摘　　要：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 CO2 capture,and the capability of CaO calcined at 1000 K·s-1 was 15% higher than that calcined at 1 K·s-1 determined by TGA.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 CO2 capture, and the capability of CaO calcined at 1000 K · s^-1 was 15% higher than that calcined at 1 K ·s^-1 determined by TGA.
