摘要:概述了 CaCO3 分解动力学的研究方法及进展,介绍了前期工作者关于 CaCO3 分解动力学的一些研究方法和
结论,以及由于研究方法、试验手段、反应条件和颗粒粒径等多方面因素的差异而导致反应速率控制机理的不同,
同时也介绍了 CaCO3 在悬浮状态下比较系统的研究结论,并指出了高固气比循环反应装置是下一步研究 CaCO3 分
解动力学的更为适宜的反应器。

Abstract: The research method and development of posed ics on calcium carbonate was
reviewed. Some methods and conclusions of p revious researcher were introduced on posed ics
of CaCO3. And control mechanism of reaction rate is different by diveristy of many aspect factors , for
examp le, research method, experiment measure, reaction condition and particle size , etc. Moreover, more
systematic study conlusions on CaCO3 were mentioned in suspension state, and it was refered that
circulating reaction equipment of high solid to gas ratio will be a kind of more suitable reactor for
posed ics of CaCO3.
Key words: posed ics; simulation; suspension state; review
