Alpha alumina catalyst rutsigiro

Tsanangudzo Pfupi

α-Al2O3 chinhu chine porous, chinowanzoshandiswa kutsigira catalysts, adsorbents, gas phase separation materials, etc. α-Al2O3 ndiyo inonyanya kugadzikana chikamu chealumina yose uye inowanzoshandiswa kutsigira catalyst active components ine high activity ratio. Saizi yepore ye α-Al2O3 inotakura inotakura yakakura kupfuura iyo molecular yemahara nzira, uye kugovera kwakafanana, saka dambudziko remukati rekupararira rinokonzerwa nekukura kwepore mu catalytic reaction system inogona kubviswa zvirinani, uye yakadzika oxidation mativi maitiro anogona kudzikiswa mukuita chinangwa chekusarudza oxidation. Semuenzaniso, iyo silver catalyst inoshandiswa kune ethylene oxidation kune ethylene oxide inoshandisa α-Al2O3 semutakuri. Inowanzo shandiswa mukukonzeresa maitiro ane tembiricha yepamusoro uye yekunze diffusion control.
