| titleOfInvention | A kind of preparation method of high thermal stability modified aluminium oxide supports |
| abstract | The invention discloses a kind of method of preparing high thermal stability modified aluminium oxide supports, be characterized in using the aluminium ingot of purity >=99.5% and the lanthanide rare metal of purity >=99% according to mass fraction 10:1～200:1, in frequency induction melting furnace, melting obtains Al-La alloy cast ingot in a vacuum, ingot casting makes by pressure processing the strip that thickness is 0.05～0.5mm, cut into 1～50mm long, under the condition that the rectangle strip that 1～50mm is wide and isopropyl alcohol are catalyst at 1～5% aluminum trichloride (anhydrous), 85 ~ 95 DEG C of back flow reaction are after 4 ~ 8 hours, prepare aluminium isopropoxide and isopropyl alcohol group of the lanthanides metal dibasic alkoxide, this dibasic alkoxide is 60 ~ 80 DEG C of not exclusively hydrolysis, be decompressed to after 0.09～0.01MPa at 60 ~ 85 DEG C, through distillation, hydrolysate is 85 ~ 95 DEG C of oven dry, 800～900 DEG C of calcinings, finally prepare the metal-modified high thermal stability aluminum oxide carrier of lanthanide rare powder body material. |
