Uninzi lwe-hydrogenation catalyst ye-alumina catalyst carrier yokuqala ene-high ignition point, high melting point, nto leyo ebonisa ukuba luhlobo lwe-refractory oxide, nto leyo eyenza ukuba izinto ezincinci ze-catalyst ezincinci ezisasazeke kakhulu zahlulwe, ukuze kuthintelwe ukuhlanganiswa kwe-catalyst carrier okanye i-sintering okwesibini, i-alumina kwisigaba ikhona kuluhlu olubanzi lobushushu, kwaye yenza isakhiwo sayo sangaphakathi phantsi kobushushu obuphezulu xa ukulungiswa kwakhona kwekristale kuzinzile kubushushu obuphezulu, ukumelana nokuguguleka, ukusebenza okuhle kokudlulisa ubushushu ukongeza, ukubakho kwe-acidic kunye ne-alkaline center efana ne-acid reaction kumphezulu we-alkaline medium, kwaye enokusabela njenge-alkali kumphezulu we-acidic. Ngenxa ye-alumina catalyst ... bonisa ukuba i-alumina isebenza kakuhle kakhulu njengesithwali se-catalyst.
