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
