuj Paub, pes tsawg ammonia raug tsim tawm ib xyoos twg? Raws li tsis ntev los no li 80 xyoo dhau los, tag nrho kev tsim khoom txhua xyoo ntawm synthesized ammonia tsuas yog 300,000 m.t. Ua tsaug rau chemical engineering breakthroughs, ib qho niaj hnub ammonia cog tuaj yeem tsim ntau tshaj 750,000 m.t./yr. Kwv yees li 88% ntawm ammonia ua txhua xyoo yog siv nyob rau hauv kev tsim cov chiv.
Kuj paub, dab tsi yog ammonia synthesis?
Ammonia yog industrially npaj los ntawm cov txheej txheem Haber, ib txoj kev tshuaj uas siv nitrogen gas thiab hydrogen gas rau synthesize ammonia . Xwb, yog tias oxygen pom nyob rau hauv cov huab cua yog reacted nrog natural gas, nitrogen uas tseem unreacted yuav muab cais.
Yuav ua li cas ua hydrogen los ntawm ammonia?
Hydrogen tuaj yeem muab rho tawm los ntawm ammonia , ua ntej los ntawm kev siv lub catalyst los pab decompose lub ammonia molecule nyob rau hauv ib tug sib tov ntawm nitrogen thiab hydrogen gas. Ces, lub hydrogen membrane tso cai hydrogen kom hla dhau nws thaum thaiv lwm yam roj.

Yuav ua li cas ammonia thauj mus rau daim siab los ntawm piv txwv li cov leeg?
Qhov tsis muaj tshuaj lom cia thiab thauj daim ntawv ntawm ammonia hauv daim siab yog glutamine. Ammonia yog loaded ntawm glutamine synthetase los ntawm cov tshuaj tiv thaiv, NH3 + glutamate → glutamine. Nws tshwm sim nyob rau hauv yuav luag tag nrho cov ntaub so ntswg ntawm lub cev. Ammonia raug tshem tawm ntawm glutaminase los ntawm cov tshuaj tiv thaiv, glutamine --> NH3 + glutamate
Yuav ua li cas ammonia ua los ntawm natural gas?
Ib tsob nroj uas niaj hnub tsim cov ammonia ua ntej hloov cov pa roj (piv txwv li, methane) lossis LPG (liquefied petroleum gases xws li propane thiab butane) lossis roj av naphtha rau hauv cov pa roj hydrogen. Tom qab ntawd cov hydrogen tau ua ke nrog nitrogen los tsim cov ammonia ntawm Haber-Bosch txheej txheem
Yuav ua li cas compound yuav tsim yog Aluminium thiab oxygen tau ua ke?
Aluminium tuaj yeem hnov mob nrog cov pa oxygen los tsim cov txhuas oxide (Al_2O_3)
Yuav ua li cas muaj pes tsawg tus tooj liab atoms koj yuav tsum tau kab ntawm ib sab los tsim ib kab 1'm ntev?
Los ntawm kev sib piv, lub ntiaj teb cov pej xeem tsuas yog hais txog 7? 109 neeg. Yog tias koj tuaj yeem ua kab 100,000,000 tooj liab atoms ib sab, lawv yuav tsim ib txoj kab ntev li 1 cm
Yuav ua li cas yuav tsum tshwm sim rau electrons los tsim spectral kab?
Thaum cov electrons txav los ntawm qib siab zog mus rau qis dua, photons raug tso tawm, thiab cov kab hluav taws xob tuaj yeem pom hauv spectrum. Cov kab nqus tau pom thaum electrons nqus photons thiab txav mus rau qib siab zog. Yog hais tias lub atom tau poob ib los yog ntau dua electrons, nws yog hu ua ion thiab hais tias yuav ionized
