中文摘要：
引言 化石能源消耗的不断增长，使得大气中温室气体浓度不断增加，由此导致的全球气候变化，特别是温室效应已成为人类生存不可忽视的问题。CO2是最主要的温室气体，削减CO2排放量、缓解温室效应，已成为国际社会的广泛共识。燃煤过程中的CO2排放占到我国CO2总排放的70％以上，研究针对燃煤烟气中CO2的处理技术对我国严格控制CO2排放有着重要意义。
英文摘要：
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.
