Abstract

Accelerated carbonation of BOF slag in an RPB is a viable method for CO₂ capture due to its high mass transfer rate. However, the process chemistry of carbonation of BOF slag is not well-determined due to their complex compositions. In this investigation, the quantitative X-ray diffraction was utilized to determine the mechanism of carbonation reaction in an RPB. Rietveld refinement, which aims to minimize the difference between the experimental and refined XRD patterns by a least-square procedure, is performed to quantify the crystallized mineral. In addition, changes of physico-chemical properties of BOF slags before and after carbonation were evaluated.
