文摘
- •
The effect of reaction time, temperature and L/S ratio on conversion was evaluated.
- •
CO2 mass balance in slurry reactor was established with an error of less than 10%.
- •
Reaction kinetics and effective diffusivity for carbonation were determined by SCM.
- •
The maximum conversion was predicted by RSM via nonlinear mathematical programming.
- •
Applications and limitations of SCM and RSM for BOFS carbonation were illustrated.
