Hauv kev lag luam chem niaj hnub, catalysts yog cov ntaub ntawv tseem ceeb uas txhawb cov kev tshua muaj txiaj ntsig .Alumina catalystsUa lub luag haujlwm tseem ceeb hauv petrochemicals, kev tswj hwm ib puag ncig, tshuaj xyuas hluavtaws thiab tshuaj xyuas cov tshuaj lom neeg tseem ceeb thiab tshuaj xyuas lawv lub cev muaj tshuaj lom neeg
{. tus yam ntxwv ntawm alumina catalysts
• Thaj chaw thaj chaw tshwj xeeb: feem ntau 200-400 m² / g, muab cov chaw nquag muaj rau reactants.
• Cov qauv ntxeem tau: dav Pore Loj faib ({0}}}}}}}}}}}}}}} kev cawm ntawm cov khoom .
• Kev ua si saum npoo av: Cov nplaim nplua nuj nyob hauv cov pab pawg hydroxyl, thiab chaw tsim khoom siv hluav taws xob (xws li cov hlau uas muaj nqis, hloov hlau oxides) {}}
• Cov qauv zoo thermal: tus qauv tseem tuaj yeem ruaj khov raws li cov kev mob siab, haum rau ntau yam kub ntawm .
• Muaj zog txhua yam: muaj qhov zoo compression thiab hnav tsis kam, haum rau kev lag luam kev siv {}}
{{02. Daim ntawv thov ntawm alumina catalyststs rau cov neeg siv tshuaj
1. Petrochemicals
• CATALYtic CRACKING: Hloov cov roj hnyav rau hauv cov roj kom nce ntau lawm cov roj av thiab diesel .
• HYROTREING: Tshem cov leej faj, nitrogen thiab lwm yam impurities hauv roj av los txhim kho cov roj zoo .
• Desulfurization: txo cov kab mob Sulfur hauv roj los ntawm catalytic cov tshuaj tiv thaiv los txo ib puag ncig kev muaj kuab paug .
2. ib puag ncig kev tswj hwm
• Catalytic Combusion: Siv los kho cov txiv organic cov tebchaw (vocs) hauv kev ua kom muaj zog roj carbon dioxide thiab dej .
• Khib roj carimy: tshem tawm cov tshuaj oxides (NOx) thiab sulfur oxides (sox) kom txo cov pa phem {}}
3.} Kev Tshuaj Ntsuam Xyuas Tshuaj Synthesis
• Alkration: Qhia cov pab pawg Alkyl rau cov khoom siv hauv organic los ua ke cov khoom siv siab ntxiv-ntxiv cov tshuaj.
• Isomerization: Hloov cov qauv molecular los txhim kho cov khoom lag luam thiab cov khoom zoo.
• Cov tshuaj tiv thaiv lub cev qhuav dej: siv los ua dej cawv qhuav los tsim cov olefins, uas yog ib kauj ruam tseem ceeb hauv kev siv roj hmab thiab cov pa roj hmab thiab cov roj ntsha {}}
{{0 {}} lub zog teb
• Roj hlwb: ua cov cab kuj catalyst, nws txhim kho cov efficiency thiab stability ntawm roj hlwb .
• Kev ua haujlwm hydrogen: Nws yog siv rau dej-hloov cov tshuaj tiv thaiv thiab hloov kho methohaning hloov kho los ua cov high-purity hydrogen .
Nyob rau hauv xyoo tas los no, cov kws tshawb nrhiav tau cog lus los tsim kev ua haujlwm tshiab alumina los txhim kho cov khoom siv catalysts thiab cov khoom siv sib txawv kom tau raws li cov kev xav tau ntawm cov kev xav tau sib txawv; Txhim kho qhov kev ua ub no thiab xaiv tau ntawm catalysts los ntawm kev thau cov khoom muaj nqis los yog cov nyom hlau oxides; Kev tsim cov txheej txheem ib puag ncig cov kev ua phooj ywg catalytic los txo cov hnoos qeev thiab kev siv hluav taws xob, thiab lwm yam}
Alumina catalysts yog hu ua "accelerators"} kev tswj hwm cov qauv ntawm cov chaw kawm tsis tu ncua thiab kev ua haujlwm zoo nkauj, kev ua haujlwm ntawm alumina catalysts yuav txuas ntxiv mus optimized thiab lawv cov ntawv thov yuav nthuav ntxiv {2} Nrhiav rau yav tom ntej, los ntawm kev tiv thaiv cov tshuaj ntsuab thiab muaj kev tiv thaiv ib puag ncig {}}
