| Abstract: | Conventional oven drying (COD) and supercritical drying (SCD) methods were applied to the preparation of Mn-substituted hexaaluminate
(BaMnAl11O19-α) catalysts. The effect of drying methods on phase composition, specific surface area, pore structure and combustion activity
of the samples was investigated. The samples obtained by SCD have higher surface area, narrower pore size distribution, and
higher combustion activity than those obtained by COD.
