中文摘要：
采用热重分析仪、红外频谱仪以及差热分析对PDS烟煤与溶胶凝胶燃烧合成法制备的Fe_2O3基复合氧载体的反应性能及热流变化进行了研究,发现：就Fe2O3基氧载体而言,适当增加Fe2O3基氧载体过量系数Φ有利于煤的充分反应;而铁基复合氧载体CuFe2O4与PDS煤具有更高的反应性,加入惰性载体Al2O3有利于CuFe2O4与煤一次热解产物的反应,却阻碍了其与二次热解产物的反应。CuFe2O4具有更高的晶格氧容量以及更少的吸热量,用于煤化学链燃烧中是非常合适的,具有很好的应用前景。
英文摘要：
The reaction of PDS bituminous coal with iron-based combined oxygen carrier,prepared by innovative sol-gel combustion synthesis,was systematically investigated via different experimental measures,including thermogravimetric analysis（TGA）,Fourier transform infrared spectroscopy （FTIR） and difference thermal analysis（DTA）.It was found that in terms of Fe2O3-based oxygen carrier（OC）,the increase of excess numberΦfor Fe2O3 was conducive to more sufficient reaction between PDS with Fe2O3,as OC,CuFe2O4 had better reactivity with PDS in relative to Fe2O3, furthermore,when some amount of Al2O3 was added into CuFe2O4,Al2O3 benefited to the reaction of CuFe2O4 with the products of the primary pyrolysis of PDS,but hindered the secondary pyrolysis products of PDS to react with CuFe2O4.Finally,considering the bigger lattice oxygen capacity and less heat needed to continue the reaction of CuFe2O4 with PDS,CuFe2O4 is suitable to be used as OC and demonstrated great prospect in the chemical looping combustion.
