Abstract:
A test was conducted to product activated alumina with aluminum chloride solution as feedstock. The reaction mechanism and suitable conditions of activated alumina production by spray pyrolysis had been analyzed. The calculation results showed that the standard Gibbs free energy of the pyrolysis reaction was far less than zero; through the analysis of AlCl3, H2O, HCl partial pressure, reaction degree could be controlled by the partial pressure of the gas phase. The physical characterization of Al2O3 was studied by XRD and SEM for different AlCl3 precursor concentration and reaction time on the reaction and optimized the synthesis conditions of activated alumina. It is therefore suggested that the combination of 15min and 15% was the best for activated alumina production, products mainly existed as ¦A- Al2O3 and particle size distribution was averageŁ¬the maximum specific surface area of the product surface area was 97.52m2/g.
