FCC脱硫助剂还原分解非等温反应动力学研究

Study on non-isothermal kinetic of sulfate reduction decomposition of de-SOx additives in fcc

以酸法制备的 1 0 %Ce MgAl2 O4·MgO和 1 0 %Ce MgAl1 .8Fe0 .2 O4·MgO为研究对象 ,利用原位热重装置 ,通过热重法 (TG -DTG)对不同脱硫添加剂形成硫酸盐的还原分解进行了非等温固相反应动力学研究 ,建立了在尖晶石上形成的硫酸盐还原分解反应机制函数模型 ,为脱硫助剂的最佳工业应用工艺条件提供重要理论依据。

Non-isothermal experiments were conducted to study the kinetics and mechanism of the decomposition reaction of the sulface-formed sulfates for two kinds of spinel solid solutions by In situ thermogravimetric unit. Reaction mechanism functional models of reduction decomposition in spinels-formed sulfates were found. Provide a valuable theory basis for industrialize appliance of DeSOx additives.
