钙基吸收剂脱硫反应特性的研究

Study on Desulfurization Reaction Characteristic of Calcium Based Sorbents

本文对两种钙基吸收剂——ＣａＯ和Ｃａ（ＯＨ）２的脱硫反应机理进行了试验研究。对两者的反应活性进行了比较，并就一些因素（包括吸收剂粒径、脱硫反应温度、Ｆｅ２Ｏ３、ＮａＣｌ、Ｖ２Ｏ５和ＺｎＯ等添加剂等）对脱硫活性的影响作了研究，所得结论对脱硫反应的优化。

Experimental research work on the reaction between SO 2 and two dry calcium based sorbents (CaO and Ca(OH) 2) is reported in this paper.Reactivity of the two sorbents is compared and influences of some factors such as particle size,reaction temperature and four additives (Fe 2O 3,NaCl,V 2O 5 and ZnO) on reaction rate are investigated in detail.The above results is helpful to desulfurization reaction optimization,sorbent selection and the dry FGD system development.
