| Abstract: |
| Three types of aluminum ashes and three high-temperature solid-phase catalysts were selected as experimental materials. Effects of temperature, time and catalyst on removal efficiency of composite salts in aluminum ash under high temperature conditions were investigated to obtain the best conditions for efficient removal of composite salts in aluminum ash. The results show that: 1) Type A catalyst is more suitable for removal of composite salts in high-aluminum aluminum ash. 2) Type B catalyst is more suitable for removal of composite salt from high-aluminum aluminum ash and high-magnesium aluminum ash. 3) Type C catalyst is more suitable for removal of composite salt in high-silica aluminum ash and high-magnesium aluminum ash. Under the optimal conditions, composite salt in calcined aluminum ash has a high removal rate and low content, which can meet the requirements of most industrial use of alumina materials and is expected to be used as an industrial raw material or an alternative raw material. |
