The primary particle size of the CaCO 3 also gradually increased with an increase of the CO 2 flow rate at a low Ca(OH) 2 concentration, but the tendency became weak at high Ca(OH) 2 concentration. They also revealed that the CO 2 bubble size also affected the particle size and specific surface area (Bang et al., 2015). Conclusion

Overall, the optimum particle size in pilot plants based on fluidised bed reactors has been found to lie within the 100–300 µm range [46], [47]. Despite its importance, the influence of particle size in CaL-CSP has yet to be explored in sufficient detail since most published works use material with very wide particle size distributions.
