CaSO4-CuO-Ben载氧体煤化学链燃烧反应特性
Reactivity of CaSO4-CuO-Ben oxygen carrier in chemical-looping combustion of coal
摘要
Abstract
CaSO4-CuO-Ben oxygen earners (OC) were prepared with industrial calcium sulfate,bentonite and copper nitrate using mechanical mixing methods.The experiments were carried out in a fluidized bed,where the steam acted as the gasification medium.Effects of CuO and temperature on the reactivity of the prepared OC were investigated.In addition,the cycling stability of the OC was also detected.It shows that the reactivity of oxygen carrier is enhanced and the coal combustion efficiency is increased by adding CuO.By increasing the carbon conversion efficiency and the average CO2 concentration to 91.27％ and 89.34％,the OC CaCu 1.5(m(CaSO4)∶m(CuO)=10∶1.5) exhibits higher reactivity at 850 ℃.The ten redox tests demonstrate that the OC CaCu 1.5 is featured by the high reactivity and excellent cycling stability.关键词
