摘  要:Pseudo-boehmite (PB) and γ-Al2O3 support are prepared by neutralization ofNaAlO2 solution with CO2(mixed gases) on bench scale. PB, typically loosely packed, fibrous particle/aggregate, is obtained by adjustingconcentration and flow rate of CO2 and concentration of NaAlO2 solution at a pH level lower than that commonlyassumed during neutralization. After calcination at different temperatures, γ-Al2O3 supports with different pore vol-ume and different pore size are prepared at different conditions.Pseudo-boehmite (PB) and γ-Al_2O_3 support are prepared by neutralization ofNaAlO_2 solution with CO_2 (mixed gases) on bench scale.
