Abstract
Aim The superfine Al(OH)-3 particles were prepared from sodium aluminate and carbon dioxide by rotating packed bed technology
the carbonation time was investigated. Methods The influence of rotating speed
liquid volume flow rate
gas volume flow rate
the initial sodium aluminate concentration and the ratio of the gas flow to the liquid flow on the carbonation reaction time were experimentally studied. Results and Conclusion The results show that the carbonation reaction time can be shortened greatly by rotating packed bed technology.
