Abstract Lignite chars were produced in a fluidized bed (FB) reactor under 100%N2, 100%CO2 and 50%N2/50%H2O atmospheres, respectively. The physicochemical characteristics of the three kinds of chars were subsequently characterized, and the gasification reactivity of these chars were studied. The results indicated that the char produced under H2O and CO2 atmospheres have a rougher surface and a more developed pore structure than that produced under N2 atmosphere. The specific surface areas of different samples follow the trend: raw coal

CO2 和 H2O 对流化床反应器中褐煤焦结构和反应性的影响
摘要 褐煤焦在流化床 (FB) 反应器中分别在 100%N2、100%CO2 和 50%N2/50%H2O 气氛下生产。随后对三种炭的理化特性进行了表征，并研究了这些炭的气化反应性。结果表明，在 H2O 和 CO2 气氛下产生的炭比在 N2 气氛下产生的炭具有更粗糙的表面和更发达的孔隙结构。不同样品比表面积趋势：原煤
