BACKGROUND. Phosphogypsum (PG) is a solid waste. For a fluidized bed, current research has focused on the preparation of CaO and SO 2 by PG decomposition, while less research has been conducted with calcium sulfide (CaS) as the target product. Therefore, the effect of different conditions on the preparation of CaS by coal reduction of PG was …
One of the common methods for reducing the metal particle size is optimizing the preparation method which aims to enhance the metal-support interaction, promote the dispersion of metal and decrease the metal reunion [24], [25].Recently, char-supported metal catalysts have attracted the attention of researchers not only because they are cheap and widely available but …
