摘要: This work focuses on the influence of different parameters efficiency steel slag carbonation in slurry phase under ambient temperature. In first part, a response surface methodology was used to identify effect and interactions gas pressure, liquid/solid (L/S) ratio, gas/liquid ratio (G/L), reaction time CO2 removed/sample optimize parameters. second parameters' dissolution its conversion into carbonates were studied more detail. The results show that pressure G/L have positive both CO2. These been correlated with higher mass introduced reactor. On other hand, an important L/S overall removal specifically carbonate precipitation has identified. best obtained ratios 4:1 10:1 respectively 0.046 0.052 gCO2 carbonated/g sample. yields achieved after 10 min reaction, at temperature, 10.68 bar total following direct treatment.
