Kākoʻo ʻo Alpha alumina catalyst

ʻO ka wehewehe pōkole:

ʻO ka α-Al2O3 kahi mea porous, i hoʻohana pinepine ʻia no ke kākoʻo ʻana i nā catalysts, adsorbents, gas phase separation material, etc. . ʻOi aku ka nui o ka pore o ka α-Al2O3 catalyst carrier ma mua o ka molecular free ala, a ʻo ka hoʻohele like ʻana, no laila hiki ke hoʻopau maikaʻi ʻia ka pilikia diffusion kūloko ma muli o ka liʻiliʻi liʻiliʻi o ka ʻōnaehana catalytic reaction, a me ka hohonu o ka oxidation. hiki ke hoemi 'aoʻao reactions i loko o ke kaʻina hana no ke kumu o ka koho oxidation. No ka laʻana, hoʻohana ka catalyst kālā no ka ethylene oxidation i ka ethylene oxide i ka α-Al2O3 ma ke ʻano he mea lawe. Hoʻohana pinepine ʻia i nā hopena catalytic me ka wela kiʻekiʻe a me ka mana diffusion waho.
