Production of cementitious materials by flash

Pilot scale flash calciner. The pilot scale flash calciner (POLCAL-2) operates at TRL6 and can be used for thermal treatment of different materials e.g. calcination of carbonic materials (limestone, dolomite, phosphate ore) or activation of clays (kaolin, illite, etc.) or dehydroxilation of

Limestone Calcination with CO 2 Capture (II

2019-5-26 · Decomposition of limestone particles (0.25−0.5 mm) in a steam dilution atmosphere (20−100% steam in CO 2) was investigated by using a continuously operating fluidized bed reactor for CO 2 capture. The decomposition conversion of limestone increased as the steam dilution percentage in the CO 2 supply gas increased. At a bed temperature of 1193 K, the conversions were 72% without

CO2 Capture via Cyclic Calcination and Carbonation

2014-4-18 · Abstract. The reversible carbonation and calcination reactions of, respectively, CaO and CaCO 3 have very promising CO 2 capture characteristics with regard to CO 2 capture costs, theoretical CO 2 uptake per gram of sorbent and material availability. However, CaO derived from naturally occurring Ca-based materials, predominantly limestone, shows a rapid decrease in its CO 2 capture capacity
