Development of CaO-Based Sorbent Doped with Framework Materials for CO2 Capture

Article Preview

Abstract:

Calcium looping technology is an attractive method for CO2 capture in dual fluidized bed combustion (FBC) reactors. The major limit for this technology is that the capture capacity of CaO-based sorbents sharply decreases with increasing cycle numbers. Attrition and consequent elutriation of CaO-based sorbents from FBC reactors also limit its application. In order to overcome these shortcomings, doping with framework materials is shown as a promising potential solution. Therefore, this work looks at a review of the CO2 capture capacities of CaO-based sorbents doped with different framework materials, such as aluminate cements, kaolin, aluminum oxides, magnesium oxide, titanium dioxide, and lanthanum salt. The synthetic sorbents have a better performance in CO2 capture capacities than the original sorbents in long term carbonation/calcination cycles.
