Inkxaso ye-alpha alumina catalyst

Inkcazo emfutshane:

I-α-Al2O3 yinto enamaxolo, edla ngokusetyenziselwa ukuxhasa ii-catalysts, ii-adsorbents, izixhobo zokwahlula i-gas phase, njl. I-α-Al2O3 yeyona nqanaba lizinzileyo kuzo zonke i-alumina kwaye idla ngokusetyenziselwa ukuxhasa izinto ezisebenzayo ze-catalyst ezine-activity ratio ephezulu. Ubungakanani be-pore ye-α-Al2O3 catalyst carrier bukhulu kakhulu kunendlela ekhululekileyo ye-molecular, kwaye usasazo luyafana, ngoko ke ingxaki yokusasazwa kwangaphakathi ebangelwa bubungakanani be-pore encinci kwinkqubo ye-catalytic reaction inokupheliswa ngcono, kwaye iimpendulo ezinzulu ze-oxidation side zinokuncitshiswa kwinkqubo ngenjongo ye-oxidation ekhethiweyo. Umzekelo, i-catalyst yesilivere esetyenziselwa i-ethylene oxidation kwi-ethylene oxide isebenzisa i-α-Al2O3 njenge-catalyst. Ihlala isetyenziswa kwii-catalytic reactions ezinobushushu obuphezulu kunye nolawulo lwe-diffusion lwangaphandle.
