kev npaj
Txhua txoj kev npaj no muaj nws qhov zoo thiab qhov tsis zoo, thiab qhov kev xaiv ntawm txoj kev yog nyob ntawm cov khoom xws li cov khoom siv raw, cov nqi tsim khoom, cov khoom siv purity, thiab kev xav txog ib puag ncig. Tam sim no, cov txheej txheem Solvay thiab Hou cov txheej txheem yog cov txheej txheem kev lag luam siv dav tshaj plaws rau kev tsim khoom.
Qhov no yog ib qho ntawm cov laus tshaj plaws thiab feem ntau siv txoj kev tsim khoomsodium carbonate hmoov. Cov txheej txheem pib nrog kev sib cais ntawm cov ntsev ntau (NaCl) hauv dej, tom qab ntawd tshem tawm cov impurities xws li magnesium thiab calcium. Ammonia (NH3) yog tom qab ntawd nkag mus rau hauv cov dej ntshiab huv los ua ammonium chloride (NH4Cl). Cov pa roj carbon dioxide (CO2) tom qab ntawd dhau los ntawm cov brine ammonia, ua rau nag lossis daus ntawm sodium bicarbonate (NaHCO3). Tom qab pom thiab calcination ( cua sov kom decompose), cov khoom ntshiab yog tau. Cov cawv niam los ntawm cov txheej txheem no yog rov ua dua tshiab, nrog ammonia rov qab thiab rov siv dua.
Kuj tseem hu ua cov txheej txheem tsim khoom sib koom ua ke, txoj kev no tau tsim los ua kev txhim kho ntawm cov txheej txheem Solvay. Nws koom nrog kev nqus ntawm ammonia rau hauv cov tshuaj brine, ua raws li cov pa roj carbon monoxide ntawm no ammonia brine nrog CO2 los tsim sodium bicarbonate. Cov bicarbonate yog lim, calcined los tsim dej qab zib tshauv, thiab niam cawv yog rov ua dua. Tsis tas li ntawd, ammonium chloride yog crystallized tawm ntawm niam cawv thiab tuaj yeem ua tiav ntxiv los tsim cov ammonia, tsim kom muaj lub kaw - lub voj kaw. Cov txheej txheem no ua tau zoo dua ntawm kev siv cov peev txheej thiab txo cov pov tseg.
Qee qhov tso nyiaj ntawm cov khoom ntuj tsim, hu ua trona, tuaj yeem ua tiav ncaj qha los tsim cov dej qab ntsev. Qhov no suav nrog crushing cov ore, dissolving nyob rau hauv dej los yog cawv niam, thiab ces purifying cov tshuaj. Cov tshuaj purified yog tom qab ntawd carbonated, lim, thiab calcined los tsim. Cov txheej txheem sib txawv, xws li cov txheej txheem sesquicarbonate lossis cov txheej txheem monohydrate, yog siv nyob ntawm qhov zoo thiab muaj pes tsawg leeg ntawm trona ore.
Ib txoj kev tsis ntev los no muaj xws li carbonation ntawm cov dej qab zib caustic (muaj NaOH thiab Na2CO3) nrog CO2-muaj roj los hloov NaOH rau Na2CO3. Nyob ntawm seb muaj pes tsawg leeg ntawm cov cawv thiab cov khoom xav tau (anhydrous lossis monohydrate sodium carbonate), cov cawv carbonated yog tom qab ntawd ua tiav hauv theem crystallization nrog ntxiv caustic soda cawv ntawm ntau qhov sib txawv ntawm NaOH. Txoj kev no tso cai rau kev tsim tawm ntawm ob qho tib si anhydrous thiab monohydrate cov ntaub ntawv ntawm cov khoom nrog siab purity thiab efficiency.
Ntxiv nrog rau cov txheej txheem kev lag luam saum toj no, chav kuaj- nplai synthesis ntawm nws kuj tuaj yeem ua tiav los ntawm ntau yam tshuaj tiv thaiv, xws li cov tshuaj tiv thaiv ntawm sodium hydroxide nrog carbon dioxide los yog decomposition ntawm sodium bicarbonate. Txawm li cas los xij, cov txheej txheem no tsis haum rau loj - nplai kev lag luam vim lawv cov nqi thiab tsis muaj txiaj ntsig.
Ib qho kev tshawb fawb tseem ceeb uas cuam tshuam nrog cov khoom lag luam tsom rau nws daim ntawv thov hauv kev sib txuas ntawm zeolites, chav kawm ntawm cov ntxhia pob zeb crystalline nrog ntau cov ntawv thov kev lag luam. Cov kws tshawb fawb tau tshawb nrhiav kev siv los ua tus neeg sawv cev templateing thiab alkaline qhov chaw hauv hydrothermal synthesis ntawm zeolites.
Nyob rau hauv txoj kev tshawb no, nws tau tov nrog silica qhov chaw, xws li silica gel los yog mov husk tshauv, thiab dej los ua ib tug gel-zoo li precursor. Tom qab ntawd cov sib tov tau raug rau hydrothermal kev kho mob ntawm qhov kub thiab txias siab, tso cai rau nws mus rau catalyze lub tsim ntawm zeolite moj khaum.
Cov txiaj ntsig zeolites tau nthuav tawm cov porosity zoo heev, thaj chaw siab, thiab thermal stability, ua rau lawv tsim nyog rau kev siv xws li catalysis, gas sib cais, thiab ion pauv. Cov kev tshawb fawb tau qhia txog lub luag haujlwm hauv kev hloov kho zeolite cov qauv thiab cov khoom, ua kom muaj kev sib txuas ntawm cov zeolites nrog cov haujlwm tshwj xeeb.
Lwm qhov kev tshawb fawb piv txwv tau tshuaj xyuas kev siv hauv kev tsim cov eco- phooj ywg ua vaj tse. Los ntawm kev sib koom ua ke rau hauv cov pob zeb sib xyaw, cov kws tshawb fawb tau pom tias muaj kev ua haujlwm zoo dua qub, txo lub sijhawm teem sijhawm, thiab txhim kho kev ua haujlwm ntawm cov pob zeb. Nws ua raws li tus activator rau cov khoom siv pov tseg, xws li ya tshauv thiab slag, txhawb nqa lawv kev siv hauv cov qauv tsim ua vaj tse.
Cov kev tshawb fawb no qhia tau hais tias muaj ntau yam thiab muaj peev xwm ntawmsodium carbonate hmoovnyob rau hauv kev tsav tsheb innovation thiab sustainability nyob rau hauv ntau yam industrial sectors.
