Abstract:

A wire-mesh reactor capable of heating samples at a given heating-rate (1—1000 K•s^-1) was used to investigate the effect of heating-rate on Ca-based absorbent performance of CO₂ capture.BET method was used to analyze the morphology of the produced CaO, and the capabilities of the absorbent were compared.It was found that CaO calcined at a higher heating-rate had more appropriate pore distribution for CO₂ capture, and the capability of CaO calcined at 1000 K•s^-1was 15% higher than that calcined at 1 K•s^-1 determined by TGA.
