Kev txhawb nqa catalyst Alpha alumina

Kev Piav Qhia Luv:

α-Al2O3 yog ib yam khoom siv uas muaj qhov ntxeem tau, uas feem ntau siv los txhawb cov catalysts, adsorbents, cov khoom siv sib cais roj, thiab lwm yam. α-Al2O3 yog theem ruaj khov tshaj plaws ntawm txhua yam alumina thiab feem ntau yog siv los txhawb cov khoom siv catalyst nrog qhov sib piv siab. Qhov loj me ntawm α-Al2O3 catalyst carrier yog loj dua li txoj kev dawb molecular, thiab kev faib tawm yog sib xws, yog li qhov teeb meem diffusion sab hauv los ntawm qhov me me hauv qhov system catalytic reaction tuaj yeem tshem tawm zoo dua, thiab cov tshuaj tiv thaiv oxidation tob 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 feem ntau siv rau hauv catalytic reactions nrog qhov kub siab thiab kev tswj hwm diffusion sab nraud.
