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.
