Abstract

Geldart Group A powders are utilized in various industrial processes because of their good fluidization quality, which is closely related to fine content (≤ 45 μm). This work systematically investigated the effect of fine powders (≤ 20 μm) as additives on the fluidization quality of Group A powders. Three types of additives, Coal-15, GB-6, and SiO₂-5 were added into the base powder FCC-76 (Group A) in various volume fractions. Among them, the addition of SiO₂-5 showed a significant improvement on the fluidization quality of Group A powder, exhibiting lower minimum fluidization velocity and higher bed expansion, while the addition of Coal-15 slightly improved the fluidization quality. The addition of a high-volume fraction of GB-6 would turn Group A into Group C/A, exhibiting some fluidization characteristics of Group C particles. Overall, the fluidization advancement of Group A powders modulated by Group C additives has advantages for industrial processes, especially for gas-phase catalytic reactions.
