Inkxaso ye-alpha alumina catalyst

Inkcazelo emfutshane:

I-α-Al2O3 yinto ene-porous, ehlala isetyenziselwa ukuxhasa i-catalysts, i-adsorbents, izinto zokuhlukana kwesigaba segesi, njl njl. I-α-Al2O3 yinqanaba elizinzile kunazo zonke ze-alumina kwaye ngokuqhelekileyo isetyenziselwa ukuxhasa amacandelo asebenzayo e-catalyst kunye nomlinganiselo ophezulu womsebenzi. Ubungakanani bepore ye-α-Al2O3 ye-catalyst carrier inkulu kakhulu kunendlela ye-molecular free, kwaye ukuhanjiswa kufana, ngoko ke ingxaki yokusasazwa kwangaphakathi ebangelwa ubungakanani obuncinci be-pore kwi-catalytic reaction system inokupheliswa ngcono, kunye neempendulo zecala le-oxidation enzulu zinokuncitshiswa kwinkqubo ngenjongo yokukhetha i-oxidation. Ngokomzekelo, i-catalyst yesilivere esetyenziselwa i-ethylene oxidation kwi-ethylene oxide isebenzisa i-α-Al2O3 njengomthwali. Ihlala isetyenziswa kwi-catalytic reactions kunye nobushushu obuphezulu kunye nolawulo lokusasazwa kwangaphandle.
