This project investigates the feasibility that employing the fine powders (≤ 20 μm) as additives to further improve the fluidization ability of Group A powders. Three additives, Coal-15, GB-6, and SiO2-5 are added into FCC-76, based on various volume fractions. The minimum fluidization velocity (Umf), bed expansion ratio (BER), and dense phase expansion ratio (DER) are tested to evaluate the quality of fluidization. Coal-15 can slightly improve the fluidization quality. High content of GB-6 can make the mixture obtain some characteristics of Group C/A powders. While after adding 13.5% SiO2-5, BER and DER separately enhance 19.4% and 10.3%, besides, there is a 28.8% decrease in Umf. The improvement of Group A powders on the fluidization has potential industrial values, especially in improving the gas-solid reaction conversion.","abstract_html":"Group A powders are widely utilized in the industry because of the great quality of fluidization, which can be affected by the fine content.
