Preparation of calcium ferrite by flue gas

2021-3-5  The limestone-gypsum flue gas desulfurization process has been widely used in the current Chinese market. It uses limestone or lime slurry to absorb SO 2 in the flue gas to generate calcium sulfite, and the calcium sulfite is further oxidized to obtain calcium sulfate (CaSO 4) and finally recovered in the

Limestone calcination and

To develop a highly active calcium oxide high-temperature desulfurization sorbent, a method of preparation of macroporous calcium oxides from lime was studied. This method is composed of two steps: swelling of the lime and calcination of the swelled sample. Swelling occurred when lime was exposed to the vapor of acetic acid.
