Alpha alumina catalyst txhawb nqa

Lus piav qhia luv luv:

α-Al2O3 yog cov khoom ntxeem tau, uas feem ntau yog siv rau kev txhawb nqa catalysts, adsorbents, roj theem sib cais cov ntaub ntawv, thiab lwm yam. α-Al2O3 yog lub sijhawm ruaj khov tshaj plaws ntawm tag nrho cov alumina thiab feem ntau yog siv los txhawb cov catalyst active Cheebtsam nrog rau kev ua haujlwm siab. . Lub pore loj ntawm α-Al2O3 catalyst carrier yog loj dua li txoj kev tsis pub dawb molecular, thiab kev faib tawm yog ib yam, yog li qhov teeb meem sab hauv diffusion tshwm sim los ntawm qhov me me pore loj hauv cov tshuaj tiv thaiv catalytic tuaj yeem raug tshem tawm zoo dua, thiab sib sib zog nqus oxidation. Cov tshuaj tiv thaiv sab tuaj yeem txo qis hauv cov txheej txheem rau lub hom phiaj ntawm kev xaiv oxidation. Piv txwv li, cov nyiaj catalyst siv rau ethylene oxidation rau ethylene oxide siv α-Al2O3 ua tus cab kuj. Nws yog feem ntau siv hauv catalytic cov tshuaj tiv thaiv nrog kev kub siab thiab kev tswj hwm sab nraud.
