Cov ntaub ntawv kabmob alumina yog cov hmoov av dawb los yog alumina. Nws yog feem ntau thiab txais tos cov catalyst cab kuj . dab tsi yog nws daim ntawv thov?
Ua ntej, Nws thauj khoom catalytically tivthaiv.
1. Alumina nrog ib qho chaw me me (los yog tsuas yog ib qho me me ntawm cov khoom siv ntxim khoom) feem ntau yog siv los thauj khoom ntau yam khoom ua kom zoo. Lub hauv paus ntsiab lus yog tias kev siv cov kev lag luam uas ua rau alumina no muaj peev xwm tshem tawm cov teebmeem hauv qhov tob, hauv qhov txheej txheem ntawm oxidation selective, nws tuaj yeem txo qhov tob ntawm oxidation sab tshua,
2. Cov kab mob uas ua rau alumina ua rau thaj chaw loj loj muaj cov qauv zoo tsim, uas muaj peev xwm kis tau ntawm cov khoom txhawb nqa los ntawm cov khoom nplua zoo, thiab tiv thaiv cov sintering ntawm cov khoom tiv thaiv thaum siv los ntawm txoj kev siv Barrier nyhuv ntawm cov cab kuj. Nws yog siv cov dav hlau alumina.
Thib ob, qhov saum npoo ntawm cov kab mob dhia alumina thiab cov yam khoom txhawb lub zog yog tshwm sim los ua ib qho kev sib koom ua ke.
Piv txwv, platinum-alumina catalyst siv platinum txhim kho, uas alumina ua raws li ob qho tib si thiab kev tivthaiv ntawm cov catalyst, ntawm chav kawm, qee zaum muaj kev sib raug zoo ntawm kev txhawb alumina thiab xa cov hlau zoo xws li raws li platinum. Cov kev sib tshuam yuav cuam tshuam rau cov khoom siv hlau ntawm cov hlau.
Txij li thaum lub dav hlau alumina kuj muaj cov khoom sib txawv, xws li ntom ntom, pore qauv, ib thaj chaw, thiab lwm yam., Txawm tias nws yog tib daim ntawv, tab sis nws siv ntau yam.
