Modified aluminas and the use thereof in FCC catalysts. |
| 摘要 |
<p>A modified alumina and its use as metals passivator in fluidisable catalytic cracking catalysts. The modified alumina is prepared from a hydrated alumina, e.g., gibbsite, which is reacted with a low-molecular weight organic acid, e.g., acetic acid, forming aluminium salt. Calcination of the modified alumina results in decomposition of the aluminium salt. <IMAGE></p> |
